This mattress is amazing! I have purchased several mattresses-in-a-box in the past, and this one is by far the best. It is luxuriously comfortable but at the same time supportive. It is super thick, so make sure you have deep pocket sheets. Even so, my sheets fit this mattress very snugly, which is another plus, no unsightly sagging or wrinkles! There was no strong smell when I first opened it, either. I highly recommend this mattress, you wont be disappointed.
