I ordered the 12inch full hybrid mattress for our guest bedroom, and it provides a comfortable and supportive sleep surface. The combination of gel memory foam and pocket springs offers a nice balance between softness and firmness, making it suitable for both back and side sleepers. The medium firmness feels supportive without being overly hard, and the memory foam layers contour nicely to the body, helping relieve pressure points. Motion isolation is good, so movements on one side of the bed do not disturb the other side, which is great for couples. The quality feels solid. The materials are CertiPUR-US certified, and the stitching and cover fabric are well made. The mattress has a consistent feel across the surface, and the springs provide reliable support without sagging. In terms of value, this mattress is fairly priced for a hybrid design with memory foam and pocket springs. The 100 night trial provides peace of mind, and overall it delivers comfort and durability that justify the cost. Overall, this mattress is a solid option for a full-size bed, offering supportive comfort, pressure relief, and good motion isolation for a restful night's sleep. The mattress arrives compressed in a roll, so setup is easy just unbox and allow it to expand fully for several hours before use. It takes a bit of patience to reach its full shape, but the process is straightforward and requires no extra tools. In terms of heat retention, the gel memory foam does hold warmth more than standard foam, making it cozy in cooler environments, though it may feel a bit warm for those who tend to sleep hot. Overall, setup is simple, and the warmth can be a benefit depending on personal preference.

Buying a mattress online always feels like a bit of a gamble, but after a full month of sleeping on the Skyhedon 12 Inch Full Hybrid, I can confidently say this one paid off. The 100 night trial took away a lot of the risk, but honestly I knew within the first week that this mattress was a keeper. The medium firm feel hits a really sweet spot. It is supportive enough that you wake up without that stiff, achy feeling, but there is enough give from the gel memory foam layer that pressure points are not an issue. I tend to move around a lot throughout the night, switching between my back, side, and stomach, and the mattress handles every position well. That kind of versatility is hard to find and speaks to how well the comfort layers are balanced. The hybrid construction is where this mattress really earns its price. The pocket springs provide a solid, responsive base with good airflow, while the gel memory foam on top contours to your body and helps regulate temperature. After a month of use I have not experienced any of the overheating issues that can come with traditional all-foam mattresses, which is a huge plus. Motion isolation is excellent as well. If you share a bed, you are not going to be disturbed every time your partner shifts or gets up in the night. The pocket springs work independently of each other, which makes a noticeable difference compared to traditional innerspring mattresses. The CertiPUR-US certification is also worth mentioning for anyone who cares about what they are sleeping on. Knowing the foam meets standards for emissions, content, and durability adds a layer of confidence to the purchase. A month in, this mattress is performing exactly as advertised and I could not be happier with it.

I’ll be honest… I went into this expecting it to be either too firm or one of those “firm but actually not” situations, but it landed in a pretty good middle spot. Setup was easier than I thought, rolled it out and it expanded without any weird issues, so ease of setup gets a check. Once it settled, the firmness felt right, supportive but not stiff, like you’re not sinking in too much but also not laying on a board. The memory foam feel is noticeable too, kind of molds just enough to stay comfortable through the night. Fit on the frame worked out fine, no overhang or awkward sizing problems. Quality seems solid so far, nothing uneven or lumpy, which I was a little worried about at first. It’s one of those mattresses where you lay down and go “okay yeah… this works,” no big adjustment period needed. For value for money, I’d say it holds up, especially if you’re looking for something in that firm range that still has some comfort to it. Overall, pretty happy with how it turned out and how it feels night to night.

This is an excellent quality hybrid mattress. It has a perfect combination of softness and support. It didn't take long at all for it to be it's full height, we opened it in the morning and we were able to sleep on it the same night. It did expand a small amount more but it noticeably. Fits in a platform bed very nicely no need for box spring. Sheets are also easy to get on and they stay in place. It has a nice cooling feel to it it doesn't hold in heat. It was a fantastic price and I'm really happy with this mattress. It is perfect in my daughter's room she loves t and hasn't stopped talking about how much she loves her new bed.
