Review on Extra Thick Kneeling Pad For Work, Gardening, Bathtub & Exercise: 18" X 11" X 1.5 by John Ford

***UPDATED REVIEW***I was very excited to get this cushion because I sometimes work kneeling and pillows under my knees were just too soft to provide safe support. This cushion is thick and firm, so it keeps your knees off the hard floor/ground. But it's too firm for use beyond a few minutes. At least for me. After about 5-minutes, my knees begin to hurt just as if I were kneeling on my marble floors with a rolled up cloth between the floor and my knees. I think the cushion would work for anyone who doesn't have any knee problems already. But if you DO have knee problems, kneeling in general may just not be practical. I even tried putting a memory foam pad over this kneeling cushion. Ultimately, I had to just stop kneeling. On the bright side, this cushion is firm enough to support a heavy load if you need an anti-vibration mat (for a small stereo.).***ORIGINAL REVIEW***I just got this today. I sometimes like kneeling while I work at my computer. This hurt my knees. I tried many other solutions--rolled towels, yoga mats, knee braces (workperson's knee-guards). Everything else was uncomfortable. But this pad is hard enough not to flatten to the painful floor, yet spongy enough to keep my knees happy. I bought this on a whim and am glad I did. I'll update my review if the product deforms permanently (flattens too much).
