[This review was collected as part of a promotion.] This mattress from Molecule is great. I'm always a little skeptical of the mattresses in boxes but once it was unwrapped and full size, it was pleasantly comfy. It's firm but still soft and forming. I love the cooling effect it provides, as I'm a hot sleeper.

This mattress is awesome! Well we haven't slept on quite yet we love laying on it. It's my daughters first big girl bad and she's not officially moved out onto it yet but it's going to definitely do the trick! I'm not sure what it'll feel like after a couple years but it was definitely worth the price for now especially for a two year-old.

Bought this for my 94 year old father he seems to be pleased with it. He sleeps well it's comfortable does have an issue with sliding off if just on the edge

My son loves his new CopperWELL Medium Gel Memory Foam 12" Twin Mattress. It's soft but supportive, and you don't sink into it. The price is great, and there was no strong smell after opening. He's been sleeping really well on it. We definitely recommend and would purchase again.

I love it cause I’ve slept on it last night and made me sleep much better than I had In years

Great mattress! We downsized from a KING mattress to a QUEEN and this one is wonderful. I love the cooling gel version and would definitely recommend!

Very comfortable, only wish they rolled opposite direction because center has a bit of a dip in the middle still waiting for it to come out. Would suggest using a solid frame or something if not using a box frame. Had to engineer a base due to bed frame I ordered with it had slats and not as many as needed.

this has to be the best mattress I have owned in a very long time. It is comfortable, I like cooling layer, I have slept so much better.

Thanks for the fast service and the Mattress is awesome, not 2 mention I sleep through the night without Waking up...

We bought the queen mattress and liked it so much we bought another one for our vacation home Unfortunately ours didn't come with the 2 free pillows advertised for either one. The more I read about this technology we do not need an additional mattress cover Love it love it our friends had recommend this and they have two as well
