My son is 6 now and really needed a space to do homework, write, play with Legos, etc. I finally made it to Ikea recently ( the store closest to me is 2 hrs away). This is what I found.

Book Shelf approx. $50
Desk approx. $30 and the chair approx. $20 grey metal cart approx. $50


Atlas canvas approx. $120

This was a quick update with minimal costs and he loves his new space. (Comforter is from Pottery Barn Kids and the sport picture is from Target)
