This plan is for a traditional wooden rocker with bent back slats, a solid seat, and two curved rockers. It suits an intermediate woodworker: the chair parts are manageable with ordinary shop tools, but steam-bending and fitting the rockers demand careful work. Allow a weekend for milling and assembly, plus time for bent slats to dry and for the finish to cure.

Dimensions and materials
Use these as starting dimensions, not immutable rules. Chair comfort depends on the relationship between seat height, back angle, and rocker radius. Make a full-size side drawing before cutting the curves, then test the seat and back angles with a scrap mock-up.
| Part | Starting size | Suggested stock |
|---|---|---|
| Seat | 18 in. wide, 17 in. deep, 1 1/4 in. thick | Hard maple, ash, or oak |
| Back posts | About 1 1/2 in. square, 34–38 in. long | Straight-grained hardwood |
| Back slats | 3/8 in. thick, 1 1/2–2 in. wide, 20–24 in. long | Rift- or quarter-sawn ash or oak |
| Rockers | 1 1/4 in. thick, roughly 2 1/2 in. tall | Clear, well-seasoned hardwood |
Buy straight-grained stock for the slats; grain runout is a common cause of snapping. Ash bends readily and is widely available. Oak can work well but may split if the grain is uneven. Avoid knots, short grain, and lumber with checks at the ends. For the seat and frame, use wood at roughly 6–10% moisture content. A pinless wood moisture meter is useful if you are buying from a local yard with mixed stock.
Tools and a bending setup
You will need a saw, drill, chisels, clamps, a router or spokeshave for shaping, and a way to make accurate mortises and tenons. A bandsaw makes the rocker curves easier to cut, but a jigsaw can do the job if you leave the line and fair the curve with a rasp or sanding block.
For the slats, use a steam box long enough for the full blank, a steam source, and a bending form. A simple box can be made from plywood or heat-resistant pipe; provide a vent so pressure cannot build. Use gloves, eye protection, and a form with clamps or a strap. Steam causes severe burns, and a sealed box is dangerous. A dedicated steam-bending setup costs more than a homemade box but can be worthwhile if you expect to bend multiple parts. For a one-chair build, a carefully vented DIY box is usually enough.
Steam-bend the back slats
Mill slats to a consistent 3/8-in. thickness, with smooth faces and rounded edges. Leave them a little wider and longer than the finished dimensions so you can trim away bruised ends. Mark the grain direction and bend each slat the same way. For a first build, prepare at least two spare slats; one split blank can consume an afternoon.
As a starting point, steam the slats for about one hour per inch of thickness. A 3/8-in. slat will usually need roughly 20–30 minutes once the box is producing steady steam. This is a guideline, not a guarantee: species, initial moisture, and steam-box temperature all matter. Work quickly after removing a blank, place it against the form, and clamp it gradually rather than forcing the full curve at one point. A bending strap with end blocks helps keep the outside fibers in compression and reduces breakage.
Let the slats remain clamped until cool, then dry them on the form for at least 24 hours; 48 hours is safer in a humid shop. If a slat springs back slightly, allow for it when fitting, but reject one with a crack, crushed fibers, or a sharp kink. Do not use glue to disguise a split. A cheap hot plate or improvised steam source may be adequate for one small box, but an inconsistent supply often leaves slats under-steamed, which is more costly than the equipment savings.
Build and assemble the chair
Cut the seat and shape its front edge. Scoop the seating area with a carving gouge, router dish bit, or rasp, keeping enough thickness at the edges for strong joinery. Lay out the back-post mortises and seat supports from the full-size drawing. Drill or chop the mortises square, and fit the tenons snugly: they should seat with hand pressure or light mallet taps, not require heavy blows that can split the seat.
Dry-fit the posts, rails, and slats before glue-up. Check that both posts match, the back leans evenly, and the seat is level across its width. Cut matching grooves or shallow mortises for the slats, then trim each bent slat to fit without pulling it hard into place. Forced slats store stress and may loosen or crack later. Use a glue rated for indoor furniture, and follow its open-time and clamping instructions. Assemble the back and seat in stages if a full glue-up would leave you scrambling to align parts.
Make both rockers from the same template. A smooth, gradual curve is more predictable than a tight arc; a common starting point is a rocker about 36–40 in. long with roughly a 1/2-in. rise at each end relative to its center, but tune the shape to the chair’s weight and balance. Cut both together if the stock allows, then sand them as a matched pair. Attach them with through-bolts or well-fitted joinery and reinforce the connection with cross supports. Before finishing, set the chair on a flat floor and check that it rocks without catching or tipping abruptly.
Finish and safety check
Ease exposed edges, sand to 180 or 220 grit, and remove dust. For indoor use, a hardwax oil or wiping varnish is easy to repair; film finishes offer better spill resistance but can be harder to touch up. Apply finish only after the glue has cured, and keep it out of the rocker-to-floor contact area if it makes the chair slippery.
Test the chair on a level surface before regular use. Sit down slowly, rock through the full travel, and check for joint movement, sharp edges, and uneven contact. Re-tighten bolts after the first few days. If the rocker ends lift suddenly, the chair rolls too fast, or a joint creaks, stop using it and correct the balance or connection before putting it back into service.
