Carpet [4.5.3]

Carpeting can significantly increase the amount of force needed to propel a wheelchair over a surface. Studies show that the level of roll resistance of carpet, even low-pile carpet that is properly secured, is considerably higher than the roll resistance of firmer surfaces such as concrete and linoleum. The firmer the carpeting (and backing), the lower the roll resistance. A pile thickness up to ½ inch (measured to the backing, cushion, or pad) is allowed, although a lower pile provides easier wheelchair maneuvering. If a backing, cushion or pad is used, it must be firm. Recommendation: Preferably, carpet pad should not be used because the soft padding increases roll resistance.

There should be minimum movement, none if possible, between the cushion or pad and the carpet. In high traffic areas, where this attachment may loosen or where a thick soft (plush) cushion or pad is used, wheelchair travel can become very difficult. Secure attachment to the floor is important to prevent buckling or warping. Trim is required along the full length of any exposed edges. This helps keep carpet from curling which can pose a tripping hazard and make wheelchair traffic difficult. The trim must meet requirements for changes in level.
