I was not wanting to spend hundreds on a mattress as it is for a guest bedroom and I was a bit apprehensive when I bought this one.  However it is a great mattress.  I unwrapped it and of course it was a bit scrunched up and then it began getting bigger and flatter.  It is a firm mattress which I prefer and I think it is a great mattress for the price.  I hope this helps in your decision making.
