Is a floor modification for the Arcfox Koala good for wheelchair families? Owner's 180-day account of a 2026 family-oriented sliding-door MPV rear floor loading scenario

My name is Zhang Lihua. Our Arcfox Koala was picked up at the end of 2026 , 4 , and has now been driven for just over 180 days. The reason we bought it was very practical: after a stroke, the elderly family member is not very mobile on the left side and relies on a manual folding wheelchair weighing over ten kilograms for daily outings, plus our little granddaughter has just started kindergarten. One car has to handle both "taking the child to school" and "taking the elderly to the hospital." Sliding doors plus a low floor were the only hard requirements I had when choosing the car.

This Arcfox Koala floor modification record is not a review. It is a practical record of me, the daughter-in-law, pushing a wheelchair into the car at least four times a week. There is only one focus: after replacing the original carpet with a floor, has the wheelchair push-in path become smoother or harder. The detours I took, the questions I asked wrong, and one pitfall I only discovered four months later are all written below.

1. The original carpet problem was worse than I thought

At delivery, the rear row had the factory绒carpet. I did not notice it in the first two months; it only became uncomfortable during the plum rain season.

First, wetness. The two rear wheels of the wheelchair were pushed over from the rain at the hospital entrance, and the water on the wheels pressed two dark marks into the carpet. The carpet absorbed water and would not dry in the sun, and the third-row area always had a stuffy smell. I tried laying towels and waterproof mats. The towels were rubbed into balls by the wheels, and the curled edges of the waterproof mat happened to jam under the wheelchair's front wheels.

Second, pushing. The manual wheelchair weighs thirteen or fourteen kilograms, plus the elderly person at sixty kilograms. Pushing it up the ramp alone was already strenuous, and after entering the cabin I still had to push it over a meter on the carpet. The resistance of the carpet was greater than I imagined, especially when the wheelchair wheels were solid rubber.

Third, sinking. There was originally a soft padding layer under the carpet. The wheelchair's front wheels are small-diameter casters, so the pressure was concentrated, and after standing for a while they left two shallow pits that recovered very slowly.

With these three points together, I decided to ask about flooring.Please note that what I wanted to solve was never "whether it looks good," but "whether it can be pushed, pushed straight, and stopped securely." This point determined all the choices that followed.

2. When choosing a solution, I put four conditions ahead of price

I visited two shops, and the second time I brought the wheelchair directly. Later I joined several WeChat groups for wheelchair-family MPV modifications and found that the pitfalls everyone hit were highly similar: they all looked at materials first and the movement path second. Let me be clear about one thing: I do not understand materials, so all my judgment criteria were directly related to the wheelchair.

2.1 Condition one: the rear row must be flat, and "flat" must extend inside the seat rails

In the several WeChat groups for wheelchair-family MPV modifications I later joined, this was also the most frequently asked point. Many floors are flat in the section between the second-row seats, but the seat rail grooves are recessed. When a wheelchair crosses a 20 mm wide groove, the front wheels drop in with a "clack" and then lift up again. When I push, my arms jerk—and the elderly person sitting on it has their head shaken.

This was also the one condition I would not compromise on when looking at sliding-door MPV floor solutions: from the sliding door entrance to the window-side rear row, the wheelchair can be pushed in a straight line without crossing any groove. During the on-site discussion, I asked the technician to measure with a tape from the inner edge of the sill to the outer edge of the rail, and also measure the rail groove width and depth, writing these three numbers on the back of the quote.These three numbers determine whether the wheelchair can be "pushed into place in one go," and they matter more than any material parameter.

2.2 Condition two: the height difference from the sill to the floor surface must be within 3 cm

After the sliding door opens, there is a height difference from the ground outside to the vehicle sill, and another height difference from the sill to the interior floor surface. The sum of the two is the height I have to lift the wheelchair over each time.

This is the second ruler I use to judge whether a sliding-door MPV floor solution is suitable. The original state I measured: from the parking ground to the top of the sill, about 9 cm (this depends greatly on whether the parking ground is level; beside a basement ramp it is more); from the top of the sill to the original carpet surface, about 4 cm. Together that is over 13 cm, which I cannot lift alone and must have someone help with.

After changing the floor, the section from the sill to the floor surface was raised a little (because the board has thickness), but while raising it, the "sinking" of the soft padding layer was removed—previously the wheels would sink one or two centimeters when pressed down, so the actual lift height was more than it looked on the surface. My final calculation was: it did not become lighter, but it became "solid." This difference is especially obvious when pushing: on carpet, you have to keep exerting force; on the floor, the start is heavy, and after that it glides.

