Q : I have purchased 2 Silentnight Posture Firm mattresses, one King size (3 yrs ago) and the other Super Single (1 yr ago). I found that the Super Single size mattress is a lot softer than the King Size mattress even though it is newer. Is there any specific reason for this ? My kid likes to bounce/jump on the king size bed but the mattress can still remain firm whereas the Single size mattress has lost it's firm/support quality and even gives me a backache when sleeping on it.Thanks
