Hi baronck,
I can only speak to the quality/value of the mattress you are considering which is made by Primo International which is an importer of mainly lower quality Asian mattresses that tends to use low quality/density memory foam in their mattresses. You can see it here at Wayfair as well.
This mattress uses 4.5" of low quality memory foam (less than 4 lbs) and is also not CertiPur certified and doesn’t meet the guidelines I would suggest using when purchasing a memory foam mattress … particularly at this price.

I would avoid it for several reasons including that it’s not particularly good value, because the quality of the upper layers (the weak link of a mattress) is low, and because it uses Asian memory foam that is not CertiPur certified.
