  • Full Size Mattress
Style: 12 Inch Size: Full
I ordered this 12-inch Full Size Mattress for my daughter's bed, and it has proven to be an exceptional addition. This hybrid mattress combines advanced gel memory foam and individually wrapped pocket springs, striking a perfect balance between comfort and support. With a medium-firm feel, it provides the ideal level of firmness for my daughter, who tends to prefer a mattress that supports her body without feeling too rigid. One of the standout features of this mattress is its cooling and breathable design. The gel-infused memory foam is specifically engineered to help regulate body temperature, which is crucial for my daughter, as she frequently experiences hot flashes. I've noticed that the mattress effectively dissipates heat, maintaining a consistently comfortable temperature throughout the night. Additionally, the breathable layers allow for optimal airflow, ensuring that she stays cool and comfortable as she sleeps. In terms of comfort, the mattress has really excelled. It offers remarkable pressure relief, which has made a noticeable difference for her, especially since she often suffers from back aches and discomfort during sleep. The combination of memory foam and pocket springs offers targeted support for her spine while contouring to her body's natural shape. So far, the mattress has held up exceptionally well, showing no signs of sagging or discomfort after several weeks of use. I am genuinely pleased with this purchase, and I believe the thickness of 12 inches is just right for my daughter, providing both softness and support without being overly plush. Overall, I couldn't be happier with this mattress—it has transformed her sleep experience for the better. ... show more

  • Balance Comfort and Support
Style: 12 Inch Size: Full
After too many nights on a mattress that felt like a medieval torture device, I took the plunge on this 12-inch hybrid. Between the gel memory foam and pocket springs, it hits that sweet spot—firm enough to keep my back from staging a protest, but soft enough that I don't feel like I'm sleeping on a plank. Unboxing was a trip—came compressed in a box, and watching it expand was like witnessing a magic trick. Took about 48 hours to fully puff up, but the wait was worth it. Now, after a long day of wrangling hair at the salon, chasing my 6-year-old, and dodging the three cats underfoot, collapsing onto this mattress feels like a reward. It's breathable, so no overheating, and the motion isolation means I don't get jostled every time my husband decides to reenact a gymnastics routine in his sleep. If you're in the market for a mattress that balances comfort, support, and the chaos of family life, this one's a solid bet. ... 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

  • 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

  • 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
