I've had the Nexgel Latexgel mattress for only a few days and am pleased with its comfort and support. My main concern is whether it will develop indentations with use -- only time will tell. One thing to watch out for: the mattress was shipped to the store tightly compressed and rolled up to fit in a relatively small box. It had been in stock at the store for about 3 weeks when I bought it, and when I got it out of the box it didn't expand to its proper size and shape. After 24 hours out of the box, about a foot at each end of the mattress remained compressed by a couple of inches and the matttress was 2 to 3 inches shorter than the foundation. A prominent sticker on the box read "Open Immediately", which apparently was directed at whomever received it from the factory, in this case the store, which must have assumed that the directive was meant for the final buyer. Anyway, it appears these mattresses can be permanently damaged by such prolonged severe compression, and it's somewhat surprising to me that the factory would risk shipping them that way to save a few dollars on transportation. The store readily exchanged the mattress for the only other one they had in stock, which happened to be the one they had on display. I would suggest that if you buy one of these, don't accept delivery until it's out of the box and you can be sure it's okay.
