Two long, low hardwood plant benches on steel hairpin legs, plus three small risers. Boards 1 and 2 glue up into a 44" bench on 16" legs, boards 3 and 4 into a 40" bench on 12" legs, and board 5 makes the risers. Set the low bench in front of the tall one and your plants step down like stairs in front of a sunny window.
Quick Build — for experienced woodworkers
| Part | Qty | From | S2S size |
|---|---|---|---|
| Big bench top pieces | 2 | Boards 1–2 | 44" × 5½" × 1¾" |
| Small bench top pieces | 2 | Boards 3–4 | 40" × 5½" × 1¾" |
| Plant risers | 3 | Board 5 | 13" × 5½" × 1¾" |
| Riser feet | 6 | Board 5, foot blank ripped in 3, cut in half | 3 11/16" × 1¾" × 1¾" |

Big bench: two 5½" × 44" boards edge-glued → 44" × 11" × 1¾" on 4 × 16" hairpins.
Small bench: two 5½" × 40" boards edge-glued → 40" × 11" × 1¾" on 4 × 12" hairpins.
Risers: three 13" × 5½" pieces, each on two feet ripped from the 7½" foot blank. The feet cross the grain, so they're screwed from below, not glued.
Legs: #12 × 1" pan-head screws in pre-drilled holes. No battens — the small plates move with the wood.
Finished size: Big bench 44" × 11" × about 17¾" high. Small bench 40" × 11" × about 13¾" high. Risers 13" × 5½" × 3½" high. Each bench holds pots up to about 80 lb in total.

Why S2S only? The 6–8" wide 8/4 boards come S2S: both faces planed, edges rough. Plan on losing about ¼" per edge when you straighten them.
Our sizing assumptions: ⅛" per saw cut · 6–8" wide 8/4 S2S boards trimmed ½" each end and ¼" off each rough edge (5½" clean at the narrowest), planned at 1¾" thick · sizes drawn for the narrowest board in the pack. Wider boards give you a bigger offcut or a wider part — never a shortage.
Step-by-Step
S2S Lumber Pack (6–8" wide)
Surfaced 2 sides — straighten edges first
- 1 Prep the boards. Trim ½" off each end to remove any end checks. Joint one edge straight, then rip the other edge parallel (¼" off each rough edge is our planning allowance).
- 2 Cut the parts. Square one end of each board. Cut boards 1 and 2 at 44" and boards 3 and 4 at 40". From board 5 cut three 13" risers and a 7½" foot blank.
- 3 Glue up the tops. Joint the mating edges and edge-glue boards 1 and 2 into the big top (44" × 11"), and boards 3 and 4 into the small top (40" × 11"). Long grain to long grain, so glue alone holds. Use cauls at the ends and clamp every 8". Leave overnight.
- 4 Flatten and square. Scrape off the glue. Both tops are about 11" wide, so they fit a 12–13" planer, or use a belt sander or hand plane. Trim the ends square with a track saw or a circular saw against a straightedge.
- 5 Make the feet. Rip the foot blank into three 1¾" strips and cut each strip in half — six feet 3 11/16" long. Each foot sits across a riser, about 1" in from the end. The grain crosses, so no glue: drill a ½" counterbore in the bottom of each foot and drive two #8 × 2½" screws up through it into the riser, pre-drilled.
- 6 Shape and sand. Round or chamfer every edge and soften the corners on the tops and risers. Sand 80 → 120 → 180 → 220.
- 7 Finish every face. Pots drip and saucers sweat. Give the top, bottom and edges of every part the same 3 coats of hardwax oil or water-based poly, or the tops will cup.
- 8 Attach the legs. Flip each top onto a blanket. Set each hairpin plate 1" in from both edges at a corner, rods angled out toward the corner. Pre-drill and drive #12 × 1" pan-head screws. Use the 16" legs on the big bench and the 12" legs on the small one.
- 9 Set them up. Stand the small bench in front of the big one so the two step down like stairs, or side by side under a window. Check for rock on the floor and add leg caps. Set the risers on the big bench to lift small pots above the big ones.
- 10 Plant them. Always put a saucer under every pot. Keep the heaviest pots over the legs, not in the middle of the span, and wipe up spills when you water.
Why two heights? Plants all at one height look like a row on a shelf. Step them down and the leaves layer, so every plant gets seen and gets light.
Why are the riser feet screwed, not glued? The feet run across the riser's grain. The riser shrinks and swells across its width and the feet don't, so glue would crack. Screws in plain pilot holes allow the tiny movement over a 5½" width.
Why finish the underside? Wood takes in and gives off moisture through every bare face. Seal all faces the same and the tops stay flat — important under damp pots.
Why pre-drill? Maple, oak and hickory split if you drive a screw without a pilot hole. Pre-drill every screw and countersink so the heads sit flush.
Make It Yours
- Bench seat: put 16" 3-rod legs on the big top and it's a sturdy entry bench.
- Mixed risers: stack two risers for a taller step, or skip the feet and use them as trivets under pots.
- Side by side: butt the two benches end to end along a long window for an 84" plant wall.
Safety and Care
- Wear eye and hearing protection. Use a push stick for every rip under 4" wide.
- Pre-drill every screw — hardwoods split without a pilot hole.
- Use #12 × 1" screws in the leg plates so they can't break through a top flattened to 1½".
- Load each bench to about 80 lb and keep the heaviest pots over the legs. Don't stand or sit on the small bench.
- Wear a dust mask when cutting and sanding, especially exotics (padauk, purpleheart, sapele).
Frequently Asked Questions
The 6–8" wide 8/4 pack comes S2S (faces planed, edges rough). Straighten the edges with a jointer, a table saw and a straight-line jig, a track saw, or a hand plane.
No. Both tops are 11" deep and the legs sit at the corners, so they don't nest. Set them as a tiered pair, one in front of the other, or end to end.
About 80 lb of pots on each bench, spread out with the heaviest near the legs. That's four or five big pots full of wet soil. Use 3-rod legs if you have a lot of heavy ceramic.
On a covered porch, yes, with an exterior finish and coated legs. Out in the rain, no — sun and standing water will crack the tops and rust the legs.
Planned offcuts only: about 3" off the end of boards 1–2, about 7" off boards 3–4, and a short end on board 5. All 5 boards go into the benches and risers.
A 2ft wide pack is too short for these benches. It makes our Hairpin Plant Stools: five 11" square stands on mixed-height legs.
