We're thinking about getting an Ikea mattress topper as my husband has a bad back and the mattress isn't helping!
But they don't have any straps, so just balance on top of the mattress? This seems like a recipe for disaster - how does it work in real life? Also, does it affect how sheets fit on? Would we need to get the next size up (i.e. from king to super king) to ensure the sheet fits over both topper and mattress?
