Be carful sitting on the side of the bed. The topper is so soft you tend to slide off of the bed. We purchased the topper because our tempur- pedic mattress was out of warranty and had developed a sagging pattern in the area where I slept each night. We thought the topper would be cheaper than buying a new mattress. It was cheaper but it did not solve the sagging problem. My wife is not dissatisfied with the topper, but I sure am.
Purchased the adapt topper for coolness. It makes it so slippery, the mattress slips off the bed and the sheets pop off. I purchased jersey knit sheets which are better but still pop off. Although a return has been offered, I would prefer you fix the problem. I bought this product specifically because of the cool cover.
This mattress topper has the classic tempur feeling, which is a slow sinking type of memory foam (if you ever felt their pillows or beds, you know what I mean). I love this compared to other memory foams. It is not too soft either, which I really like. I wouldn't want this any softer than it already is, or it won't feel supportive enough. My girlfriend is around 120 pounds and I am around 175 pounds -- we both found it incredibly comfortable. The cover is also a very high quality knit and is removable/washable. The initial smell lingers for about a week, but it didn't bother me too much. I didn't find it too hot either, but definitely warmer than my plain old spring mattress. For the price I bought it for (discounted to $240), it was well worth it. It also 3 inches, which is thicker than competing brands for the same price (usually only 2 inches). If your mattress is too hard, I completely recommend this topper to completely transform your mattress. (I can't comment on longevity, as I've only had it for a couple of months, but I believe they have a good warranty...)
It took a little getting use to, but very comfortable, able to sleep longer, and my husband now doubled his sleep time....he had 5 bulging discs in his back. Thank You!
We have an adjustable air bed whose pillow top was not soft enough. Problem solved, we have been sleeping very well for the 6 weeks that we have owned this with longer & more restful sleep. Soft but very supportive, does not sleep hot, and has a very good warranty! Love it so far!
