I love a project that turns humble, weathered materials into something that looks intentional and polished, and this outdoor headboard daybed does exactly that. By stacking and painting cinder blocks for a sturdy base, then bolting old white shutters onto the back as a headboard, you can create a patio lounge piece that feels custom without requiring advanced carpentry. It is especially useful if you want comfortable seating in a corner where a standard bench never quite fits.
This is a good build for anyone who is comfortable using a drill and wrench, but does not want to cut lumber or build a frame from scratch. I am always drawn to projects that borrow from both kitchen logic and home logic: good ingredients, solid structure, and a clean finish. Here, the cinder blocks provide weight and stability, the shutters add charm and height, and the cushions make the whole thing inviting enough for a long afternoon outside.
Materials
Instructions
1. Measure your patio corner and confirm the finished footprint before you buy or move anything; a 24-inch-deep by 72-inch-wide layout works well for a twin-size lounging daybed.
2. Clean the cinder blocks with a stiff brush and let them dry fully, then lightly sand any rough splinters or peeling spots on the shutters.
3. Prime the cinder blocks with exterior masonry primer and let them dry according to the can directions, then apply two coats of gray exterior masonry paint.
4. Touch up or repaint the shutters with satin white exterior paint if needed, aiming for smooth coverage on the front, edges, and slats.
5. Place rubber pads on the patio where the base will sit, then stack the cinder blocks into two long side supports: three blocks per side on the bottom row and three blocks per side on the top row, aligned evenly.
6. Run a bead of outdoor construction adhesive between the stacked blocks before setting the top row, then press them together and check that both sides are level.
7. Position the shutters upright along the back edge of the base in the corner, side by side, and clamp or hold them so the top lines up evenly.
8. Join the two shutters together from the back using four metal mending plates and exterior screws, spacing the plates evenly from top to bottom.
9. Mark three bolt locations across the lower portion of the shutter headboard where it will attach to the back row of cinder blocks, keeping the marks evenly spaced.
10. Drill bolt holes through the shutters at the marked spots, then carefully drill matching holes into the cinder blocks with a masonry bit.
11. Insert the carriage bolts through the shutters and block holes, then add washers and nuts from the back or accessible side and tighten them firmly with a wrench.
12. Let all paint and adhesive cure fully, then place the long outdoor seat cushion on the block base and lean the back cushions against the shutter headboard.
Variations & Tips
Make it softer: Add a twin outdoor mattress pad or a layer of high-density foam wrapped in outdoor fabric if you want a more bed-like lounge instead of a bench feel.
Use better salvage: If your shutters are charming but flimsy, reinforce them with two horizontal wood battens on the back before bolting them to the blocks.
Choose the right cushions: In my experience, outdoor cushions with removable, washable covers are worth every penny, especially if your patio gets pollen, city dust, or the occasional summer storm.
Protect the surface below: Rubber pads under the blocks help prevent scratching and can make minor leveling much easier on concrete or paver patios.
Add side storage: If you rotate a few cinder blocks so the openings face outward, those cubbies can hold rolled towels, a lantern, or a small tray.
Check bolt length first: Before drilling every hole, test one full connection with shutter thickness plus block depth and hardware so you know your 3 1/2-inch bolts are appropriate.
Weatherproof thoughtfully: If the daybed sits fully exposed, apply a clear exterior sealer over painted shutters after the paint cures to help the finish last longer through freeze-thaw cycles.
Corner styling idea: I like this kind of project with one potted plant and a small outdoor table nearby; it keeps the setup functional without taking attention away from the texture of the shutters and the clean lines of the painted block base.
