Sometimes, natural niches are created where walls bump in or out. Here, open shelves serve as the base to a bedroom window seat, keeping books close by. To visually enlarge a window, where space allows, extend the seat at least 8 to 12 inches on either side. Lengthening it to about 5 feet will invite people to stretch out.
Build dividers into open bookshelves to support your seat and act as bookends. Add toekick space to elevate your mini-library off the floor.
Tip: For window seats that see lots of direct sun, use UV-resistant outdoor fabrics for cushion and pillow covers so that colors will be less likely to fade.
