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

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.

Great mattress

Ashley Furniture

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

Mattress

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!

PLEASANTLY SURPRISED!

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.

great matress

[This review was collected as part of a promotion.] Much more comfortable than a sleep number bed extremely satisfied with this bed and extremely dissatisfied with the sleep number

Comfortable and affordable

onmolecule.com

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

Dream Land...

I had a Sleep number bed for years and my husband gave me options to look at that with better features and a more reasonable price tag. I was impressed by the company website about how they came about ans how the bed is made. I loved the idea of it helping to relax muscles and be comfortable as a i workout 6 days a week.
Researched and went with the molecule 2 that is a bit firmer since I am a stomach sleeper.
I also like the idea of a " trial" period...it also included an amazing comforter. 
I have had the bed about 2 months now and its amazing! It is the perfect firmness and softness as well. It supports me great as a stomach sleeper. I would highly recommend. And it has been the best sleep I have had. So comfortable!
A+
Way to go

Wow...molecule 2 is the best!

[This review was collected as part of a promotion.] Really thrilled with this mattress. I feel so recharged and well rested after a nights sleep. I feel cool through the night and can't even feel when there is movement on the other side of the mattress. It's the perfect firmness and the experience and service with ordering was amazing and quick!

Really thrilled with this mattress.

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.

Good mattress

I have an injury that has made sleeping and finding the right mattress very difficult. With the number of professional athletes promoting this brand and the promise of restorative sleep, I had high hopes. Unfortunately, this is one of the the most uncomfortable mattresses I have ever slept on. It's so hard, I don't know how it could be restorative for anyone. My injury got significantly worse during the required 30 night trial, and I'm currently sleeping on an air mattress because it is the better option. Can't wait to get this thing out of here so I can get something else. FYI: While everyone in customer service is really nice, returns/refunds are not as quick/simple as they make them sound.

Definitely NOT restorative!
