SITTS Posture Cushions Integral Skin 4 in Memory-like 1 inch Serene Pad-Soft Wedge Cushion helps Reduc Sciatic Pain with Ergonomic Correction at Computers/Office Chair Seats & Cars Seat. Endless Uses,

Cushion is one of the more well-designed ones on the market. It definitely helps with alignment during sitting. That said, I do find the sitting area to be too small for wide hips. It is made of a unique material that is easily cleaned and does not degrade as quickly as other cushions. It also is less likely to absorb body odors. The major problem I have with it is the smell of the cushion itself. It gives off a strong chemical odor that has not dissipated with five days of airing. I am very sensitive to chemical odors and cannot tolerate sitting on it for that reason.

If I could give this 3.5 stars I would. I had bought this for my car seat but it's too wide and won't fit. Also, the cushion/cover is too small for the pad. I have been using it when I sit on the sofa for any prolonged period of time. Not sure if it's helping. I still have significant sciatic nerve pain when try to watch a tv show or a movie.

I like the cushion, but it slides around in in my chair.

I purchased the 2.5 integral skin with 1" memory -pad. I am pleased to report increased sitting tolerance and decreased back and radiating pain from using the cushion at the dining room table chair and my desk chair. Purchased an additional cushion so I do not have to move it from chair to chair. SITTS perfect company provided excellent customer service and assisted me in getting the right height to fit my needs.
