    • Comfortable and Supportive Mattress for the Price
Size: King (U.S. Standard) Set name: 12 Inch
I’ve been sleeping on this mattress for a little while now and overall I’m really happy with it. It came compressed in a box, but after letting it expand, it filled out nicely. The firmness is probably my favorite part. It’s not too soft and not too hard. It feels supportive underneath but still has a comfortable, softer top. I’ve been waking up feeling much better than I did with my old mattress. I also like that movement doesn’t transfer too much. When my husband turns over or gets out of bed, I don’t feel the whole mattress shaking. There was a slight new mattress smell at first, but it went away after airing it out. For the price, I think the quality is very good. It feels comfortable, supportive, and more expensive than I expected. So far I’m very satisfied with it. ... show more

    • Great price for a good mattress
Size: King (U.S. Standard) Set name: 12 Inch
Great price for a good mattress. We got the 12 inch king size hybrid medium plush mattress and, so far, so good! Obviously for this price you cannot expect a Cadillac of a mattress but it has surprised us so far. It is the first one in years that I wake up without back pain. I agree with the other reviews that the ends sink when you sit on them but it has been great where we sleep on it (and we use it as our primary mattress). We felt it was spot on with the firmness. ... show more

    • Amazing Sleep Upgrade, This Hybrid Mattress Delivers Great Comfort and Support
Size: King (U.S. Standard) Set name: 12 Inch
I could not be happier with my new SleepSphere King Size 12‑inch hybrid mattress. Unboxing was simple; it arrived compressed in a box and fully expanded within hours right on my bed frame. The medium‑plush feel strikes the perfect balance, soft enough for comfort yet supportive so I do not sink too deeply. Thanks to the individual pocket springs and SmartS Coil Tech, motion isolation works incredibly well. My partner tosses and turns at night, yet I barely feel any movement, which has drastically improved our sleep quality. The Euro‑top layer brings wonderful pressure relief for my shoulders and hips, easing the aches I used to get from my old mattress. It is reassuring to see it is CertiPUR‑US certified, meaning safe materials without harsh chemicals. After several weeks of use, it holds its shape nicely with no sagging. This is an outstanding mattress for anyone wanting restful, uninterrupted sleep. ... show more

    • The plush mattress is a firm, coil feeling disappointment
Size: Queen (U.S. Standard) Set name: 12 Inch
The plush is still a firm, coil feel. It’s a hassle to have to go through the return process immediately for a product this size. If you a looking for a soft, pillow top-like mattress, this is not it.

    • A Good Buy Worth The Money
Size: King (U.S. Standard) Set name: 12 Inch
The mattress was wonderful. The bed was easy to set up and was nice and firm. I did have a problem with the company that was supposed to pick up the used mattress. I had a pick up for today and was told that my number was not on file and my delivery pick up address was to far for pick up today. I took off work and now I have to have a pick up rescheduled for tomorrow. The company should have reached out the day before to confirm number my contact number. ... show more

A high quality mattress. I would rate it at more of a medium-firm mattress which is what I was looking for without trying it. I would purchase again for my other bedrooms if I needed to in the future. The packaging was great and wasn’t too hard to unwrap, it was vacuumed and all I had to do was to let air in and it expanded. The picture showed what it looks like after two days of opening. ... show more
