Problems with a mammoth bed

Hi had a mammoth bed, pocket 27 from furniture village, for about a month now, my husband & I suffer from arthritis & our aches & pains have become much worst, I am having to see a chiropractor because of this , sleep on my side & feels like springs digging in, mattress very soft, is this normal for this type of mattress, last bed was a Harrison which was very comfortable, wish I could have it back !
