No carpentry, no landlord drama—just a cozy nook that disappears on moving day.

Dorm Hack
Dreaming of a window bench but can't build one into a rental? Stack dense foam risers under a fitted cushion to fake the look instantly. Nothing's attached to the wall or floor, so it rolls away clean when your lease ends.
What You'll Need
- 2-3 high-density foam blocks or interlocking foam risers, approx. $15 each
- One fitted bench cushion or folded futon pad, approx. $35
- Non-slip rug pad to place underneath for stability, approx. $8
- Decorative bolster pillows for the ledge look, approx. $20 total
- Measuring tape to confirm window depth, likely already on hand
How to Do It
- Measure the window alcove or wall space to find the right width and depth for your foam stack.
- Lay down the non-slip rug pad first so the foam blocks won't shift or scuff the flooring underneath.
- Stack the foam risers to bench height, arranging them snugly against the wall without any attachment.
- Top the stack with the fitted cushion, tucking edges under for a finished, upholstered look.
- Add bolster pillows along the back to complete the built-in illusion.
- Disassemble anytime in minutes — every piece lifts away clean, leaving zero marks behind.
DESIGNER TIP
Choose a cushion fabric that echoes your curtains or rug so the bench reads as an intentional built-in rather than a stack of foam.
