We bought the king size mattress to replace our 12 year old very expensive (but comfortable as well), Tempurpedic. Construction of mattresses have improved so much that you no longer have to drop thousands to get a firm good nights sleep. My husband set this up the evening we received it. Out of the box and on the bed. We were asleep in no time. We have been sleeping on it for a month and it is firm. DH is close to 300 lbs and 6' tall. Neither of us sink into the bed. It is incredibly supportive and we are sorry we didn't replace our old worn out mattress sooner. We bought this be on sale for $399 during the Sam's club event. Because of the deal and the reviews, we also bought a Queen size to replace on of our guest bedroom's mattress. This sleeps just as comfortably. We have tried both. TWO fine quality superb mattress for under $800?! Unheard of!! Don't think twice about this mattress. You will not regret it!

Needed a new mattress for the guest room. I knew Serta has great products so I jumped on line to Sam's club. In minutes I found what I needed. Received the mattress in less then a week. Put it on the bed and it was just what we needed. Saved money and Time. You can't beat Serta and Sam's price and service.

I like a firm mattress but also comfortable. This one has been good thus far. I have some issues with my shoulder and hips. My arm has a tendency to go numb during sleep. Since I have had this mattress I have noticed that I do not have to prop myself up to get my shoulder off mattress. I am not sure if it is a back related or shoulder related issue but I haven't had the problems since I have been sleeping on this mattress. I would say "thumbs up!"

I replaced a old spring mattress with this Memory foam one. I have been watching the development of the foam mattress for a while. I was always worried about the heat and the mattress being too soft. This mattress has multiple layers to keep it cool and is firm. I have found that I do not wake up in the night or toss and turn as much. It gives great support for your back while contouring to your body on your side. I would definitely recommend this mattress.

I purchased this mattress solely because of the rating it received from consumer reports (and the reasonable price). It is advertised as a 12” mattress, but mine is barely 10” after two weeks. I’m a side sleeper and it was way too firm for me, so I purchased a 3” memory foam topper. So far, after only two nights, It is much better, but I will reserve final evaluation for a month or so.

In store, presale ,the mattress was in a wheeled box with a handle for easy handling. I ordered on line and it was to be delivered i 3 weeks. the next week it was delivered in a non wheeled box. I flipped the box end to end like a workout video of a body builder flipping tractor tires up a stairs to my bedroom. No instructions on or in the box of how to unpack it, care for it or the warranty. We pulled it out of the box and carefully cut the plastic bag and it inflated... fully after 4 hours. No care instructions in the box. Sams referred me to Serta. Serta said Sams has the instructions. Sams sent me back to Serta. Serta said Elite Comfort Solutions ( the subcontractor that makes and ships the mattress) may be able to email me care instructions and warranty. No response from them. The mattress is firm and after a week developed swales on each side we sleep on.

It’s a good mattress. It is not as firm as I imagined it would be, but it’s far from terrible. I have chronic back issues and have found that firm mattresses are the most pain-relieving for me. This one does have some “give” but not too much. It’s not rock-solid like some other firm mattresses.

I bought thsi for our son's bed to replace a matress that was a hand me down (20yrs old) He says it it very good to sleep on and likes the firmness but softness that it gives him when sleeping. He says he sleeps in one spot now and doesn't toss and turn. I'm glad he really likes it

We are so glad we bought this mattress!! After looking at several different mattresses we decided on the Serta Sleep To Go and are very happy with our decision. It took a couple of nights to get use to the mattress but we've had it about a month now and wouldn't give it up. We both woke up with backaches every morning with our old mattress and now we wake up feeling great!!! Love this mattress;)

This mattress is HARD. The top layer of foam is nice, it gives when you lay down. However, the lower layers of foam do not give as well. If you are a vampire sleeper (one that never moves) you will be fine, as the bed will form to you over time. If you are an active sleeper (one that moves at all, or changes positions frequently) this is not the bed for you.
