What You Should Know About Wheelchair Seat Depth
What You Should Know About Wheelchair Seat-Depth
Wheelchair seat-depth is measured from the front to the back of the seat. To determine the existing size, you need to measure the distance from the front edge of the seat to the back where the seat meets the back- upright. This will give you a depth dimension of the existing seat.
Measuring to the back-rest upholstery may result in an incorrect measurement. Most back-upholstery is stretched and "hammocked" (hung between two, free-standing, swinging supports like a hammock), so measuring from the center of the seat to the center of the back-upholstery will result in a longer and incorrect dimension, as well. Some wheelchairs have add-on backs. Many of these mount forward of the back-uprights thus making unusable any seat surface located behind the add-on back.
To determine the appropriate seat depth for a user- the user should be placed in the best possible seated position that can be obtained. A measurement is taken from the back of the pelvis (furthest part of the buttocks), forward to the back of the knee. Make sure that each leg is measured separately. There are more leg-length discrepancies (differences in leg-lengths) than you may think. Deduct 2" from the measured length for clearance.
If you have decided on an add-on back, you will need to allow for this. If the chosen back takes up seat space in front of the back uprights, you will have to add that amount back into the formula. If not, you will be scratching your head wondering why the seat appears so short on the finished product.
With no add-on back: (measured length) - (2" clearance) = depth
For chairs with an add-on back: (measured length) - (2" clearance) + (overlap-of-back on seat) = depth

If there is a leg-length discrepancy (differences in leg length), custom upholstery, seat pans, or inserts can be ordered from the wheelchair manufacturer (sometimes) or from aftermarket suppliers. Many cushion manufacturers will also custom make their products to accommodate these differences.
PROS
•A proper wheelchair seat-depth will afford the user increased pressure reduction.
•It will also enhance comfort and will promote improved sitting posture.
•With as shallow a seat as possible will assure a shorter wheelchair frame (in a manual wheelchair) which will result in a lighter chair, decreased turning radius, and easier trans-porting and storage.
•A longer depth will serve to distribute pressure over a greater area (the surface area of the seat) thus reducing pressure in any given place.
This does not hold true if the user is siting in the knees-up position with only the ischials (sitting bones} making seat contact. The pressure will still remain on the ischials no matter how deep the seat is. If the thighs do not make contact with the seat, they will not aid in pressure distribution.

Consider this- Are you determining seat-depth by measuring the user or by duplicating the dimension of a previous chair?
CONS
•An excessively long seat will push against the back of the leg or in the area of the popliteal crease (fold on the back of the knee) causing the user to be pushed forward on the seat and into a sacral (slouched) position. If left unresolved in patients with insensate (no sen- sation or feeling) lower extremities, this situation may also result in tissue trauma (sores, wounds) to the back of the leg.
•An overly-deep seat will not allow the user to sit all the way back against the wheelchair- back
•An excessively long seat will push against the back of the leg or in the area of the popliteal crease (fold on the back of the knee) causing the user to be pushed forward on the seat and into a sacral (slouched) position.
•If the user is forced forward on the seat, most of the weight will be located forward on the wheelchair making the chair harder to push
•Long seats will also add weight to the chair.
•Excessively short wheelchair seat-depths will result in increased pressure to the seating area resulting in less surface area. This may increase the risk of tissue trauma.
•The amount of support offered by the seat will also diminish possibly causing poor posture.
