Very comfortable. Firm. Filled out nicely after opening and allowing to set overnight. Has only been slept on a few times so unsure on the lifetime of the product.

Great price and a very comfy bed! These new hybrids-in-a-box are the best thing ever! We replaced our Sealy hybrid with this and we're VERY happy with it. The brand name beds are pricey and heavy - these mattress in a box deals are really amazing. Even if we have to replace in 5 yrs rather than 15-20, it's still worth it. There is no smell and it's ready to go as soon as you take the wrap off. Perfectly medium firm. Excellent support for side sleepers. Love it!

Intensely good. Hard to imagine but it comes in a box and opens up to a manageable, full form mattress.

I’m already loving this sleep quality for the money spent. It is very comfortable if it’s perfectly on the frame and seems doable.

The previous reviews are accurate. There is no chemical smell on the mattress and it inflates to its full size quickly. The mattress is firm but not hard and good quality. Good deal for the price in my opinion.
