The mattress protector appears to be too big and does not fit snugly on the Pro-Adapt Hybrid mattress. It easily slides off easily, which is frustrating, so we contacted Tempurpedic to return the non-functional product, but they refused, citing a non-returnable policy, which is absurd for something that doesn't fit properly. Perhaps it may fit more thicker mattress but it clearly doesn't fit mine.

Tried on different both ways and can not get it to fit snug. It moves around when sleeping and is loud and uncomfortable. Very disappointing for the price.

Received the Mattress Protector and immediately put it on the mattress without a problem. I felt my mattress was well protected which is what I wanted.

Nice pads when it stays on the bed which is hardly ever disappointing not the same quality when we bought it years ago!

The king size protector is too large for our King size Tempurpedic mattress. It does not stay on & often bunches up & moves around under the sheets. I would not recommend it if you have an 11 inch tempurpedic mattress.

It is great material but it does not seem to stay on the mattress. Every time I set the bed up it slides off no matter what I do. In turn it makes my sheets slide off. Not too happy with that at all sad to say

[This review was collected as part of a promotion.] The mattress we got was cooling. It cools without making you feel cold. I'm usually a hotter sleeper but in general I'm always cold. Haven't woken up hot once since buying the bed (have had it for about 5 months now). It's firm at first, but you settle in where it still supports but you feel like your in a pillow at the same time. I was worried that when I rolled over it would take to long to regain its shape and I would roll back into it, but that hasn't happened once. The elasticity is far beyond what I thought a bed could have. We also bought a mattress pad to protect the mattress and it doesn't prevent the above from changing. I don't know if this was intended but the mattress pad doesn't seem to be the right size for the mattress. I checked multiple times that it matched the size of the mattress, but it's not a snug fit so sometimes I feel the creases of the extra fabric in the mattress pad under the sheets. Not a deal breaker but for the price I feel it should be a bit better constructed to fit a product it was made for. Overall I highly recommend for anyone who fits the same criteria I do.

after I changed the flannel sheets for the summer to the light ones, the mattress cover doesn't. stay on the bed.
