This is the first review I've ever left but I think it's important and hopefully it will prevent someone else from having problems. I bought this mattress due to back issues. It started out great-for a few weeks. Within the first month it got a very large dip where I sleep that is so bad you can see it when the bed is made. After two months I rotated the mattress and now there is a dip in the new spot. For reference, I weigh 120 pounds. My back is worse than before I got the new mattress. I have only had this mattress for a few months. I have much less expensive memory foam mattresses that I purchased for my children from another company that have held their shape for over 5 years and are clearly higher quality products. This mattress is terrible. I regret ever buying it.

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.

I bought this mattress early 2020 and was fine about 6 months, then started bowing and resulted in horrible back pain. My boyfriend bought the same one at the same time and had the exact same results. Would never buy again and having issues getting refund!

So far I like it. It is more firm than I normally would like, but yet it was still very comfortable. I slept very soundly. Only time will tell if this continues. As far as the height of the mattress, after leaving it unfolded in my living room for 24 hours, then moving it to the bed(the move actually added more height), it now measures 12". See attached pic.

Super comfortable bed. I’ve purchased a king sized before and has been the best bed for myself. Bought this queen sized bed for my guest bedroom and it did not disappoint. There is a distinct smell but after a few weeks it’ll disappear. Would definitely repurchase in the future. Highly recommend.

I bought this exact mattress a few years ago because I needed a firm mattress. I then moved to another state and it was easier to buy a new mattress at my new location - so of course, I chose this mattress. Because of various back issues I had to have a firm mattress. This is NOT the same quality mattress and is quite soft. I put an earlier review indicating that I was suspect since it came is a plain brown box ... but I tried to give it a chance. Well, it is giving me great back pain to continue to sleep on this mattress. With a ten year warranty, what are my options? Will Serta replace it with a FIRM mattress?

We purchased this mattress at our local Sam’s Club 16 months ago. We got it to replace a 10 year old Serta mattress that had been great to us. We read through hundreds of reviews and decided to give it a go for the price point and overall positive rating. We both have horrible lower back pain since getting this mattress and it continues to get worse. There are indentations/slumps in the mattress on both sides where we sleep. I have resorted to sleeping at the top and foot of bed where there aren’t slumps but still wake up every single day with lower back pain. We wanted to love this mattress, but unfortunately we wasted our money and will be replacing it with something of better quality. We trusted the Serta brand but sadly won’t be purchasing another one of their mattresses after this.

Mattress is only 11" and the cover is not fitted correctly

Bed Sleeps good; the boarders of the mattress is too soft.

I bought this mattress for my brother who's 380lbs and he loves this bed so far.
