The mattress is great. More of a medium firm, but plenty of give and bounce being a hybrid with foam vs latex. Will update if after a few weeks there are any issues. Ships from the same factory as nectar and the other popular hybrid mattresses. FedEx has yet to deliver a single Sam's club order by the original estimated date. Ever. I would like an option to choose a different shipper.

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.

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.

I researched for over a month before purchasing. BEST PURCHASE EVER! I was waking several times a night hurting in my hips and lower back on my Temperpedic mattress. From night one on this Members Mark hybrid, I did not wake up once hurting. I even slept an extra two hours! This purchase is well worth the money.

Purchased the "firm" version of this mattress a couple of weeks ago. Slept on it for 5 days now. Very comfortable, and the cooling top is great! "Firm" = support and a little give. Definitely not a hard mattress. No harsh smells were noticeable when the mattress was unwrapped. The box was a little beat up but the mattress was not affected. I would purchase again. Melissa H.

This is the 2nd time I have ordered a members mark twin xl mattress from Sam’s. The first time it was the 12” and this time it’s the 14”. Both times I received a mattress that was twin size not twin xl, contrary to what the box was marked as. I returned the 12” and now I will be returning this 14”. You cannot use a twin size comfortably on an adjustable split king bed or frame. It’s awful having the pillows falling behind the top of mattress all night. This mattress also has very little foam thickness on the springs, it’s only 4” thick on a 14” thick mattress. The mattress doesn’t even expand larger than 13”. I have enclosed photos of this. It’s so bad that the mattress cover is huge compared to the mattress. I enclosed photos of the length measurements along the top of the mattress and along the bottom of the mattress. Customer service states that the length is +-1” well this is 74” on the top and 77” on the spring side. I have 3” of space between the headboard and mattress with the bed set to flat and you can see in the photos that’s with the spring side up which is the longer of the sides, so compared to my husband’s side which is a foam mattress it’s a big difference. I don’t know what the other sizes of this mattress are like but the twin xl is awful. The springs are felt as the night goes on which I say is because of the lack of foam. This 14” also has less coils then then the 12” according to the product information for both mattresses. Save your money folks, this is not the bargain it seems.

The mattress was prefect at first but has seemed to lose its firmness in the 5 months I've had it. I purchased the medium but feels more like a soft at this point. Has anyone had this issue with theirs? Is the company willing to return the product for a firm in hopes that it will adjust to a Medium or stay firmer? I'm not a heavy person by any measure so the weight is not an issue.

Bought 2 of these for our new houses' guest rooms. After shopping around for a well priced mattress we chose these. Very pleased with the quality and price. Once out of the box we left them overnight to expand. They are very comfortable to lie on. I haven't slept overnight on them, but I have had a lie down to test them. I would buy them again for sure.

Liked the price slept great for 2 days. The the pain started gradually getting worse 6 weeks in rib pain lower back pain so bad 2 trips to doctor for exrays chiropractor many times. Could be I'm older or wrong firmness or just not for me. Its weird seems soft and hard make it make sense. None the less its going back never hurt this bad on cheap spring matresses maybe my body is like dude you waited to long ive slept on some pretty rough stuff but never had rib pain like this my god never anther hybrid ugh.

If you are looking for a true firm mattress this is not the mattress for you. We’re purchased other memory foam mattresses from Sam’s and have always been very pleased. When it was time for a new mattress I was skeptical of the hybrid mattress but decided to give it a try since one of the options was “firm”. After letting the mattress expand to its full size I was initially pleased with the overall thickness of the mattress. Then I slept on it. I have always had a firm mattress. I would rate this version of this mattress as soft. I verified that my receipt and the box I received all stated that I ordered and received a firm mattress. Unfortunately this will likely wind up being a complete waste of my money and will likely end up in a landfill sooner than expected.
