those mattress’s are built better unlike the online versions.
Wonder why that would be? Seems pretty perverse to do such a thing.
#4 The reason is the edge support. Online versions have none as they have to be rolled up and put in a box. When you sit down on those bed you sink and soon will have a depression.
If they have springs the mattress will bounce you around with any movement. Others are all foam like latex and memory foam.
