Disappointed the first night and every night since...my husband and I bought two XL twins for our Split King bed. We were disappointed our first night but were told to give it 30 days to get used to. Thirty days later we were even more disappointed but then it was too late to return them. I have been complaining every morning since we bought them 2 years ago. They sag in the center, and I'm a average sized woman, not overweight for my height, my mattress sags in the center worse than my husbands. I've added another foam/gel top on top of my pillow top and that helped for one night. Very disappointed. Maybe these are good for kids but not for adults.

I bought this mattress set for my guest room. I have had several guest sleep on it and everyone said it was very comfortable and that they slept wonderful. I would recommend this product and when I get ready to replace my King mattress that I currently have, I will probably go with this brand and type.

A little firm at first but after a little bit of use it settled in and has been a perfect bed for us. Our mattress was way overdue for an upgrade in both size and comfort and this mattress hit both marks while also staying very cool. We love the added room that the king mattress offers and will probably never buy another bed for ourselves that isn't a king sized bed. We also have been very pleased with serta and look forward to purchasing more products from serta.

Two stars because this mattress is well made, but it is so stiff that I find it difficult to believe there could possibly be firmer mattresses. After years of sleeping on our old queen mattress, we were thrilled to be buying a new and larger mattress. Long story short, we are still sleeping on the old, uncomfortable queen mattress and the new Glenmoor king bed remains empty.

My husband and I both have different preferences in bed types. I need more support due to my back injuries but this bed suites as both! Is soft enough for comfort but firm enough for back support. My only complaint would have to be that the middle seems to be dipping in already, otherwise it's a great bargin.

For what you pay this bed should come with a bed frame. The mark up on products is ridiculous and both Serta and Sam's club are wrong for charging that much for no frame. Bed is very plush. Probably wouldn't buy again though. Doesn't feel like the quality is as high as the price. I've owned other Serta perfect sleepers from the cheaper line and I'd recommend those over this.

Serta makes the most durable and comfortable beds without breaking your wallet! As long as you follow the directions that come with the mattresses, they will last as advertised. Our previous Serta mattress finally had to be replaced, and we upgraded to the Glenmore Plush Top, and are very happy with the set for the price we paid.

[This review was collected as part of a promotion.] The Glenmoor mattress is overall a comfortable mattress. I like the fact that I don't feel my husband moving so my sleep is undisturbed. It offers good support and with the pillow top it makes the mattress comfy. It does keep us cooler during the nite. I wake up feeling much more refreshed and with no back aches! That in itself says a lot! I definitely would recommend this mattress to everyone!

After a hard working day, challenged by the everyday battles with the long tailed "dragons" of traffic, crusading putting the employer's company name up high, and defending the family "castle", a man (knight) comes home to get some well deserved rest... on the Serta mattress... confortable, reliable to get some sure sleep and rest, sinking perfectly into the pillow-top without having to fight the uncomfortable springs of other mattresses... Thank you Serta for a certain "knight's" rest. RBS

There is nothing to complain about with this mattress, except the fact that it took me 23 years of my life to realize how necessary having a quality mattress is! Previously, I had slept on generic twin mattresses and never thought much of a bed as a catalyst for my happiness. The Perfect Sleeper Luxury Hybrid proved me wrong! I have never been an individual that struggles to sleep, but this mattress makes sleeping a delightful experience and provides a comforting sanctuary to rest one's eyes after a hard day's work. The cushion is not to soft and not too firm; it would be Goldilocks' delight! I have noticed no change in form since my purchase and am whole-hardheartedly confident that this mattress will serve me well for years to come!
