## Description

UPGRADED JUMBO SIZE - Different from the small size on the market, the size of our gel seat cushion has been increased to 20＂x19.7＂x1.9＂, which is larger and thicker than other gel cushions can better match with your chair, to ensure that it can be used comfortably on any type of chair and any body shape.

Review: It’s Working! - The 20 inch. gell cushion is worth every penny to me! Only one problem, I WISHED I would have thought/seen something like this couple years back. This cushion is relieving most (way better) of my pain on both sides of my rear. Hopefully, it helps on somewhat the healing process. “Bed sores that haven’t opened.” I am 6ft 1inch tall and weight 240 lb’s and it’s holding me up and comfortable. I would like to try one out about a inch thicker and in around the 26”x26” in diameter, but not having any luck so far on finding one. Most products like this are sized for wheelchairs, and I’m not in one. I believe would give a little more room for my size, couch, bench etc. As for bed use, it’s uncomfortable too much pressure on lower back. Now!, one size (full body) like this gell cushion that you can lay on, could be even better! Because I’m at the point where lying down is bothering me down there too. I’m gonna be looking into that too one day. Again, five stars, because I’m getting relief. Thank you.
Review: Think twice before purchasing this item - Product didn’t work out. The comfort level was poor and it was too small overall.
