I placed this bed topper on my son's bed. His mattress is an older hand me down that while comfortable felt a little springy. The memory foam topper transformed his old mattress into new! His bed is so comfortable now. You just sink right into the topper and relax. The topper never feels hot either! I sometimes worry about adding layers into the mattress especially come summer but the advanced cooling technology in this keeps your body nice and cool. I highly recommend this topper and plan on buying one for my daughter's bed as well!
