My husband is wheelchair bound. He always had butt and knee pain because the knees would come together in the middle. I researched to see what could help and found this. Ever since we placed it on the wheelchair and put the cushion on top, his pains went away. I highly recommend this.

Great wheelchair seat insert and great price.

I really love this wheelchair insert! I'm in a wheelchair for long periods daily. I love that it is water resistant. I've tried many more expensive wheelchair pads and this one works great for me as it also helps relieve some of my back pain.
