  • It's perfect, comfortable, i recommend to buy this
Size: Twin Style: 6 inch Pattern Name: Firm
I got this mattress for my 10 year old son and it’s been a really good . It came in a box and expanded pretty quickly once opened. No smell, that i like it.The mattress is medium firm but still has enough softness from the gel memory foam so it doesn’t feel hard. My son says it’s comfortable and he sleeps through the night without complaining about his back uncomfortable. It feels supportive enough for a growing kid and holds its shape well so far.it's has zipper cover so esy to wash .not make any noise Overall, solid mattress for the price and great for kids. ... show more

  • Perfect balance between softness and firmness
Size: Twin Style: 6 inch Pattern Name: Firm
I bought this mattress for my 6-year-old son, as he was no longer sleeping well on his previous one. My son now sleeps much better and rests soundly through the night. Overall, I think this is a great option for a child's room; it is a comfortable mattress that strikes the perfect balance between softness and firmness. It arrives in a box, vacuum-sealed inside a bag; upon opening it, it immediately begins to expand. It has no strong or unpleasant odor, and its thickness is ideal for a child's bed. It is affordable, so it is well worth the price. ... show more

  • Best mattress I've ever had and the price makes it unbeatable.
Size: Full Style: 10 inch Pattern Name: Firm
Incredibly comfortable. My old mattress is a firm but after all the years of use, it was sagging in the center. So it was time for a new mattress and just wow. I forgot what a firm mattress actually felt like. This one is so comfy and has absolutely no sinking or soft spots. It's also so much lighter than my old mattress and putting the bed spread on is so much easier now. I honestly wasn't sure if a mattress this cheap could be as good as the big time brand names but I am so glad to be wrong. This is the best mattress I've ever had and the price is unbeatable. ... show more

  • Nice FIRM mattress
Size: Queen Style: 12 inch Pattern Name: Firm
I had enough of the handmedown mattress of my inlaws and was searching for a firm gel/foam mattress. It came within 2 days, and when it arrive it was rolled up in a box. I cut open the box and it popped right out. It set very nicely after taking it out of the plastic, took only a few hours for it to puff up. My husband helped me put it on the bedframe. It's nice and firm, that I wake up refreshed, no joint pain, allaigns my spine, no funky smells, and was very cheap for the quality! I love the gel/memory foam as I don't have to worry about the springs or coils which can be dangerous! ... show more

  • very soft!
Size: Full Style: 8 inch Pattern Name: Firm
This mattress ended up being way better than I expected. It came rolled up in a box, popped it open, and it expanded pretty fast. There was barely any smell, which was nice. It’s medium-firm but still really comfortable. Supportive enough that my back feels good in the morning, but not so firm that it feels stiff. I don’t feel pressure on my hips or shoulders, and it doesn’t make you feel stuck in the foam. It also sleeps pretty cool compared to other memory foam mattresses I’ve tried. I like that it’s fiberglass-free and CertiPUR-US certified too — good peace of mind. Overall, great mattress for the money. Works perfect for everyday use or a guest room. Would buy again. ... show more
