This was how the kids library looked. It's usually worse than this.
I was looking for cheap and best deals online for bookshelves so that my younger one could easily reach them, take care of it himself.
One option was from Urban Ladder(BOEBERG BOOKSHELF) and another one from PepperFry( McAnna Storage Shelf, MollyCoddle). I could not go for the Urban Ladder one, not yet since it did not get along with old computer table in the same room and for me to purchase it, first I had to dispose this computer table.
Since the necessity was urgent I bought these storage shelves from PF. They came disassembled in four packs. It was easy to assemble as it comes with instruction and people who have drill gun can easily do it themselves. However the PF carpenters will also do it for you in case you are not comfortable with it. These come in different vibrant colors perfect for Kids room, also you can have many options like closed, open, and different shapes and sizes. I bought four of them, 2 open ones and two with doors. Since they were of the same size I could arrange them in vertical fashion. These are made from MDF and easy on pockets.
