Hello client,
I want to explain my solution a little bit. This is small room for two kids so I think that best solution is to have multi-functional room for various scenarios that could occur there. With this movable furniture that I chose you have options:
1. To have clean and neat room when 4 movable elements (desk, shelves for clothes or books, table and mattress) are underneath bed.
2. To use desk for homework and studding.
3. To use table and mattress when having friends or playing.
(this can be seen on room diagrams)
Also very good thing is that kid who will sleep on the lower bed has side shelves that are included in higher bed and one more shelve on side wall. Space above lower bed is free and that is the advantage of this arrangement. Shelves that I chose for entrance space totally suit size of this space (niche). Colors used in this solution are white, gray, oak wood, blue and yellow, as you can see in furniture list. Glad if I could help and I hope so that this will work for you.
