Rated 5 out of 5 by from Definitely Recommend Very comfortable bed! Best bed I’ve ever slept in. Would definitely recommend

Rated 5 out of 5 by from Best Nights Sleep I am in love with my new mattress from Serta. I have always known that Serta has a good reputation, why I waited so long to purchase a new iComfort mattress I do not know. My mattress & adjustable base was delivered and assembled by 2 professional men. I have had 2 glorious nights of the best sleep I can remember. I’m a side sleeper & sleep hot. This mattress is like sleeping on air. On my old mattress my hips would ache after a nights sleep. After the past 2 nights of sleep I haven’t had any pain in my hips or back. If your old mattress is keeping you up at night do yourself a favor and try the Serta iComfort 4300 mattress. I chose the plush mattress for my sleeping habits.

Rated 5 out of 5 by from The most comfortable bed I've ever slept in wandered into Living spaces knowing that I wanted to purchase a king sized mattress, and that was all. A kind sales person gave us the scoop on the mattresses and had us lay down on them. We opted for this one because of the brand names reputation and the comfort. This type of mattress was completely new to me. It's been the best purchase I've made with no regrets. When you lay down, the mattress conforms to your body with any twist or turn you make. Speaking of twists and turns, if you or your partner are one to move around a lot in your sleep, don't fret; you'll save time by not having arguments because you'll never notice or be awakened by your partner moving around. However, if you have someone who steals the blankets, you'll run into problems. I have to say that I am not able to notice the cooling top only because I've got a mattress protector, sheets and blanket on top of that, but if you sleep with a regular sheet, in sure you'll experience the cool effect. It's been nice to get a great nights sleep and wake up without aches and pains.

Rated 5 out of 5 by from Dangerous It doesn’t let me get out of bed. You can’t even feel someone is in the bed with you...or when they leave...I’d sleep till I pee my pants if I don’t have my alarm on... this bed is a trap...once you get in, you will never want to get out. Buy at your own risk.

Rated 5 out of 5 by from iCOMFORT CF4000 PLUSH QUEEN MATTRESS I love this mattress. Just the right balance of firmness and plush. It also retains its coolness. Feels just right.
