We can't say enough good things about this mattress and company!! It's perfect for both my husband and I - him a side sleeper and me a stomach/back sleeper. My lower back pain and decreased significantly since sleeping on this mattress and same my with husband's shoulder pain. At first we had the DAWN firm and found it was just too firm for us. We then EASILY sent back the DAWN during the 100 day trail and opted for the DUSK that is medium firm - its perfect!! Would recommend to all family and friends. Cheers to sweet dreams!!
