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.

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 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!

Wow! I was super worried about purchasing a bed online without trying it out. I have to say this is a great bed. we bought the firm version and it is perfect. It has all the features of a bed 30-40% more expensive. The firm bed is perfect for me (side sleeper, 200lbs, 6'5) The part that really sold me is Sam's return policy. They let you return at any time with no restrictions. I didn't return the bed because it was perfect, but I felt sure with my purchase!

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.

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.

Very comfortable mattress. I will be buying more of these soon!

Not as firm as I was expecting. I ordered the firm but the mattress is more like a medium firmness.

It said is medium but is really sof
