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.

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.

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.

I purchased the Firm mattress and have had it about a month, and it has really made a difference in my sleep and helped greatly with my lower back pain. I would call it more of a medium firm, the memory foam top really adds to the comfort but there is a firm layer under that which adds great support. Sleeping on this mattress along with an adjustable base and I do not want to get out of the bed in the morning.

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.

I love this bed! I was weary about buying a bed in a bag but decided to give it a whirl. I will never look back about buying a mattress from a bed store. I am pleasantly surprised with how easy and efficient it was to put up. I was able to sleep on it the same night, but it continued to firm up for the next 3 days or so. I bought the firm for my room while my husband bought the medium for his room. I had back surgery about 2 years ago and my old mattress was 11 years old. This is my first time buying a firm bed. Now, the firmness will be a perceived feeling, but it is like a hotel mattress. It conforms to the body but doesn’t sink in. It is perfect for me and supports my back and hips perfectly. The medium also feels supportive but it conforms a bit more to the body and has a bit more give in the mattress. I have no aches or pains on either bed but the firm is more supportive for me and better on my joints. My husband prefers the medium but likes the firm, too. It really is just a matter of preference. Overall, medium is a perfect bed but the firm is more supportive for my condition. I’m very pleased with my purchase

Wow! I was super worried about purchasing a bed online without trying it out. I have to say this is a great bed. we bought the firm version and it is perfect. It has all the features of a bed 30-40% more expensive. The firm bed is perfect for me (side sleeper, 200lbs, 6'5) The part that really sold me is Sam's return policy. They let you return at any time with no restrictions. I didn't return the bed because it was perfect, but I felt sure with my purchase!

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.

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.
