I was leery to purchase a mattress online without trying it out, but after reading multiple mattress descriptions, I felt I found the one! We just purchased a bed frame from Wayfair and wanted to follow-up with a mattress. Wayfair really does offer good pricing if you are looking for online products. This mattress stated it was chemical free, or almost chemical free, I do not recall, but reading specifications helped make my decision. Our son wanted something medium to firm, and this mattress provided enough height for the bed frame. He loves his bed- it's comfortable and fits his style perfectly. The mattress arrived rolled up and packaged, was easy to unpack, and was to its "normal" expanded size in no time. I would recommend this brand to anyone although my daughter thinks it's too firm for her liking. She is next on the new-bed-purchase in our household!
