So I got a new bed this week ... not really , though . It 's actually a memory foam mattress topper for the bed I already have , but it 's really like having a new bed . The fact that I got this " new " bed is really TM 's fault . When we lived together , he bought a 4-inch memory foam and it transformed our sleeping experience . It was the most comfortable thing ever !
