    • It’s very comfortable
Style: 12" Size: Full
This at first softer then I wanted but once put on an adjustable base it was just right.

    • Good night’s rest
Style: 12" Size: King
The mattress is just the right firmness for my back. I have severe degenerative disc disease in my lower back so finding a good mattress can be a challenge. After six or so weeks of adapting to the new mattress, I’m able to rest with far less back pain and I’m not as hunched over when I get out of bed. The edges of the mattress could have more support. Overall one of the best mattresses I’ve had in a while. As long as it has some longevity I’ll be a repeat customer. ... show more

    • Use low bed frame with this mattress or you may struggle to get on it.
Style: 12" Size: Twin
High mattress . I struggle a bit making it with fitted sheets. Will have to purchase deeper sheets. Not as comfortable as I expected but I got used to it. Good quality. No odor. Good support in middle. Side of bed not firm enough to sit on comfortably as advertised.

    • Very supportive for back pain issues.
Style: 12" Size: King
This is a very nice mattress. My wife has severe back problems and this really is nice for her to sleep on. It provides exceptional stability and comfort. We really are glad that we spent the money. I will say that we chose the 12 inch hybrid over the 14 inch because it is supposed to provide a slightly firmer support for her back. We look forward to having this mattress for a long time. ... show more

    • Feels amazing
Style: 12" Size: Twin
I tried going on the cheap numerous times. After paying for several mattresses and then disposal fees, it comes down to one thing; you get what you pay for. I love this mattress, it what I have been looking for. There is a little weird part where the corners of the top stick out a little bit, but I decided that isn’t really an issue. After putting the protector and the fitted sheet on, it’s not there. ... show more

    • Great for side and back sleeper
Style: 12" Size: King
Been using a firm memory foam mattress from Sleep Innovations for the last 7 years. After constantly waking up with shoulder pain or back pain I wanted to try a hybrid mattress that was more of medium. So this Seally mattress has been great at relieving those sore areas in the morning and providing proper support. I’ve been using for two weeks now and it’s helped tremendously. The only issue I have is the edges compress so much when you sit on the side. This isn’t a big deal since the main purpose is laying down but I think I would like better if the mattress was in a frame offering a little side support instead of just the rails and box spring I use. The package weighs almost 100 lbs so be sure you have someone to help get it to the room. I unboxed and let sit for the weekend while we were out of town. When returned it was perfect condition and no plastic smell. Be sure you give it a good 24-48 hours to regain its shape. I would rate this 4.5 stars if I could with just a minor issue of the edges. I would still buy again and recommend. ... show more
