This memory foam mattress supports every curve of your body for a balanced feeling that lasts the whole night regardless of whether you're a back, side or stomach sleeper.

Very good bed, definitely would recommend

I've had this Serta Blue 100 Gentle Firm for about a month. One thing I have noticed is that I definately sleep a lot better. It's quite firm, but provides enough support and cuddling for body curves, whether you sleep on your back or your side. I toss and turn a lot less, but I can't stay in one position for very long, otherwise my hips start hurting. My husband sleeps good on the matress also. He wakes less during the night and isn't tossing and turning. He prefers a softer bed just like me, but we both sleep better on the firmer bed. We don't notice the cooling effects of the bed, but that may be because we have a mattress protector on it. [This review was collected as part of a promotion.]

Do not buy

It was very comfortable at first and it does keep you cool, one side is sagging, and I've only had it for 8 months. It has a 10 year warranty but has to be a quarter inch before they will replace it. Although you can't tell until after 10 mins in bed it sags to the box spring, I will not be buying Serta again. I've spent alot of money And stuck with a bed that makes you feel terrible the next morning.

Please please don’t buy a icomfort. They brag about the warranty but don’t back anything up. We spent a lot of money on ours and started coming apart after a year and they said that none of this is cover so denied all my warranty. This is BS. And bed after a while isn’t comfortable anymore. I now have a lot of back pain but also can’t do anything about it. Just be smart and buy a different bed

I bought this mattress to see if it would help me fall asleep due to my chronic back pain. And I can happily say that the first night was the best night of sleep I have had since my back surgery 6 years ago! Thank you!

Bought 100 gentle firm to replace an online "luxury" multi coil mattress that was killing my back. Delivery and removal from a local dealer was a breeze. For 4 or 5 days there was a mild gas smell coming from the mattress when moving on it. I sleep better, sleep cool and no aches in the morning. I reserved one star because not knowing how it will stand up in the future.
