We desperately needed a new mattress for two adults and two dogs. We are larger people and sleep with 60 lb and 12 lb dogs. This mattress is supportive for all the weight it carries from us. We got the medium so we could feel the support but also a touch of plush. Better sleep days are ahead for sure. We have been sleeping on it for about a week and my body is already feeling much better. I have arthritis and my stiffness is much improved so far. As for the unboxing, it was so simple. We opened the box and took the plastic off. The mattress looked and smelled clean. We allowed it to rise and had zero issues with it not being true to size. just buy it already!

If you buy the Ultra Plush, expect a SUPER SOFT mattress. In fact it is so soft, it feels like it is actually hurting rather than helping since there is virtually no support. We like a plush mattress but this is nuts. When you lie on it, and we are not big people, from the side you can only see 80% of us. Medium firm is probably the best. The other issue is sheets staying on. The cover is incredibly slick and the sheets slip off with ease. You will need a zip-on mattress cover that has some friction to keep the sheets from slipping off the corners. All it takes is getting in the bed and a corner will come off. We have the right sized, deep pocket sheets (from Sams). If your weight is in the 100 to 120 pound range, you may not sink like a rock. An average adult (I weigh 190), I am in a hole. This one is going to being returned.

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.

We purchased this mattress in Decembrr 1st, specifically because Sam’s Club stated it would arrive before we left for a month-long vacation. That turned out to be completely false. When we realized the delivery would be late, we attempted to stop it, but Sam’s Club’s customer service was an absolute nightmare—outsourced to a call center where communication was difficult, and in the end, they were completely useless. No surprise there—Sam’s Club’s delivery service is notoriously bad. Major Sizing & Build Quality Issues When we finally set up the mattress in January, we immediately noticed serious problems. It’s not even a true king size—it’s 3 inches too short and 1.5 inches too narrow. On top of that, the coil springs were sticking out on the ends and sides, making it uncomfortable and even painful to get in and out of bed. It feels like they forgot to add the edge band, making this mattress look and feel cheap and poorly constructed. False Advertising – NOT a Tempur-Pedic Alternative Sam’s Club advertises this mattress as comparable to the Tempur-Pedic Adapt Hybrid ($3,200 retail price)—but that’s completely misleading. My wife and I went to test the real Tempur-Pedic in-store, and there is absolutely no comparison. The Sam’s Club mattress lacks the comfort, support, and durability of a high-quality mattress. It’s just a cheap knockoff designed to trick buyers into thinking they’re getting a premium product. Deceptive Business Claims Even worse, Sam’s Club’s ad claims this company has been in business for 140 years—but in reality, they’ve only been making mattresses for a few years. This is just another marketing gimmick meant to mislead consumers. Final Verdict: A Complete Waste of Money This mattress is low-quality, falsely advertised, and sold at a price that tricks people into thinking it’s high-end. Between the delivery issues, false claims, and poor construction, this has been a frustrating experience from start to finish. If you’re considering buying this mattress from Sam’s Club—DON’T. Save yourself the hassle and look elsewhere.

The plush mattress is like sleeping on a marshmallow. You totally sink into it. No support whatsoever. And I like a softer mattress. But not this. Also, there is NO reason for it to be 14 inches thick. Making the bed is a nightmare and keeping some expensive deep pocket sheets on it is impossible. Have had the mattress on a guest bed just a few months. Will be putting on the curb for garbage pickup soon.

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.

This is my initial reaction; we chose the Queen Firm - I was worried about the firmness (specifically that the mattress would be way too soft). The rating scale of 1-10 seemed subjective (Medium was 5-6 & Firm was 7-8). Our old traditional mattress was called ‘Firm’ by Sealy and it felt like lying on a brick while sleeping even though there was a cushioned feel if you pushed down while standing next to the bed. My wife and I are in our 60’s and have developed shoulder pain recently from sleeping on that mattress. The Members Mark Hybrid ’Firm’ is perfect … stable but like a pillow-top topper that gives for comfort and support but gently firm below. In the box it was very heavy but unboxing was easy. The air rushed in quickly when vacuum seal was opened and it came into shape quick. Two of the corners aren’t perfect but it’s not a glaring defect - just a small folded and puckered spot. It’s going to be covered by sheets and blankets so it is a big non-issue. The cooling top is nice. I reasoned that we’ll spend 30% of our lives on this mattress so it will be worth the investment to be comfortable. If our sleep experience isn’t good then I’ll update my review but so far - I think this mattress and firmness choice will turn out to be perfect.

Highly recommend for anyone who has never bought a new mattress and is on a budget. We did not want to spend over $1000. I did some research and tried a mattress that we did not see or lay on in person. The reviews did not lie. It is so comfortable. Definitely feels like the higher end hotel beds we have slept on. It arrives in a box. We took it out of the box and placed it on the bed before unwrapping the package. Let it sit for a good 6-8 hours then we slept on it that night. It is a good firmness. Not too hard and not smushy. It is great. My husband overslept after the second night and said it was my fault for buying such a comfortable mattress. I'll take that as a good thing.

solid, but forms to you, very comfortable.

It said is medium but is really sof
