Style: Hybrid Medium 12" Size: Queen
Frustrated by the fluff of mattress store sales tactics, so I looked at AMZ & found this dream mattress!! Goldilocks approved... #justright Order & delivery were a cinch - UPS driver did the heavy lifting. Mattress is packaged well in a tiny box. Make sure you have plenty of space for opening the box & removing the packaging!! Air out for 2-3 days, cover with normal bedding, and enjoy your first good night's sleep. You won't want to leave the bed! 12" is the perfect size & the hybrid construction offers unbelievable comfort. Regular-queen linens fit perfectly. Mattress-in-a-Box is a strange concept till you realize how much sense it makes. Cut out the 'middle-man' and order directly from AMZ Prime. Serta is a classic brand for a reason - hi-quality product for a fair price & years of construction experience. ... show more

I had ordered this mattress a few nights ago, but canceled the morning after because the confirmation said it would be here until next week, but I needed it now. So glad it came anyway. It’s much more what I need. It has a couple flaws though, which I didn’t expect for the price paid. See pics

Got tired of waking up to back pain. I remembered the serta brand growing up. I loved the mattress. Comfortable. Sturdy. Firm but soft. It is what we wanted.

    • Serta for the win!
Style: Hybrid Medium 12" Size: Full
We chose the medium hybrid mattress for our guest room. A medium firmness seems to be a good middle-ground choice when a variety of guests will be using a mattress. Like the medium firmness, going with a hybrid also seems like a good middle-of-the-road choice that will work well for many people, which makes it a good choice for a guest room. While we haven't yet had any overnight guests to sleep on this mattress, I've slept on the mattress myself several times now for testing purposes, and I must say it is very comfortable. The hybrid design offers the best of both worlds as far as a traditional spring mattress and an all-foam one. Because of the springs/coils, it feels slightly bouncier than a solid foam mattress, but the foam is very supportive and I could not feel any springs, lumps or bumps through the dense foam. And of course the medium firmness means it's neither too hard nor too soft. I added a soft topper that is about 3-4 inches thick, so my brain gets the sensation that I am sinking into a cushy, soft mattress, but my old, abused back and bones enjoy the support of the firmer, denser mattress underneath. It's very convenient to receive a mattress delivered to your door through Amazon. It is much easier than trying to find a way to bring a mattress home yourself, and it keeps expenses way down compared to having a mattress delivered through a traditional furniture store. The mattress arrived inside a large box, rolled up, folded and compressed/flattened. The thought of a folded mattress worried me a little, but I shouldn't have worried because once the mattress fully fluffed up and decompressed, there is not even a hint of it ever having been folded. It's really quite remarkable! We brought the box upstairs to the guest room before opening it, which I recommend, because moving the box is much easier than moving an awkward, heavy, wiggly mattress. Even if you don't need to take the mattress up any stairs or a long way into your home, I recommend moving it into the proper room before unboxing it for the easiest experience. Overall, we are very pleased with this mattress's medium firmness, the hybrid spring/foam design, and the experience of receiving a boxed mattress delivered to our doorstep. Serta is a trusted brand that's been around forever and they really know what they're doing. ... show more

Style: Hybrid Medium 12" Size: Queen
I don't replace mattresses very often. The one this replaced was from 2001 and had gotten to the point were I was sleeping pretty poorly, its amazing how much a good mattress contributes towards a great nights sleep! Firstly this mattress is great and was exactly what I hoped for. The hybrid mattress was exactly what I needed but didnt know. I slept so well from night one and really have no complaints. It is really a great mattress and exactly what I hoped for, its soo comfortable! ... show more

This is queen size mattress from the Serta company. It provides form fitting comfort while sleeping. The mattress is part of Serta's "Sleeptrue " series which allows the user to remain cool during the nighttime hours with no wake-up moments feeling stiff or sore. This queen size mattress does not need additional support besides a box spring set and frame. But Serta has a history of making quality mattress products and this speciifc model is another edition to the company's capabilities and skills in bringing you an easy night of a deep sleep. ... show more
