Purchased my mattress in December 2010 replacing a very worn set that has gone way past its time. I have always had a firm mattress and I have back problems. When I talked to the owner, who is very informative on mattresses. He explained the different types and what was best for my needs. The prices were great compared to the larger stores the mattresses are covered by the manufactures warranty. My mattresses came out to half the price of what I would have paid at one of the mattress chains. I now refer my friends to Sleep World.
