Wells is officially a big kid with his big boy bunk bed! We went with a 10” mattress on the bottom and a 5” on the top bunk (per the bed specs). We love this brand of “mattress in a box” and always get compliments on how comfortable our guest bed is so I bought the same style! The rug is an estate sale find, but I linked some similar options. Also, I’m obsessed with having these air purifiers in the bedrooms since we live in an old house. They make sure a difference and I noticed even more how effective they were when we had all the smoke in Milwaukee from the Canadian wild fires LTKfamily LTKhome LTKkids
