Just had our 3rd Sleepsoul delivered we have a gel 3000 on ours my 9 year old has an 800 full double 6 months old and just popping out of it's wrapper another 800 small double anybody doubting these matresses give them chance to settle in I'd say after a about 5 days their plushness is at its best from the un roll I be hoping for some loyality discount when my twin boys come out of their cot beds