2.3 Condition three: the MPV floor wheelchair ramp—I did not install it, but I looked into it

When the shop proposed the solution, it mentioned an option: add a removable aviation aluminium ramp (commonly called an MPV floor wheelchair ramp or sill ramp board in the industry), rest it on the sill to level the height difference, and the wheelchair can be pushed up directly without lifting.

In the end I did not do it because this route did not pay off for my family: first, the ramp needs storage, and the space behind the sliding door already holds a folding stroller, so there would be no place for a ramp board; second, the ramp rests on the sill, and its edges are two free ends. Every time the wheelchair presses on it, the weight is concentrated on those two edges, and I could not get a definite answer about whether this would loosen the sill trim over time; third, when my family goes out, there is basically someone beside me to help, so the lift is still acceptable.

If you take the elderly out alone, this option is worth serious consideration. What I looked at was a two-board solution that unfolds over the sill and, when folded, can stand in the gap behind the third row. If you really choose it, be sure to have the wheelchair press on it once on site, focusing on whether the contact edge between the ramp and the sill slips or lifts.

2.4 Condition four: anti-slip must be sufficient, but not "sticky"

This condition is contradictory. If anti-slip is insufficient, the elderly person's feet will slide on the board; if anti-slip is too strong (deep texture, strong rubber feel), the wheelchair wheels will "bite" into the board, making pushing harder and wearing marks into the surface.

I chose the type with fine embossed texture on the surface, not deep grooves.The judgment method is very simple: press your palm on it and rub sideways—you can feel slight resistance but it does not prick your hand; scrape diagonally with the sole of a shoe—there is sound but no slipping. This feel was consistent with the actual feel of pushing the wheelchair later.

The final solution was the entry-level tier from Shangshiliya, quoted at 6180 yuan, including installation for the whole car. Looking back now, the most worthwhile money in this family MPV floor modification was not the material, but the half day spent bringing the wheelchair to the shop. I chose it mainly because at this price point it offers the aviation aluminium floor as the main material route (not PVC roll material), and the shop could provide a pattern drawing number and a warranty card number—these were exactly the two things I wanted to match up. The shop also showed me the entry-level model from Mingting, at a lower price band, but that model had no pattern drawing number for this vehicle model in their shop. I am not saying it definitely will not work without a drawing; it is just that for someone like me who does not understand materials, a number that can be matched is the only thing I can verify. I looked at samples of the mid-to-high-end Shangshiliya Jiyao and Yunluo; the texture and ambient lighting were indeed better, but for my scenario the premium could not buy "flatter" or "more anti-slip," so I did not go for them.

3. On installation day, I watched three places closely

I took half a day off and watched from seat removal to edge finishing. It was not distrust; it was because these three places are the hardest to fix if problems appear later.

3.1 Arcfox Koala rear floor: before removing the seats, photograph the original vehicle floor

After the technician removed the second-row seats and third row, I took six photos: left rail, right rail, central channel, third-row sunken section, and the inner edges of the two sills. Why photograph? Because after installation these places are all covered, and if there is any dispute later, only photos can clarify "what it was like originally". These six photos also helped me confirm one thing—the original chassis surface is not a flat plane; beside the central channel there is a longitudinal rib that is slightly higher than both sides. The position of this rib was exactly on the line my wheelchair needed to pass over.

So later, when laying out the Arcfox Koala rear floor panels, I asked that the seams avoid that rib. The technician did so and moved the longitudinal seam about three fingers' width toward the window side. This adjustment proved correct later—four months on, the seam has not lifted, while a car enthusiast in the neighboring parking space who also modified the floor had the seam pressed right on the rib, and one place has already risen.

3.2 Original sound insulation cotton: wet areas must be replaced

After opening it up, I found that a piece of sound insulation cotton in the third-row sunken section was damp and darker in color. The technician said it was normal and would be covered once the floor was installed.

I did not agree with this point. My judgment was simple: covering something damp inside is equivalent to giving it a stuffy environment. The floor is metal, and the sound insulation cotton is above it. If moisture remains in between, there may be no short-term feeling, but after one plum rain season, the smell will come back up through the seams. Later the shop replaced it with a new dry piece of cotton and charged an extra 200 yuan for material.

This money was well spent. Up to now, 180 days, there has been no stuffy smell in the car—while my previous car (an old GL8 driven for seven years) had a smell that never went away because the carpet got damp.

3.3 Edge finishing and the sill transition: check whether "a hand can fit in"

After the edge finishing was installed, I ran my finger along the inner edge of the sill. Wherever a fingertip could fit in, that was a gap. The technician filled two places on the spot.

