It's only a few days that I'm sleeping on my new mattress but so far so good!  It fill out quickly and after 2 days was at full 10" even after having slept on it the might I received it.  There was no smell at all which is a real plus since a lot of these mattresses are subject to that issue.  I'm still become accustomed to sleeping on a mattress without coils... I opted for the foam not the hybrid style.  It is very comfortable and my cats are loving it as well
I also love that the cover is removable for cleaning.  I am using my own mattress cover as well but it's not a necessity.  
Wayfair is great offering a huge variety of products (did a lot of reading to make my choice) at good prices and the delivery was great.  Item arrived sooner than promised.  
Will continue to shop Wayfair....very pleased with everything!
