    • Comfortable & Affordable
Style: 10 Inch Size: Full
This product is a quality full size medium firm mattress that is made of gel memory foam & offers comfort & pressure pain relief. The full size mattress is a proper size of 75”L x 54”W x 10”Th & has individual pocket springs with a strong edge support. The mattress arrives rolled up in a super air tight packaging & once you pierce the packaging to open it, the mattress will automatically begin to rapidly expand to its original size but will take about 24-48hrs to reach 100% its size. The top portion of the mattress is made of breathable skin-friendly knitted fabric with a cooling effect gel memory foam & high density foam underneath it for added comfort & stability. The price listed for this 10 inch mattress is in a fair price range for its nice appearance & thickness size but could be a bit more affordable. ... show more

It’s firm and soft all in one! It gives great support and cradles my body as I sleep well. The combination of springs and memory foam make for a legitimately comfortable mattress

    • A bed to soon be used in our new home
Style: 10 Inch Size: Full
We recently purchased the Ruoysun Full Mattress for our guest room in our new house, and it’s been a fantastic addition. The 10-inch hybrid design, featuring gel memory foam and pocket springs, strikes a perfect balance between comfort and support. The mattress has a medium-firm feel, which is ideal for accommodating different guests, whether they prefer a softer or firmer sleeping surface. The pressure relief is noticeable, making it great for people who suffer from aches or discomfort during sleep. One of the standout features of this mattress is its cooling and breathable design. The gel memory foam helps regulate temperature, which is especially important in warmer weather. We’ve had guests sleep on it during both cooler and warmer nights, and it seems to maintain a comfortable temperature throughout. The breathable layers ensure that it doesn’t get too hot, keeping everyone cool and comfortable throughout the night. The pocket springs provide excellent support and minimize motion transfer, which is perfect for a guest room where multiple people might be sleeping at different times. It ensures that even if someone moves around, the other person won’t be disturbed. This feature is a huge plus for comfort and uninterrupted sleep. Overall, we’re really happy with the Ruoysun Full Mattress. It arrived in a box, which made it easy to transport and set up. The combination of gel memory foam and pocket springs offers just the right amount of comfort and support for our guests, and the cooling feature adds an extra layer of convenience. It’s the perfect mattress for anyone looking to furnish a guest room with a high-quality, comfortable bed that everyone can enjoy. ... show more

    • Great full size mattress for teenagers and young adults.
Style: 10 Inch Size: Full
Comfortable mattress. True to the 10 inches it claims. I purchased this mattress because I had family coming to stay for a week and no extra beds. We just threw it on the floor for the week they were here and then I replaced my teenaged son's mattress with it when the company left. The full size mattress fit my two young 20s adult visitors snugly, but for one week, it worked. It's really better suited for one person, which is how it is being used now. The mattress itself if very comfortable and has been holding up well so far. No complaints about it being uncomfortable from anyone that has used it. I did unbox it and let it expand for 48 hours, and it expanded just fine. I am very happy with this purchase. The thickness is perfect for my teenage son, who now uses this in his full size loft bed. He weighs about 120 pounds, and finds the support is perfect for his needs. ... show more

    • Firm and supportive mattress
Style: 10 Inch Size: Full
I am furnishing the guest room with a full-size bed. Upon opening the box, I had the bed to materialize and foam up. The hybrid mattress is heavy, so I set it on the bed frame. After about 24 hours, the gel mattress materialized. I liked that the mattress is firm, reducing motion disturbance. The gel memory is awesome, as it is comfortable and supportive. The pressure-relieving memory form conforms to my body when I am lying down. The firmness of the mattress supports my various sleep positions because I move around during the night. The gel memory foam helps dissipate heat, preventing overheating at night, and that is awesome because the mattress keeps me cool at night. The mattress is perfect for the guest room. Overall, the gel foam mattress is a good value, and the description of the item was accurate. ... show more

    • Comfortable affordable mattress
Style: 10 Inch Size: Full
This full-size mattress is definitely affordable. The price was right as far as comfort goes. I think it’s very comfortable. I will be adding a topper to it because I like extra comfort, but you can definitely use it as it is the mattress in a box. Concept is amazing to me. I didn’t have to have a giant mattress taken a room in my house till until I was ready to use it. All you do is cut it open. It expands right to sleep that night. Amazing. ... show more

    • Comfortable, soft full size mattress.
Style: 10 Inch Size: Full
This mattress consists of 10 in of soft, layered foam and other padding to create a sleeping space that is sturdy, soft, and also comfortable. 10 inches is truly a great size for these new foam-based mattresses. If they get too thick, they almost become too tall and can interfere with bed frames and fitted sheets. Too thin, and you don't have enough padding. 10 in is a good sweet spot with these new types of mattresses. This one provides good sleep quality while also being lightweight, easy to clean, breathable, and good looking, even without a sheet. Overall this is a perfect mattress in the full size. It is mainly meant for one sleeper and designed to displace a person's weight properly. After using it for several days we have found no indentation, no hard spots, no warping of the mattress, and everything stays in place. The fitted sheets do not pop off, which is also an issue with some thicker foam mattresses. Basically this is the perfect mattress and the perfect thickness! ... show more

This mattress was exactly what we needed to replace our old one. The medium firmness provides great support, and the gel memory foam keeps it cool and comfortable. Our guests love it, and we do too! It’s a great option for anyone looking for a restful night’s sleep.
