Q: "Which seat cushion is the better choice for a person who must spend hours daily in a chair? Is the fleece coccyx wedge seat lumbar ortho cushion or the memory foam, etc. cushions a better choice or the Lumex skin protection positioning cushions? My mom has back problems, spends most days in a wheelchair and is in her 80's. Thanks. Steve."
Answer: The lumbar cushions have a cut-out that takes the pressure off tailbones. The memory foam are more firm than the regular foam as memory foam is more dense. These generally sell for $20 to $50, have no attachment strap (just place on the chair and sit on it). In contrast, the Lumex are retailed at over $275, have a gel center layer plus foam layers on top and bottom and have both side wedges for lateral stability and a center pommel for medial thigh support. More important they have a waterproof cover made to reduce shear/friction plus a strap for firm attachment to the chair. The purposes are to provide long-term skin protection and positioning for high-risk patients plus seating comfort.
There are also lumbar support cushions available to give her support in her lumbar region. For example, the memory foam lumbar cushion by Mabis Health Care and the Care Apparel polyurethane foam velour lumbar cushion can give her better back support in her wheelchair.
She probably would be most comfortable with the Lumex seat cushions and either of the lumbar support cushions. Do realize that the Mabis cushion does have a strap for the back of the chair if slippage is a concern.
