Terrible mattress, never expanded to its full size so fits loosely within its cover and coils start to protrude out. Sam’s only response was to bring back to store. Terrible product and Sam’s does not stand behind it.

We got the medium for my son who's moving out. The mattress itself is super nice and comfy. The top is squishy which is great and what he wanted, but with some firmness. The only issue is that one side does not expand to the height of the other. We keep the smaller side at the foot of the bed. I measured and one part is at 13.5" while the other is at 13", so not quite the 14" advertised. This leaves the covering a little loose. I believe the unevenness is due to it being rolled and the inner part that is compressed the most has been comprimised.

I absolutely hate the cover on this mattress! It’s so slick the sheets have a hard time staying on and I feel like it moves every time I do at night. I don’t feel like the mattress ever fully expanded especially one corner so the cover is also too lose. I got the twin firm, as far as sleeping it’s satisfactory. The fact the cover zips off to wash is a great feature but please use better quality fabric!

We desperately needed a new mattress for two adults and two dogs. We are larger people and sleep with 60 lb and 12 lb dogs. This mattress is supportive for all the weight it carries from us. We got the medium so we could feel the support but also a touch of plush. Better sleep days are ahead for sure. We have been sleeping on it for about a week and my body is already feeling much better. I have arthritis and my stiffness is much improved so far. As for the unboxing, it was so simple. We opened the box and took the plastic off. The mattress looked and smelled clean. We allowed it to rise and had zero issues with it not being true to size. just buy it already!

why on Earth would you put a very silky cover on a mattress the sheets just want to slide off every time you move the sheets slide with you because the cover of the mattress is so slippery

Only had a couple of weeks now, with the price you can’t beat the value. We replaced a fairly new expensive mattress with this one and this one sleeps 10x better.

This is a pretty comfortable bed. More on the firm side, but not too firm. I don’t feel like it fully expanded as I can grab some of the fabric on the edges of the bed. It’s covered by a mattress pad and bottom sheet so it’s not a real big deal.

We bought two MM 14” medium-feel hybrid mattresses, and we could not be happier with our purchase. We sleep supported—without sinking in—and cool. And we rest for a minimum of 5-6 hours before awakening. Then it’s back to sleep. These are the best mattresses we have ever owned, and they are competing against high-end, ripoff-priced mattresses that we owned previously and that cost $6,000 and $7,500 (specialty brands from San Francisco). If you need a mattress, don’t delay. Members Mark will save the day.

I've had this mattress for about six months now, and I'm a larger heavier guy. Every night of sleep on this bed has been great, it's just the right firmness, doesn't get to hot or to cold. So far there's been no loss or difference in firmness/comfort. Completely silent, and doesn't transmit motion when getting in or out of the bed. No real complaints to it, just make sure you have help carrying and unpacking it, it is very heavy.

Worth it.
