DREAMY! We purchased two more expensive mattress only to return for these. We are not fans of memory foam and this is a true hybrid. We choose a king split - (2) twin XL, one plush and one medium. Heavenly! The plush is very soft and the medium is on the softer side as well. Personally, I do not feel the “cooling” aspect, but they are not hot like most memory foam. Fluffed up in a couple hours and slept on them same day. Hopefully they will hold up overtime, but you cant beat the price! Highly recommend!

This bed is not a King size mattress- it is too short in length and too short in width, now I have gaps all throughout my bed frame. I wish I would have looked at the bad reviews first. It took forever to arrive as well - there were so many bad instances when ordering and receiving this bed. DO NOT BUY

Ordered the medium Cal King mattress. Seemed like a very comfortable and solid mattress. Inflated very quickly. I like a firmer mattress and this one was just a little soft for me but a good compromise with my wife who likes a softer mattress. However, noticed almost immediately though that the bed was short. A Cal King is supposed to be 84 inches long. This one was about 80 1/2 inches long. Literally the size of a regular king and was way short for the bed frame. I let it sit for almost a week, never got longer. Not sure if it was a defect or that's just the size they made it. Returned.

Ordered King Medium. This was my first hybrid bed in a box. I have had the mattress for 6ish months... i am a side sleeper. Female, 53, 165 pounds and 5'4. At first it was good...but now my hips and lower back are hurting me. BTW I take Aleve at night too. The mattress has nothing wrong with it...no sag or indent. Just not working for side sleeping.

Not a good mattress felt great for about a month. I should've had red flags when the mattress arrived too short from my other twin xl and more narrow. Seems like this one was definitely defective maybe? Not wanting to keep it either because my deep sheets don't work on it as well!

I was nervous about purchasing a mattress online. But this mattress has been a great buy. I needed something that would reduce hip and lower back pain associated with side sleeping. After reading other reviews I decided to give it a try and am so glad I did!

Where do I even begin with the Member's Mark Hotel Premier 14" Hybrid Mattress? Let me start by saying the word "Premier" is doing some very heavy lifting in that product name — unlike the mattress itself, which can't even support a small child without swallowing them whole like some kind of foam-padded Venus flytrap. I've slept on air mattresses at 2 a.m. after Thanksgiving dinner that offered more structural integrity than this thing. Calling it a "hybrid" is generous — it's a hybrid of disappointment and regret. Fourteen inches of mattress and somehow every single one of them is useless. My kid sits on it and practically disappears into the abyss like it's a memory foam black hole. The only thing this mattress is firm enough to support is my growing resentment toward Sam's Club. Speaking of which — let's talk about that famous "Satisfaction Guarantee." You know, the one proudly plastered across their website and membership materials? Turns out it comes with a silent asterisk that reads: unless it's this mattress, in which case, good luck and may God have mercy on your spine. I tried to return it and was met with more resistance than the mattress has ever provided my back. Apparently "100% Satisfaction Guarantee" is more of a vibe than an actual policy. So here I am, stuck with a $400 slab of lies, sleeping like I'm suspended over a pit of marshmallows, wondering what I did to deserve this. If you're looking for a mattress that functions as a mattress, keep scrolling. If you're looking for an oversized, overpriced dog bed that will also teach you a valuable lesson about reading the fine print — this is your guy. Would not recommend to my worst enemy. Would recommend to my neighbor who keeps parking in my spot.

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 bought two twins a couple weeks ago (firm for husband and medium for me) for our king size platform. I really couldn't be happier, and my husband likes his, too. We both slept better immediately. Less tossing and turning from him, and I wake up in the same position I fall asleep in, with no extra stiffness/soreness. My only complaint is that when we measured (twice!), the twin x 2 was the correct size according to the chart, but now that they are here, unwrapped, and inflated, maybe the twin XLs would have fit a little better length-wise? Not a big deal for us, though...the foot of the bed is covered in sheets/blankets anyway, so it's not worth time or effort to exchange over a couple inches...but this is just a heads up for others who have different taste in firmness levels and want to try doing the same. Wait for the occasional $50 off and splurge. I think these mattresses are definitely worth it!

Like other people reviewed, this mattress arrived with a defects. On one side it was 4 inches short, on the other side it was 2 inches short. The foam was also misaligned to the base so the coils stuck out 2 inches on one end and the foam stuck out 2 inches on the other end. The cover also fits loose and theres no foam protecting the bottom coils so they pushed through my bed slats. Sam's Club was great about taking care of the problem. They offered a return or replacement. I opted for a return and purchased another mattress. Sam's Club sent out somebody to pick it up for disposal. Some people had good experiences but I'd recommend going with something else.
