All the reviews were great. As I was looking for a firm mattress. One person said they took it back to Sam’s because it was like sleeping on a floor. That’s exactly what I needed to hear. Sam’s delivered it, it better then I thought it would be. If you like it firm buy it.

Loved my full size mattress so I bought the same one in queen size. This queen is much softer and there is less side support than the full size mattress. It still supports well, it just isn't as firm. Also, it took 34 days and a call to the Serta Pro team to be delivered. Honestly think they forgot my order...

Very nice. Takes getting used to, compared to an innerspring mattress. No bounce at all. My back hurt some after the first 2 nights, but once my body adjusted, no problems. It is a little more firm than my personal preference. I am a big guy and I was worried about being hot. So far, it is very comfortable.

I am amazed how hard this mattress feels when I lay on it for the first few minutes each time, then it seems to mold to me. Many mornings, I feel rested, but way up with a sore hip because I have slept on a side and haven't moved all night---as far as I know. Also, Sam's never sent any kind of delivery notification on this item. It just arrived. Ahead of time and before I had closed on the new house. Frustrating.

My husband and I had purchased a Sleep Number bed, but was never pleased with it. We purchased the Serta SleepToGo 12" Gel Memory Foam Luxury Queen Mattress and love it. It is so much more comfortable than the Sleep number bed and way more economical.

We went to the store to shop mattresses to find out they do not carry Queen size in the store. They advised us to go on-line and order it. The mattress that we received has about a 6"-7" spot on the mattress that appears to be a wear mark right out of the box... Will it matter when the bed is made? No, just a bit disappointed that we have to take something that isn't perfect when we buy new and had to wait to get it...

I received my mattress about three weeks ago. We opened the box and there were no instructions on how to set it up. We looked on YouTube and found a video on what we needed to do. It was simple and took no time to do. I’ve read some reviews that say it took a while for the smell to go away but I had sheets on ours within a couple of hours and was sleeping on it a few hours later. I wanted a firm mattress and had to think a long time about a “bed in a box” with memory foam being firm enough for me. I was very skeptical. This is a very firm mattress and I’m very satisfied with my choice. Overall, This is a great mattress for the money.

I owned the exact same mattress for 6 years and it was time to replace. This was advertised as a FIRM and came in a generic box with no markings. there were no "details", warranty, or instructions included to verify the model and firmness, which is odd for a Serta brand mattress and concerning for me. That said, the mattress quickly took on the shape and depth and had zero smell. It just doesn't feel as firm as the previous one I purchased from Sam's 6 years ago.

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.
