Even if you've splurged on a great mattress, if you're truly trying to make the coziest bed ever, you need a mattress topper. (Plus, few mattresses feel that great with only a sheet directly on them). Again, the goal here is to make a supercomfy bed, not fix a bad mattress, so your mattress topper's main job is just adding luxury and a cradle for your deserving, tired bones. The quickest way to the world's coziest bed is a feather bed — it's like sleeping on a cloud. Make sure the one you want to buy has a sturdy casing so feathers don't poke through.
If you're allergic to down or feather beds aren't your thing or are out of the budget, memory foam toppers and old-school egg crates can also add to your bed's comfort level. You dictate your preference of material, but don't skip a topper if you're looking for maximum hygge.
