Excellent bed for those looking for a firmer mattress
After 8 years of sleeping on a very soft pillow top mattress, I switched to the Kerrington Cushion Firm Pillow Top and I've been sleeping much more deeply. As a 200lb man, I sank into the softer mattress more and would wake with back pain at times. The extra support of the Kerrington has been great as a side sleeper. However, my wife, who is much lighter, preferred the softer mattress. She isn't really heavy enough to be comfortable with a mattress this firm, so she got a mattress topper for her half of the bed.
