When we set it up it felt like we were laying on something hard, so I unzipped the cover only to find that they had put the mattress in upside down, and we were laying on the coils. I hope that's not what they do for all mattresses. We flipped it over, and rezipped it, and initially it felt comfortable, but by 2nd & 3rd day my lower back was killing me. We will be returning this. I would not recommend to anyone that could suffer back pain.

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.

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!

Absolutely awful. The bed itself is so heavy to move. It gives far too much. This review is being written a month after owning it. I usually give a bad time for my body to adjust. It feels like a marshmallow, no support at all. Some may like a hybrid foam, this is not for us. Worst investment we could've made.

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.

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.

Purchased King Plush Style. Wife is 130lbs and I am 200lbs. She is doing Well. I am feeling Sunk in already. Heavy Mattress. Overall Rate it a C. My hips when im on my back and side go in to far leaving my lower backside uncomfortable. I am 6ft tall so I'm not like im a huge guy. Unsure of this purchase. Maybe Medium would have been better.

I was initially reluctant, but I am pleased with my recent purchase. I have had split king purple 4 mattresses for a while now, but I wanted to switch to a single king mattress. I'm a 180 pound male who likes a softer feel mattress, and the plush version suits me perfectly. It's has just the right amount of cushion to keep my shoulders from hurting for when I want to sleep on my side, and just the right amount of support for when I want to sleep on my back. I caught this with a $200 off sale, and I believe the quality for price is definitely worth it. I purchased a 4 Way Stretch Micro-Knit fitted sheet for this and it stretches, stays tight, and stays put. No cons so far.

Ordered the "medium" version first. We are going to return it and exchange for the plush. My wife is a side sleeper, and I am a back sleeper. So, we're trying to find the "middle ground" where we're both comfortable. I will update this review (or post a second review) once we get the Plush version in. That said, the bed is comfortable and seems to be well made. We've been on it about a month now, and while we do like it, the medium is just too firm. We're 5'7"/5'10", and ~130-170 lbs. Hoping the Plush version is softer. That said, I called Sam's club service number. They are having someone come pick up the mattress. This is great customer service. In the meantime, I have ordered the plush. I'm hoping for the best, but also I am purchasing confidently because of the great customer service I just received.

Bought roughly 6 months ago, full FIRM mattress. Allowed this to "inflate" for 72 hours before sleeping on it. I am 5'6" roughly 200 lbs and tend to sleep on my stomach and back. I rotate the mattress every 4-6 weeks. Measures at roughly 13-13.5 inches after the 72 hr period which I consider close enough to the description. Initially felt it was too soft for me, however I think it matches the "firm" description when compared to other hybrid/memory foam mattresses. So far I don't have an indention where I sleep, but I do think the regular rotation is making a difference there. I would certainly buy this again; I have recommended it to my friends since buying. Only gave 4 stars because it does get a bit warm as the night goes on which again may be par for the course when it comes to memory foam mattresses.
