    • Super soft ! More soft then firm ! (Sinks when sat on)
Size: Full Item Thickness String: 14 Inches Set name: Hybrid
Very comfortable. I love it. It’s just my style of bed I imagined! It is very very soft and flexible more than I’d say firm! Quality is amazing, but if you prefer firm mattress I would definitely suggest something else! I absolutely love this bed for the price.

    • Peaceful sleep despite the smell
Size: Queen Item Thickness String: 14 Inches Set name: Hybrid
I love my bed. But it has an odor to it that I need to know how to get rid of. I love the height, the color and it was easy to put the the frame. Would I buy it again yes but not until there is a solution to the smell.

    • Okay for guest bed
Size: King Item Thickness String: 12 Inches Set name: Hybrid
Not as much support as I thought. There’s a weird smell still lingering on it. Was easy to unbox and unravel. Can feel the springs. “Memory foam topper” is too soft and you sink right into the springs. This is a short term mattress so it will work for now but would not use this as a long term option (would need an additional topper). Could see it as a good guest room bed. ... show more

    • IN LOVE WITH MY MATTRESS
Size: Full Item Thickness String: 14 Inches Set name: Hybrid
It feels amazing . Might be a little soft but that’s perfect for my back . I highly recommend. It was easy to set up, I didn’t have to do much honestly . Once I took the plastic off it immediately inflated. It was the perfect fit for my bed frame, and it’s always cool. It makes sleeping addictive , with especially how it supports my back. Would definitely buy again ... show more

    • Overwhelming stench
Size: King Item Thickness String: 14 Inches Set name: Hybrid
We were excited to receive our mattresses. Unfortunately as soon as we opened the package this overwhelming stench of fermented fish filled our room. It’s been several days now and the smell is still so overwhelming ( we have to leave our windows open ) that we had to move the mattress out of our room and into our garage. Hoping it will air out so we can use it , as we paid a lot for it. Also it is NOT 14” thick , which we paid for the 14”. Wish we could give it a better star review but we can’t. VERRY DISSATISFIED with the mattress . ... show more

    • Confortable
Size: King Item Thickness String: 12 Inches Set name: Hybrid
This mattress was a great purchase for us. It was delivered quicker than expected and had little to no odor. This is one of the most comfortable mattresses I have owned. It has the right amount of support for someone with a bad back.

    • Very soft mattress
Size: Full Item Thickness String: 14 Inches Set name: Hybrid
It’s comfortable, I bought this for my toddler. When I sit on the edge it goes all the way down but if I lay on it, it doesn’t sink too much. The softness is probably best for kids and not adults. Otherwise it’s good. I wish it was more firmer just a tad.
