  • 10/10 recommend!
Size: King Style: 12 Inch
We bought this mattress in December, it is now February. It has been very comfortable and is a nice size. It’s not something you sink into, nor is it rock hard. I think it’s just right for my husband and I. I only feel the springs when I really dig my legs onto the perimeter of the bed, and it isn’t enough for me to care. The shipping quality was great and when we unwrapped it, it sprung open and took about 15 minutes to form into itself. I haven’t found the mattress to be too hot nor too cold. So I recommend! ... show more

  • Great for price
Size: Queen Style: 12 Inch
Mattress is comfortable and supports me and my husband, didn’t take long at all to expand but I do recommend giving it a few hours before laying on it.

  • Decent buy
Size: Queen Style: 12 Inch
So the bed is very springy,but definitely supportive. It has lots of bounce cause I almost bounced my tail right out of it this morning!!! 🤣 but I love it still cause my previous but was too soft! I’d wake up and my body would be very sore and I could barely get out of it cause I sunk down really bad! Fir the price I paid it’s good. ... show more

  • Do not waste your money
Size: Queen Style: 12 Inch
I researched and read reviews and finally decided on this queen mattress for my daughter (who has back issues); I slept on it the first night and let me just say that she will not be sleeping on it! It’s awful. You can feel the springs. There is no side support, so even sitting on the side of the mattress you slide off. I’m going to have to buy a 3-5” topper so I should’ve just bought an entirely different mattress to begin with. This was such a waste of money! I’m not happy AT ALL. ... show more
