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.

This mattress does NOT hold ip. We purchased it in September and it is already broken down. It was much more plush than expected, as well. Save yourself the hassle and get a nicer one elsewhere. This one was great for the first few weeks and has two holes where we have slept for barely two months! The motion transfer is awful, as well. Such a disappointment. We are returning it for a full refund, it hasn’t even been 90 days.

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.

I was nervous about purchasing a mattress online. But this mattress has been a great buy. I needed something that would reduce hip and lower back pain associated with side sleeping. After reading other reviews I decided to give it a try and am so glad I did!

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.

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 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.

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.

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.
