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.

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.

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.

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.

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.

Choosing a mattress is a lot of work. We first decided what type of mattress we wanted. We tried out several options at furniture stores and Mattress Firm and realized that we wanted a Medium-Firm Hybrid with cooling layers on top. This Member's Mark mattress was the most affordable mattress that I could find that matched all of our requirements and it is a bonus that it is 14 inches. We bought the medium and we absolutely love it. It may be very similar to the Nectar Hybrid 14 inch. Great job Sam's Club! We hope that more Member's Mark products that are good quality like this one are available in the future. Thank you!

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.

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.

Hotel premier hybrid firm mattress. I purchased this mattress about 5 months ago and immediately noticed it was crooked the foam and coils didn't line up on some of the edges which resulted in one side of the mattress having no coils under the foam and caused it to gave way as soon as you sat on the edge. Husband already fell off the bed twice because of this, but the only reason we kept this long is because it took us so long to look for a mattress in the first place, we live 24 miles away from the store, and retuning it required us finding time and a vehicle big enough to transport back to the store. When you lie on the bed where all layers line up it is actually very comfortable which is why we found this so dissapointing going through the hassle of returning it and looking for a different mattress which we are still in the process of. If i could be garanteed this wouldn't happen again I would probably get it again since it was comfortable, but buying it and having to return it again if it comes out poorly assembled again is just not something I want to deal with.

Don't waste your time on this mattress. We had two more delivered after the first one was faulty, the first replacement mattress being both the wrong size and the wrong model. Turns out both the first and the third were faulty. Neither expanded to the full 14" height after more than a week of inflate time, both were 70" instead of 75". The return/replacement process is a nightmare. A private shipping company, which was terrible to deal with, was dispatched to our house to collect the mattress. The first replacement mattress was a California King instead of a twin. Unfortunately, we did not figure this out until it had expanded partially on my child's bed and partially on the floor. When I spoke with someone about the issue, I was told that my child could sleep on the california king on the floor while we awaited the pickup and replacement of the extremely too large mattress. It was a true delight to try and get a fully expanded california king out of the room, down the stairs, and outside for the aforementioned terrible shipping company to come and pick it up. While awaiting the pickup and shipment of the appropriate size model my child was completely blocked out of her room by the mattress and forced to sleep elsewhere. After the third and final mattress arrived we set it up and let it sit for longer than the 3 recommended days. It is still just 12" high and 70" long. It does not come anywhere near filling the cover and no sheets will ever fit it. It will be going back. Both of my adult children have had great success with other Sams mattress models, but do not get this one.
