we just love this, it is not too hard or soft, and NO overheating at night from this set. I did get the higher box spring, (9" ) and it is quite high, however with a bad back, legs, and knees I love that it is sooooo easy to get out of this bed in the morning. My weight is 340 lbs, and I am 5'5" and my husband is 5'5" weighs 160 lbs, we have no problems with this set shifting etc, we each have this set (due to my handicap needs), and he has bad hip and knees too, but both of us are very happy.

We just received this mattress yesterday and we are pleased with our first night's sleep. We replaced a 4 year old Tempur Pedic that we hated. It was too hot and my boyfriend sunk in, could not roll over easy. We went to popular mattress store to try out similar mattresses to get an idea of the firmness of this model. The price is great as we looked on websites and went to competitor stores, it was very difficult to find a king size mattress under $1000 w/free shipping and free pick up of the old mattress. We received the bed 11 days after order. We could have received it 2 days earlier, but it was a weekday and we wouldn't be home to accept the delivery.

Bought this mattress couple weeks ago for guest room. Looks very comfy but sits so high on 9" box spring. Club did not have a Serta "low profile" box spring. Afraid may be unsafe for young children or elderly to sleep on. Not sure what to do; may have to return if I can.

I purchased this mattress at Sam's Club and I thought like others that it was a plush mattress. It is not a plush mattress, it is Hybrid mattress and all Hybrid mattresses are a little firmer when you first purchase them.. If you read the label on the side of the mattress it says 866 custom support FIRM individually wrapped coil system. Which means it has firm coils inside of the mattress with a memory foam top. It sleeps well, and it will break in after you use it over time. Mattresses today cost as much as a good pre-owned car, so for the money and Serta quality, this is a great deal especially with the instant $130.00 off the price. If you are looking for a good mattress and do not want to break the bank, this is the one to buy. You get a great Serta quality mattress, made in the USA, and it's a 14" thick pillow top mattress. After a short time of using it, the mattress will break in and be more comfortable to your liking. All good mattresses are a little firm when you first buy them, but after a little time, it will feel a lot better and softer.

I love how you don't feel the other person moving around on this mattress. My old mattress was starting to cave in the middle and this mattress has been a welcome change. The mattress is a little firm, but comfortable. The only downside is that it is pillowtop so you can't flip it over. But, then you have the comfort of a pillowtop.

I bought this for wife mainly. She says she has had a better sleep and getting into rim sleep (being able to dream). I have had seven back surgeries and I find it has a great FIRM support, but with the soft pillow top it is comfortable. I always had to use an egg crate mattress over our old mattress. Great value, and with 866 coil springs I am sure it will hold up for years to come. People need to research and know how they sleep before blaming the Mattress for being firm. If you sleep mainly on side you may need a mid-firm mattress or maybe a soft mattress.

I loved this mattress set when I first got it. Delivery was quick and professional. They even took my old mattress set when they left. The issues started about 2 weeks later when I noticed my mattress sagging in the middle. On further inspection the box spring broke from regular use and caused the mattress to sag. I had to get a replacement set. I also had to get a base that has slats to better support the bed since I don't want to run into the same issue again. The mattress is what I was looking for just disappointed that the box wasn't/isn't better constructed.

I absolutely LOVE this mattress. I have an extremely bad back, and this provides the comfortable support I need. I rest ugh better, and my pain has lessened, ..I encourage you to buy. You won't be diisapointed.I'd give it a ten if that were an option!

We just bought it online on last big Friday sale. My husband got a pain from sleeping on too soft mattress so we normally sleep on the flat sheet on the floor. Yesterday night the mattress just arrived and today my husband says he felt no pain on his back at all. For myself I love the balance between how firm and how soft of this mattress. Recommended to have one!

I only gave this a 1 because I couldn't give it less than that. We tried this in store and it was soft. However, the mattress that was delivered to us is rock hard. It is difficult to sleep and leaves pressure points. Buying this mattress was a terrible mistake.
