Quality made, gel in 4 compartments keeps gel in place, foam base provides support, water proof cover ordered extra protects the cushion, fits my extra large wheelchair, comes in multiple sizes, strong velcro keeps cushion in place, no slipping at all.
I don't know of any weaknesses so far. I haven't tried to clean the cushion covers yet but I expect that to go well.

I use the cushion myself. I am a 70 year old female who uses an electric wheelchair full time for advanced degenerative spine disease and RA.
