WORTH THE MONEY
If you're like me you may have found this item on AMZ and been like "150 bucks ?!?" And I was. Then I burned through three competitors that were admittedly much cheaper, and also are all three now at the Goodwill. The bottom line is this cushion is FOR REAL 2.5 inches thick - and unlike other cushions, that 2.5 does not become .5 when you actually sit down. I have not done the "egg test" but I have no reason to believe it won't work - this is real technology, not just some foam from China. However, as you can see in the photo, this cushion is LARGE, though waterfalled to help circulation. 5 stars. No regrets.
Rating: 5 stars
