Thanks, everyone. I'm disappointed in myself... as a retired Army nurse, I should have thought of sheepskins... those and the early gel pads were the go-to items for patients with mobility issues. I'm glad Slowmover is happy with the Wondergel pad, but reading reviews on Amazon, many users are initially pleased but become dissatisfied and discard them after a couple of months. The tough job now is to talk my wife into springing for sheepskins (probably bottom seat pads or the panel inserts rather than $299 each for full seat covers, though).
