We bought these sheets for our adjustable bed. We already had the Bedgear mattress protector and were hoping these sheets would help the cooling technology actually work. I love how the sheets fit the bed and stay put. Unfortunately, the pillow, while in the pillowcase, slides all over the bed. Additionally, as others pointed out, the blankets have a hard time staying on the bed. I can deal with these two things for the most part. The most disappointing thing is they are HOT! These sheets do not keep you cooler, they actually make you hotter. I'm so bummed about that because they really are comfortable to the touch and I don't slip around on the bed (other than the pillow) like with the cotton sheets we had did. So far we've purchased two Bedgear items, both with supposed cooling technology, and both are disappointments on that part. I'm sad I spent so much money for these products only to be disappointed because they don't do what the description says they do - it does the opposite.
