So far so good. I can tell that I am better rested than I was prior to swapping out the cheap amazon mattress I had been sleeping on. Not amazing (I used to have a Casper and that was my favorite), but solid for the price.

great valued purchase

First, we thought it might be a cheaply low quality mattress, on the contrary, our son loves it! He has been sleeping on in for the past several weeks, and has no complaint about waking up with ache and pain like the previous mattress. We fully recommend this Siena mattress for its' affordability and quality.
