High quality- priced right
It’s just the right firmness and comfortable and was high quality for the price for 7 year old granddaughter who would never sleep in her twin bed. Sized up to a full and she loves it. She even started reading before bedtime she’s so relaxed.

Soft and suportive
I love this mattress, it is firm but not overly hard and very comfortable. Great product for the price!

So far so good, it seems to be worth the money
The reviews were pretty good, I purchased it for my child and she says it’s comfortable and then I laid on it, it is soft and firm and so very comfortable.

8 inch firm
It’s so thick. I got the 8 inch. It’s firm but it’s still comfortable and soft. But not too soft. It just feels like your body molds into it. I’m happy I bought this and it was on sale too. It didn’t take too long to fluff up either. Like 10-15 minutes

Nice mattress for guests
We had purchased a queen loft bed (from Amazon) and were looking for an affordable mattress for the top bunk. The primary use will be for our grandkids to sleep over though occasionally adult might use it. The bunk bed required a 6-in. mattress and the picture of this mattress had very "square" corners which I wanted. At the last minute, I decided to purchase the 8-in. mattress because some of the feedback mentioned the mattress was not as thick as it was advertised. I'm very glad I made that decision because this 8-in. mattress is in fact only 6-in. thick (perfect for my loft bed). I was somewhat disappointed in how the mattress inflated. If you compare my pictures with the picture from Amazon's website, you will see that the corners do not fully inflate and are rounded. For my purposes, this mattress works very well. The kids sleep well on it and they don't know the difference between a 6-in and 8-in. mattress. The mattress seems to be medium-firm which also works for kids. I would have rate this mattress a 5 because it is very cost friendly, but the thickness is an issue for a anyone who truly wants an 8 in. mattress. It's for that reason, the rating is a 4.

Wonderful Mattress
This bed is THE MOST comfortable bed I have slept on in years. Worth the money and you sink into it. It also supports my back nicely.

Comfortable and affordable!
Once opened let it sit about 10hrs or over night before judging. My daughters both love them, cannot beat this price or comfort. Would buy again, 10 out of 10 recommend

Fine, but wouldn’t repurchase
These are just okay. If it weren’t such a hassle to return them, I might do it. I’ve bought other mattresses on here that were much better quality, but for the price I suppose this is about as good as it’s going to get. I’ve had these for about a month now and they truly don’t expand out to 8”. The pictures of the two mattresses on the floor were about three days out of the packing (which was dirty and left little stains on the mattress, see photo), and you can see it has barely inflated to 5”. The picture of the single mattress on the floor was immediately after I removed it from the packaging. It’s a medium level of firmness, which I like—not too soft and not too heavy for a small lady like me to move around. Not a lot of noise. I’d probably say these are closer to a 3.5 but if you’re in a pinch, these are good for the price and convenience.

BUENA CALIDAD
Tardo solo 1 día más de la fecha de entrega, pero la verdad valió la pena, llegó en buenas condiciones, muy bien empacado y también está muy pachón, me falta aún probarlo, ya que leí que es bueno dejarlo mínimo 1 día para que puedan expandir y alargar su vida útil.

Me arrepiento de haberlo comprado porque llegó muy tarde
Tardó demasiado en llegar. Aunque el producto se ve bien, la verdad la experiencia de compra fue muy mala