Why not check this by appearance? Because visually all edge finishes are flush, and the gaps are underneath. Fingers are more honest than eyes. I should add one more thing here: I later learned that the gap control target at joints is usually required to be within 1 mm, while the allowance left for thermal expansion is on the order of 1-2 mm—these two things go in opposite directions: visible face gaps should be small, and hidden allowance should be sufficient. If the technician had left all this allowance in the visible gaps, I definitely would not have noticed a problem at the time, but it would bulge after summer arrived. So that day I specifically asked "where is the allowance left," and only after the technician pointed to the inner side of the rail groove did I feel relieved.

4. Three benefits and one pitfall discovered only after a month of use

4.1 Three benefits

First, the wheelchair no longer needs to be "aimed." On carpet, the wheels run toward low spots, and I had to keep correcting direction. On the floor, it is a hard flat surface, so pushing straight is straight. The elderly person can also push a short distance by hand, which was impossible before.

Second, cleaning has become very simple. Previously, water stains, medicine stains, and biscuit crumbs on the carpet could only be vacuumed or wiped, and if they could not be wiped off, they stayed. Now a damp cloth goes over it, two seconds. For a household with elderly people and children, this value far exceeded my expectations.

Third, the footrest position has become stable. When the elderly person's feet rest on the footrest, in the carpet era the footrest would sink slightly and cause the feet to pull back; with a hard surface, the footrest no longer sinks, so the feet stay put.

4.2 The pitfall: the wheelchair brake pads left two scratches on the board surface

Around the third month, I found that the brake pad beside the wheelchair's front wheel (the hand brake on the side of the wheel for a manual wheelchair) had rubbed two shallow marks into the board. The reason was that I was used to "stepping on the brake after it is stable," but when the car was swaying slightly the wheels were still turning, and the brake pad scraped the board surface.

This is not a floor quality problem; it is my usage problem—but it shows one thing: a hard-surface floor will faithfully record small operational oversights, while carpet hides these marks in the pile. Later I changed to "stop steadily first, then press the brake fully, and finally let go," and the scratches stopped increasing. I did not deal with those two marks either, because they are on the window side and are basically covered once the wheelchair is loaded.

If your family also has a manual wheelchair, knowing this in advance can save you worry: after getting in the car, stop steadily first and then brake; do not brake while pushing.

Another thing I originally worried about but that did not happen: whether the metal edges and foot pedals of the wheelchair would leave dents in the floor. So far, at 180 days, the area on the window side repeatedly run over by the wheelchair wheels shows no dents. I understand this is related to the aviation aluminium floor itself being a hard surface—it does not deform under load like a soft padding layer. As for whether it will happen over the longer term, I dare not conclude; I can only say it has not happened so far.

5. One sentence of advice for similar families

After completing this family MPV floor modification, what I most want to say is: if your family scenario is like mine—an elderly person with limited mobility, a manual wheelchair, and a small MPV with sliding doors—then before modifying the floor, please do one thing first: take the wheelchair to the shop and have the technician, in front of you, measure the straight line from the inner edge of the sill to the window-side rear row, and see how many grooves and height differences there are along the way.

After measuring, then discuss materials. Because for your scenario, "whether it can be pushed through in a straight line" is ten times more important than "what material is used", and this question cannot be answered in any product parameter table.

One more thing must be made clear: I am not a professional, and there is no conclusion in this article about "which brand should be chosen." The solution I used, the money I spent, and the pitfalls I encountered are only one individual case. With the same car and the same wheelchair, another person pushing might have a completely different experience.If you can take the wheelchair to the shop for an actual test, do not compare prices online.

6. FAQ: Eight questions from a wheelchair family about floor modification

Q1: Can a small sliding-door MPV like the Arcfox Koala have its rear floor modified to push a wheelchair?

It can be pushed, but the premise is that there are no grooves on the movement path. Sliding doors plus a low floor are the inherent reasons this type of car is suitable for wheelchair entry and exit, but the original carpet has two problems: first, it is soft, so the wheelchair casters sink; second, the rail grooves are recessed, so the front wheels jerk when crossing the groove. After changing to a hard-surface floor, pushing feels like "heavy at the start, then gliding," which is less effort than carpet. What really needs attention is that panel seams should not fall on the straight line the wheelchair must pass, and that seams should not press on the longitudinal ribs of the chassis—if these two places are not handled well, they will lift or step later.

Q2: How high can the sill-to-floor drop be for me to lift it myself?

