I waited a week to write my review so I could evaluate the features and comfort of the mattress. Before you buy, consider the height of the mattress. Options are 9” or 14”. I opted for the 14”, not realizing it is too tall for me to sit on the edge and put my shoes on. There were no unpacking instructions. The box was heavy and bulky-definitely needed two people to maneuver it in to place. The mattress info in minutes and we were able to sleep on it the first night. I find the mattress very comfortable. I am sleeping through the night, unlike my old mattress when I would toss and turn. I don’t notice the “cooling” feature - temperature feels the same as my 8 year old mattress. Overall, I am happy with it.

You guys this mattress is like sleeping on a cloud. It keeps me cool it’s soft yet firm in someplace. It’s just like what my back needs very easy to get out of the box. The box was a little crushed when it came to my house, but other than that, everything was in tapped very easy set up and so very comfortable!!! I’ll probably end up having to upgrade my children children’s beds to this brand

We bought two of the XL Twin size to replace our King size mattress, and use them on a pair of matching adjustable bases. We’ve only had them a couple of weeks, but so far we're both happy with them! This 14" thich mattress works well with the adjustable base, though a thinner mattress might work better.

I first slept on this mattress at my friend's house in her guest room. I had a wonderful ngihts rest. I had recently purchased a mattress of my own. But after trying sleeping on this mattress, I had to return my previous purchase. This mattress is a 10 out of 10.

We ordered 2 Twin XL mattresses. Boxes claim to be Twin XLs but when we opened the boxes and allowed the mattresses to expand they measure as a regular Twin size mattress, 5 inches shorter than a Twin XL. All tags on the mattresses claim to be Twin XL.

Ordered this mattress for my sister in San Antonio. FedEx showed it to be out for delivery for 4 days. Had to cancel the order and re-order for pick up because FedEx could never tell us where the mattress was. Sam’s really needs to rethink their delivery carriers.

1 year review of the medium mattress by a 230lb side sleeper: Month 1: Foam was is so thick, its cloud like. Felt more like a plush than a medium. Months 2-3: Perfect. Slept great. Months 4-5: Noticing the foam layers are beginning to lose their loft. Month 6: Foam is starting to bottom out, I began to feel the coil spring layer on my side. Months 8-9: Mattress foam was no longer providing any support. I felt as if i was sleeping on a firm coil spring bed. I began thinking I'm going to need a new mattress soon.. 12 months: Mattress has been replaced and now in the towns dump where it belongs. I had high hopes for this mattress but the long term just isn't there.

We absolutely love this mattress! The mattress is so incredibly comfortable. We love that it is Cooling so it helps us not sleep so hot and helps ensure that we get a full nights rest. Our kids always ask to sleep in our bed because it’s so comfortable

Overall the mattress is nice and comfortable, however it is not a true king size mattress. The specs on the website list it as being 76x80, but it is only 77" long. When I put it in the bed frame I noticed a large gap at each end compared to our old mattress. My feet hang off the end. I guess that's how they offer the Sam's discount by removing 3 inches from every mattress.

My wife wanted to replace our $2,500 Stearns & Foster mattress because she sunk into her sleeping position after a few years (the mattress basically had divots in it where we slept). I didn't want to spend another $2,500 on a mattress so we compromised on our first ever mattress in a box. So far, it's been great. The only advice I'd add is medium is firmer than we expected. We're not disappointed - and we haven't tried the plush or firm - just saying our experience with the medium is that it's more like "medium-firm."
