It's great! The set up guy said it may take a while to adjust to it...nope! First night and every night since...sleeping great! Wake up without aches and pains!
It stays cool for about 15 minutes. I love the comfort, but the mattress tends to get to warm. We bought this bed because some of the medications I'm on for my cancer cause night sweats and I thought it would stay cool most of the night. My best night of sleep so far was about 5 hours. Most nights it's 3 hours.
Our mattress was past the 10 year mark but lost comfort years prior. It's nice to sleep through the night not having to get up because my hip and shoulder ache. My husband loves having the head and feet up, i love just putting the head up a notch! I like to hit the ground running and this bed is helping me get back there.
We are loving this mattress. I used to wake up 3 and 4 times a night and never would I sleep later than 4 a.m. Now I am waking up at 7-7:30. Good thing we are retired! The only negative thing I would say is that it is hard to change positions, but being able to sleep all night and get a full night's sleep is wonderful.
The price for these mattresses and adjustable bases are outrageous! With that said, we are about 1 month into using our mattress and it is hard to get out of bed in the morning because you sleep so deeply. I swear this mattress makes you sleep longer and deeper, which is great for me. I used to take forever to fall asleep and then wake up every couple of hours between the night...not anymore. Love the firmness, yet not firm. Love the way it contours to your body but doesn't "suck" you in. One big flaw, the mattress is very hot! Supposedly it has cooling technology, but doesn't seem to work because we were both waking up in a pile of sweat. The good news is that we bought a cooling mattress pad from a local store that didn't break the bank and it solved the problem. We thought about trading it in before we bought the cooling mattress pad for the Tempur-pedic that has the most cooling technology, but that one was even more expensive. Bought the cooling pad and have no sweating issues anymore. To sum it up, price is very steep, but I have never slept better once I purchased a mattress cooling pad for it.
