Ordered the "medium" version first. We are going to return it and exchange for the plush. My wife is a side sleeper, and I am a back sleeper. So, we're trying to find the "middle ground" where we're both comfortable. I will update this review (or post a second review) once we get the Plush version in. That said, the bed is comfortable and seems to be well made. We've been on it about a month now, and while we do like it, the medium is just too firm. We're 5'7"/5'10", and ~130-170 lbs. Hoping the Plush version is softer. That said, I called Sam's club service number. They are having someone come pick up the mattress. This is great customer service. In the meantime, I have ordered the plush. I'm hoping for the best, but also I am purchasing confidently because of the great customer service I just received.

So comfortable! And great price! I was in a bit of a rush to buy a mattress for some guests coming over. So, I didn’t fully read the full description on the box before buying. I didn’t realize this is actually a spring mattress with a memory foam top. The relatively small packaging tricked me. But, I was definitely not disappointed! The spring/foam combo is so comfortable!

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 were sceptical about a bed in a box but our sleep number got damaged so we found ourselves needing a mattress in a hurry in a Sunday so we ran to Sam’s and got this one to try until we could get a “good” one later. To our surprise, the mattress is super comfortable. We’ve had it two weeks now and we both love it. No tegrets.

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 work at a mattress store... all we sell are mattresses. That being said, my expectations are always high, and my standards are as well. This mattress feels EXACTLY the same as our previous queen size that was more than double the price. It is so unbelievably comfortable and supportive. Its worth the price for sure and i would buy it again tenfold if we need more mattresses in the future for other rooms

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.

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."

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.
