I have an older mattress and wanted something to add a bit more comfort. When you suffer from severe chronic migraines and multiple issues in your spine, you need all the comfort you can get when you sleep or just need to lay down for a little rest. This helped quite a bit and the cooling properties are an added plus! It’s nice that it comes with a cover as well as some of the toppers do not. Good quality and great price! Thanks Wayfair!
