Finally kicked the old innerspring to the curb and went memory foam. Found this mattress on sale for 250 with free shipping and decided to take a chance.
After a surprisingly short shipping time, it arrived. The mattress expanded very quickly, no odor, and we slept on it the same night though we did take the bedding off next day to ensure full expansion. Very firm and supportive, wonderfully comfortable and I was very pleased with the purchase in every way. Wife and I have slept on it for nearly a month now and absolutely love it. For this price my expectations were fairly low, this mattress has exceeded them in every way!
