    • Stinks

      The foam mattress itself is contained within a zippered cover and arrived compressed and rolled up in saran wrap, within a manually knotted plastic bag. Is this normal? The instructions on unrolling the mattress indicated that three tabs had to be pulled. There were no tabs. The mattress was just compressed rolled in several layers of saran wrap. Makes me wonder if it had been refurbished. Not happy. Am considering returning the item. On top of this, the mattress really stinks of mold!

    • Good Quality Mattress - would recommend.

      I am quite happy with this mattress. Unfortunately, since I needed a Queen WIDE mattress, I had only ONE option, so I had no choice but to purchase this one. I am happy with it, but not completely thrilled. I think it was a *bit* overpriced, considering the Queen REGULAR mattress of the exact same thickness and brand was $!@# less... seems a bit too much to pay for 6 extra inches, but I didn't have much of a choice! Overall, the mattress is pretty great quality. It is very plush, beautiful memory foam, and there was no strange smell at all, which you sometimes get with memory foam. It is a definite improvement in comfort from the spring mattress that I had replaced, but you *can* still feel the bar in the middle of the frame. BUT - overall, I am quite happy. The shipping time was excellent - it arrived in 2 days!!

    • very comfortable

      This mattress makes sleeping on a sofa bed great! I used it on top of the "regular" (but inadequate) mattress that comes with the sofa bed and together the thickness is the same as most bed mattresses. I could use a fitted queen-sized bed sheet on it and it fits perfectly. It expanded to the size described when taken out of the plastic wrapping, but is a challenge to store when it's not on the sofa bed. It seemed a bit warm to sleep on but not intolerable.

    Questions & Answers

    Get your product questions answered right here.
    • I would also like to know the density of this mattress. It seems to be one of the few 64" wide that I have found.

      • Thank you for your interest in this item. The true dimensions are 72 inches long x 64 inches wide. The weight is 25 pounds and 4.5-inches of total thickness with 1.5-inches of Visco memory foam. It also has a knit cover for protection and the density is unknown. This item comes with a 5-year manufacturers warranty.

    • Are the true dimensions 72 x 64? Also provide some more detail on the density of the core or the weight of the memory foam. And can you provide warranty details? Thank you.
