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.

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 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!

We bought two twins a couple weeks ago (firm for husband and medium for me) for our king size platform. I really couldn't be happier, and my husband likes his, too. We both slept better immediately. Less tossing and turning from him, and I wake up in the same position I fall asleep in, with no extra stiffness/soreness. My only complaint is that when we measured (twice!), the twin x 2 was the correct size according to the chart, but now that they are here, unwrapped, and inflated, maybe the twin XLs would have fit a little better length-wise? Not a big deal for us, though...the foot of the bed is covered in sheets/blankets anyway, so it's not worth time or effort to exchange over a couple inches...but this is just a heads up for others who have different taste in firmness levels and want to try doing the same. Wait for the occasional $50 off and splurge. I think these mattresses are definitely worth it!

Not a good mattress felt great for about a month. I should've had red flags when the mattress arrived too short from my other twin xl and more narrow. Seems like this one was definitely defective maybe? Not wanting to keep it either because my deep sheets don't work on it as well!

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 got the medium for my son who's moving out. The mattress itself is super nice and comfy. The top is squishy which is great and what he wanted, but with some firmness. The only issue is that one side does not expand to the height of the other. We keep the smaller side at the foot of the bed. I measured and one part is at 13.5" while the other is at 13", so not quite the 14" advertised. This leaves the covering a little loose. I believe the unevenness is due to it being rolled and the inner part that is compressed the most has been comprimised.

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.

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.
