I love this mattress topper.  I ordered a new mattress from a Big Box store for a ridiculous price (cheap) but it was a Serta  It did not have the pillow top to it and I was afraid it would not have a cozy feel.  This addition is just what the mattress needed.  It arrived folded up in a box, but when I opened up the plastic it just unfolded easily.  I let it sit for a day or two.  It is very comfortable!!!  You cannot beat the price.  I did not wash it as I feel my washing machine could not handle the size so not too sure how it will wash up.  The reviews state it washes just fine!!   Thank you Wayfair!!
