This is the second foam style mattress that we have purchased. We have the King Serta 12" Sleep-To-Go mattress in our master bedroom, which we really like and have had for over two years (also purchased at Sam's). We wanted to save money on a mattress (queen) for a spare bedroom, so we went with the Members Mark brand this time. It was pulled out of the package yesterday early afternoon, but after about 8 hours of expanding, it still appeared very lumpy. The edges are not expanding much and the mattress appears to be closer to 8-9", not 12" as advertised. I opted to sleep on the new mattress last night to test it out. This morning when I woke up, I felt I was sunken half-way into the mattress. I'm 6' and 215lbs. I've never had any issues with other mattresses in the past. The mattress is VERY soft, nowhere as firm or supportive as our Serta. I will give the mattress another 24 hours before returning it or contacting customer service to get any issues resolved.

Buyers beware! This mattress is comfortable in the center, however mine never formed on the sides. We waited 52 hours to get on it but it never took. Since then I've been trying to get a refund or a replacement on it but sam's refuses to take care of it. They keep saying they need to pick it up before they will issue me a refund but THEY WON'T PICK IT UP. I keep calling over and over and over again to get it scheduled but they keep telling me i have to wait to be contacted. Sam's club online customer service is by far THE WORST customer service i have ever dealt with. For everyday purchases, Sams is great. But if you're looking to make a large purchase with a "warranty" i strongly suggest you buy elsewhere. Sams does not stand behind their product and they make it outrageously difficult to get help.

I bought this mattress after sleeping on a 1k Serta fancy all the bells and whistles and mattress for the last 5 years. I have never slept better in my life. It is a spiritual experience climbing into this bed every night. I have to fight off my children who try to climb in to our bed every night as well. It’s a neat lesson on physics too, during these homeschooling times.

Mattress is decent and firm enough for my back. Was sleeping on an top of the line air mattress previously and it popped. Decided to get this mattress after looking at many others. 7 months pregnant and very supportive. It came right on time. Works for me.

2 months after purchasing this mattress it began to sag in the middle. 2 people sleeping in this bed wind up laying up against each other in the center of the mattress. THEN - since I can't read "fine" print - SAMS CLUB will not allow me to return the mattress because I threw away the box. THEY REQUIRE YOU TO BRING IT IN FOR THEIR 100% MONEY BACK GUARANTEE WITH THE ORIGINAL BOX. I am so disappointed in the mattress and SAMS CLUB. WHO KEEPS A BIG BOX STORED JUST EXPECTING A TRUSTED STORE LIKE SAMS WOULD SELL THEM SOMETHING CRAPPY THAT THEY WOULD NEED TO RETURN IN THE FIRST PLACE.

Husband and I love this mattress. Let it completely fill before judging. It is a plush feel on top with a medium firm feel lower layer. No sinking in. We are both hard to please with mattresses and love this one. I am a side sleeper and hubby is a combo sleeper. Just works in all positions. Very comfortable! Way to go Sam's!

Brought Queen size this 3 weeks ago, mattress is still only 10" not what is says 12" in final size when it expands. Too soft even though the box and Website says Medium . the person next to you can make you role towards them :D I bought 2 other mattress before, i bought King and Twin was not this soft , it was medium as it was stated. liked it so i bought this , could be diffective from manufacturing! not sure. this may go back to store.

I bought this mattress about a month ago, and it doesn’t show up in my order history so I can’t return it. Hmm weird. Secondly, this is advertised as medium firm, if you go to any mattress store and feel what a medium firm mattress is, this is NOT it. This is the plushiest mattress I’ve ever owned. If you’re looking for any level of firmness, buyer beware! Would return but the order is mysteriously missing from my account.

If firm is this soft, I would hate to imagine sleeping on the ultra plush. This mattress is so soft it is ridiculous. softer than my soft old foam mattress. returning as soon as possible. if you like soft mattresses that come delivered in an easy box rolled up- this is for you.

It starts with the unpacking. You will have to unwind layer upon layer upon layer of plastic - just great for the environment. First time I sat at the edge of the mattress I completely sank into it and my legs disappeared in the foam - I am only weighing 170 lb, mind you! Then I tried sitting at the top of the mattress, a large foam cushion behind my back, making me sit up straight for reading - I looked at my feet up in the air, because once again my buttocks sank into this supposedly medium firm sea of foam. I know I am supposed to sleep on this thing, but even stretching out on this soft foam you have to watch out not to suffocate because once again you are going under! the description says only the first layer is soft, well this thing is soft all the way to the bottom of it. Quite frankly, never have seen or laid upon such a piece of junk 'mattress' in my life, and I have slept on many. This thing is going back right away!
