This was a replacement mattress. We had been using the previous Dunlopillo Firmrest mattress for 20+ years and it was showing signs of wear including a slight but permanent dip. We did go to a showroom and try a few different mattresses, but having had Dunlopillo we found that nothing else felt the same. So we bought the same again (only a bit bigger because we had a new bed too). I have slept brilliantly on the new mattress from the first night and am very pleased with the purchase.
