I love this purchase! I was looking into purchasing a Casper mattress at over triple the price of the Sarah Peyton one & I am so glad that I didn't.
I would say, it is on the firmer side for a memory foam mattress (but anything that isn't super fluffy is firm to me) & I do sleep with another 4'' memory foam mattress pad on top...but I like almost cloud like mattresses. This was the perfect buy for me.
I would suggest "airing it out" for a few days. It really smells like foam & plastic. Still, when I am pulling my sheets off to wash, I can smell it a little....but it isn't enough to bother me & once I have my bed made, the smell is gone.
Love, love, love this product!
