It takes time to get used to using a new postural support system (PSS), or one that has been modified. We call this "building tolerance." Taking time to build sitting tolerance is important because it helps your body adjust to changes and can prevent skin sores or discomfort.

Begin using the new PSS for just 30 minutes at a time. After 30 minutes, get out of the chair and check your skin for signs of irritation. Look for areas of warmth or redness on your:

• Neck
• Back
• Shoulders
• Armpits
• Ribcage
• Elbows
• Buttocks
• Thighs
• Inside of knees
• Any other areas that come in contact with straps or supports

• If irritation is gone after 30 minutes, you can increase the amount of sitting time. Add 15 minutes, for a total of 45 minutes. Then check your skin again. Each time your skin recovers in less than 30 minutes, you can add 15 minutes to your sitting time. Do this until you are able to sit for 2 hours (120 minutes) without signs of irritation.



• Take a break. We recommend that you take a 20-30 minute break, and get out of your chair, every two hours. If you must sit for more than two hours at a time, you may be able to do wheelchair push-ups or use other pressure-relieving strategies, such as tilting or reclining the wheelchair back, or leaning forward. Ask your therapist what is best for you.

Getting into your chair
in seven easy steps:

1. Before getting into the chair, move all straps and movable supports out of the way.
2. Safely get into the chair and sit with your hips all the way back and centered on the seat. (If this is difficult, someone can tip the chair back -- make sure that the brakes are locked -- to allow your hips to slide back easier.)
3. Fasten the seatbelt or pelvic stabilizer* snugly.
4. Position leg abductor* between knees.
5. Fasten upper body straps/supports* and replace headrest.*
6. Fasten footstraps.*
7. Secure laptray* to wheelchair.