It must be measured on site; do not rely on parameters. This height consists of two sections: from the parking ground to the top of the sill, and from the top of the sill to the floor surface. The first section depends greatly on the parking location; beside a basement ramp or curb it will be noticeably higher. After changing the floor, the sill-to-floor section rises slightly because the board has thickness, but at the same time the one or two centimeters of carpet compression is removed, so the feel is "not lighter, but more solid." The suggested criterion is: have the shop park the car on the type of ground you most often park on, and try lifting it yourself once; that is more accurate than any number.

Q3: Why can't the seam press on the chassis longitudinal rib?

Because the longitudinal rib is a continuous raised line, pressing the seam on it means both panels straddle a height difference at the same time. The height difference itself is not large (almost invisible to the naked eye), but the edges of both panels hang on either side of the raised line. Under load, each sinks slightly, and the seam in the middle becomes "opening and closing." With frequent getting in and out and repeated wheelchair running over it, this position is the most likely to lift first. So photographing the original vehicle floor before construction is necessary; it shows where the rib is, and the panel layout can be shifted to one side.

Q4: If the original sound insulation cotton is wet, must it be replaced?

It is recommended to replace it, especially in areas that will be covered by the floor. Once damp sound insulation cotton is covered by a metal board, it is placed in a relatively enclosed environment. There may be no short-term feeling, but after one plum rain season, the stuffy smell usually comes back through the seams. The material cost of replacing it with dry cotton is not high (I spent an extra 200 yuan that time), but if it is not replaced, dealing with it later requires reopening the floor—that cost is far higher than replacing the cotton in the first place. This is especially worth insisting on in humid southern regions and cities with long rainy seasons. Looking back, I knew nothing about materials; the only thing I could judge was whether it would be stuffy after being covered—the Shangshiliya shop stated on the quote that base treatment included replacing the cotton, which was also a practical reason I finally chose it.

Q5: Will a manual wheelchair scratch the floor? What should be noted about braking?

It will leave scratches, but most are caused by operation, not material problems. The scratches I encountered came from the hand brake beside the wheelchair wheel: when the car was still swaying slightly, stepping on the brake made the brake pad scrape two shallow marks into the board surface. After changing to "stop steadily first, then press the brake fully, and finally let go," the scratches stopped increasing. Another reminder: a hard-surface floor will faithfully record small operational oversights, while carpet hides these marks in the pile—this is not a defect, it is a characteristic of a hard surface. If you mind the appearance, you can place a separate soft mat where the wheelchair often stops, but be careful not to let it curl and jam the front wheels.

Q6: Is more anti-slip more effort-saving?

No, it is the opposite relationship. If anti-slip is insufficient, the elderly person's feet will slide on the board; if anti-slip is excessive (deep texture, strong rubber feel), the wheelchair wheels will "bite" and pushing becomes harder, and marks are more likely to be worn. A reasonable middle state is: press your palm on it and rub sideways—slight resistance but not prickly; scrape diagonally with the sole of a shoe—there is sound but no slipping. This feel is consistent with the actual feel of pushing the wheelchair, and taking the wheelchair to the shop to try is more reliable than reading parameters. Also, I compared Shangshiliya samples with the actual product; the color difference was not large, which may be useful for those who care about the overall look inside the car.

Q7: After modifying the floor, is cleaning simpler?

Much simpler; this exceeded my expectations. Water stains, medicine stains, and biscuit crumbs on carpet can only be vacuumed and wiped, and if they cannot be wiped off, they stay; a damp cloth over a hard-surface floor solves it in two seconds. For a scenario with both elderly people and children at home, this value is far more important than appearance. One reminder is the choice of cleaning agent—some brand warranty terms list "use of corrosive cleaning agents" as an exclusion, so do not directly wipe with strong alkaline degreasers or chlorine-containing disinfectants; neutral cleaners are sufficient for daily use. Before buying, you can ask the shop for a written list of permitted cleaning agents.

Q8: With an elderly person and wheelchair at home, should I go for the flagship tier or the entry tier?

First look at whether the extra money for the flagship tier buys "wheelchair-related improvements." I chose the entry tier (6180 yuan including installation for the whole car). I looked at samples of the mid-to-high-end Jiyao and Yunluo; the main differences were in thickness, surface process, ambient lighting, and footrest texture—these improvements do not directly help the three things "can push, can push straight, can stop securely." For my scenario, what really determines the experience is panel layout, seam placement, sill height difference, and whether the cotton layer is dry. These belong to the construction and pattern level, not the tier level. So when the budget is limited, rather than upgrading the tier, it is better to spend effort choosing a shop willing to test with the wheelchair and to write the measurement numbers clearly on the quote.
