Perfect comfort

It feels great. Not too soft not too rough!

This mattress is small

This mattress is smaller than my last king size mattress. I will see how it holds up.

Uncomfortable

The mattress was okay for about 6 months but then became very uncomfortable.

Softness & hot

So far, I wish that I bought a firm and it seems like I get really hot in the bed. I'll give it a chance.

Verified Purchase

Not as expected

It is much softer & higher than expected. It was delivered to my neighbor’s, at the bottom of 6 steps …it’s VERY a heavy. Would be nice if when unwrapped it was right side up not upside down.

A reliable mattress

[This review was collected as part of a promotion.] This sprung to its full size in a matter of minutes. It has a cushy top but nice support underneath. It does fit slightly small for the bed frame size but not enough for it to matter. It seems like a quality piece for a reasonable price.

Comfy

[This review was collected as part of a promotion.] It is so extremely comfortable. The perfect amount of support not too firm not too soft. I have just the mattress only no spring box or bed frame and it’s the perfect height for my cosleeping baby to get down from

Best mattress ever

This mattress is the most comfortable mattress I've EVER had. I lost my last one in a house fire from the soot damage. I HAD to have the exact same one and searched so long to find the exact same model to replace it. Not too soft and not to firm. It's a perfect balance, good support but also soft and comfortable.

The Mattress is Perfect!

Simply amazing! Who would have ever thought a mattress in a box would be fabulous??!! Not only is the mattress beautiful, but the support is wonderful. Our house is divided in the soft/firm camp and this one makes us both happy. The mattress doesn't run hot (a big concern for me!). Truly never thought we would get a mattress without trying it out first in a store, but REALLY this mattress is GREAT!

5-Star Mattress Review: Perfect for My 19-Year-Old

We recently got this mattress for my 19-year-old son, and it has been an absolute game changer! He’s been raving about how comfortable it is, and I’ve noticed he’s been sleeping much better since we made the switch. The mattress perfectly balances firm support and soft comfort, giving him a great night's rest every time. As a college student, he spends a lot of time sitting and studying on his bed, and this mattress has been incredibly durable and supportive for both sleeping and lounging. He loves that it doesn't sink too much, and the motion isolation has been great—no tossing and turning wakes him up anymore. Overall, we're super impressed with the quality and comfort of this mattress. If you're looking for a reliable, comfortable bed for a teen or young adult, I’d highly recommend it!
