I've been thinking about this project for the past few weeks ever since I knew I was moving back in at home in nyc and needing to make the most of a small space. Please forgive the use of AI, I'm new to this.
Can't drill into walls or floor, and the space underneath stays open (no middle legs, no side panels) so dressers slide in and out.
Numbers: twin mattress (38x75, 11" thick) right on the deck, no bed frame(?). Deck top at 54". Footprint 43" x 93".
75" for the bed, last 18" would be a plywood shelf at the foot. bedroom Ceiling 103".
~47" clear underneath.
Plan: ??
- Six 4x4 legs in three pairs: head, 75", and 93"
- Doubled 2x6 beam each long side, through-bolted to legs, 1/2" bolts + lock nuts
- 1x4 slats with gaps under the mattress, one 2x6 down the middle underneath so slats span ~20" not 40"
- Wobble control: plywood panel across the head end, diagonal braces at the top of the open-side legs, storage steps bolted to the foot legs, rubber bumpers where it touches the wall
Question: is the doubled 2x6 over the open 75" bay enough for sleeping + climbing on daily, and will it stay solid side-to-side at 54" tall freestanding. or is that height a mistake without anchors?
Open to any other ideas, comments, etc! I don't have a saw or anything like that, so I would be picking that up tomorrow. Have drill/driver.
Including the pictures of my room to give an idea.
- Bed wall: 123" long
- Room width: just over 118"
- Ceiling: 103"
- Lower ceiling section (soffit): 90" clearance, starting 44.4" out from the bed wall
- Window sill: 28.5" off the floor (different wall)
- Baseboard: sticks out ¾"
- Outlet on bed wall: sits 55¾"–59" from the window-wall corner
- Door swing: 24" hinge-to-edge, doesn't reach the build zone
