This product is a memory foam & latex foam mattress. I don't believe it's a hybrid. I don't think there are coils in it. It comes delivered in something like a 2x2x4 cardboard box. The mattress is vacuum packed in plastic, folded in half, and rolled up. Once you cut it open, you have to let it expand for a few hours, even a day would be good. I would recommend that you don't throw away your old mattress just yet! After opening the new one, let it sit in the garage for 2 weeks prior to using, as the outgassing fumes are terrible and most likely not good for your health. After replacing the old mattress with it, you should run an activated charcoal air filter in the room for a couple months to take out the remaining VOC's that outgas.

Comfortable and sturdy

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.

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".

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.

This is my favorite mattress! I have replaced all the mattresses in my house with this one. I have back and neck issues and sleeping on this mattress is a dream! I don’t wake up with a back ache!! It cradles your body without leaving indentations. It’s not too hot. It’s just perfect for myself and my husband.

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.

This mattress came in a box about 12x12x36. It was rolled up And shrink wrapped tightly. The minute I cut the wrap it began to expand and within an hour I was making the bed and slept on it that night. No smells related to the mattress. SO comfortable- So comfortable.

Shipped well, extremely comfortable, very pleased!

Fast shipping, good price, and mattress is comfortable enough to sleep all night.
