Bought this a couple weeks ago and unfortunately, it was just too soft for me. I'm a larger guy, 230 lbs 6'1", and a combination sleeper. It was nice for the side position, but very uncomfortable on my stomach, and not great on my back. Fortunately Sam's made the return process easy.

I bought the Serta SleepToGo 12" Gel Memory Foam Luxury Mattress and I have to say it is more comfortable than my previous mattress. However, I paid $700 for it and I expected better quality. I have encountered some of the same problems that other reviewers have mentioned, such as sagging and heat retention. But my biggest issue is that the mattress is not 12 inches thick as advertised. It is only 10 inches and it has not expanded to its full size even after a year of use. I feel cheated and disappointed by this product.

The mattress seems to be decent quality however with some issues. First, it's not 12 inches thick. It barely reaches 10 inches thick and the cover is loose fitting. Second, obviously it never inflated all the way but this is especially obvious in the 4 corners where it's lower than the 10 inches of the rest of the mattress. We spent about $200 more for the 12 inch mattress. Should have saved our money. Stuck now because we got rid of our old mattress. Such a shame because other than the mentioned faults it could have been a great mattress.

This is like sleeping on a table or slab of cement. The foam is too dense for lighter frame people. I feel like I'm on up hard a counter. There is NO PRESSURE RELIEVING points when you sit atop this. To make things even worse, this foam mattress is so hot I believe in spontaneous human combustion now. I bought this a month ago and wake up every morning sore and stiff, and because of covid I waited on the phone for 47 min to get someone who ultimately told me to call local club, which was horrible at customer service for me. I would never recommend this bed, or buying in-club in case you ever need assistance because this 100% Serta guarantee is sketchy if "not bought on-line". I feel the Sam’s Club Member Services AND the members-only Serta hotline Serta Mattress Specialists should have a much better system to assist members than I have experienced.

I though I had researched this mattress enough and expected a "Firm" mattress. It is not firm. All the layers on top make it pretty soft. Also, the fact that it is a foam mattress leaves it with no real structure at the edge of the mattress. So edge lacks support. I have not returned it yet, but am definitely thinking about returning it. I have flipped the mattress over and am sleeping on the "bottom" of the mattress - that actually is reasonably "Firm".

I purchased this mattress 5/6/2017. Within 6 months to a year of owning the mattress, the memory foam began to lose it's integrity by slightly sinking in the spots where you consistently lay. I weigh 110 lbs, so that is pretty disappointing. This memory foam sure does "remember" the spots where you sleep. I am now sleeping in the middle of the bed where there seems to be the best support. Fortunately, my Sam's club is allowing for me to return this mattress with my receipt 4 years later. I should have returned it sooner, but it is such a pain to return such a large item.

(1) Arrived in a large, tall plain brown box. My concern is that Sam's club sold me returned and/or used mattress. (2) Mattress has a stain on one side. (3) Mattress does not feel like the same model SertaSleepToGo that I purchased and enjoyed twice before. The previous mattresses were in a Serta box with convenient wheels. (4) Sam's Club will not accept a return in the store. They are requiring that I stay home for a pickup. So, I would have to take off from work to return the mattress. I am 100% dissatisfied. Heading over to Sam's Club now to request a full refund for my plus membership.

We bought this Serta 12" gel memory foam to go mattress expecting a 12 inch mattress! Is this mattress comfortable...yes! Is this mattress good looking...yes! Is this mattress a good savings right now... YES!! Is this mattress as it states a 12" inch mattress...NO!! I have waited and waited for it to only reach 10" at best. There is a Serta mattress for 50 bucks less right now(150 bucks after sale) that is advertised as a 10" inch mattress. Just buy that one and save yourself from anticipation of getting a 12 inch mattress! That is why I gave it a 4 star rating over a 5 star one. SO basically all the dimensions of each layer specified are not true according to this mattress.

We bought this mattress 1 week ago. Once we opened the mattress it was super firm. first couple of nights were hard to sleep on. But then, me and my husband noticed our back problems where gone. Now the bed feels medium to firm but I don't think it will get any softer. I personally like firm mattresses but this I feel like it was too firm even though it did kind of help with our backs.

This mattress was purchased to replace a similar mattess purchased years ago. We figured being name brand it was a pretty safe purchase. We opened the mattress and gave it two days is a warm room to expand. It only got to 9.5 inches, not the stated 12. The cover was still very loose unlike the mattres we were replacing. We have slept on it for 2 weeks and it is terrible. It's like sleeping on a board. We put a 4" foam topper on it hoping to not have to return it and it's hardly any better. We will be returning and do not recommend purchasing this product.
