    • Best paired with a good mattress topper.
Style: 12 Inch Size: Full
This is a hybrid mattress, which if you're not familiar with what that is, it means it has inner springs like a traditional mattress, but memory foam on top to isolate you from the springs. It works pretty well, but obviously it's made with a strict budget in mind, as many mattresses out there are 5x what this costs or more. The comfort is exceptional for the initial cash outlay. However, I've found after sleeping on a few hybrids that adding another layer of memory foam is money well spent. To wit, the best money you could spend would be for a 2-4" memory foam mattress topper to go with this brand-new mattress. It literally makes a budget hybrid mattress feel like a much more expensive option. Amazon sells many different toppers, I highly recommend picking up a good one to go with your new hybrid mattress. You won't regret that decision. It takes up to 72 hours to "inflate", but I found it was pretty much there after 48 hours. If you can sleep elsewhere while it's coming to form, it probably wouldn't hurt, but in honesty I slept on it the first day. The topper helped. The quality is excellent, especially for the price, and you can't hardly go wrong with this if you're looking for a comfy mattress but don't want to spend a bundle. I have no real complaints but definitely recommend a good topper to go with it. 5 stars. ... show more

    • 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

    • 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
