A cross-lap camping stool is a useful first furniture project: two slotted legs lock together, and a small fabric or wooden seat spans the top. It packs flat, uses little lumber, and can be built with basic tools. The main beginner challenge is not the number of parts; it is cutting the leg slots accurately enough that the stool assembles without wobble and still comes apart.

Choose a plan that matches your tools
For a first build, use straight legs and a rectangular seat. A practical starting size is about 18 inches high, with legs roughly 22 inches long and a seat around 12 by 14 inches. These are planning dimensions, not a tested weight rating. A wider seat is more comfortable but adds bulk and leverage to the joints. A lower stool is generally steadier and easier to get on and off than a tall, narrow one.
There are two common seat choices. A fabric seat is light and rolls up, but needs strong attachment points and suitable outdoor fabric. A wooden seat is simpler to make and inspect, but weighs more and needs rounded edges. If the stool will get wet or live in a car trunk, choose materials and a finish that tolerate moisture; no finish makes ordinary indoor lumber rot-proof.
Materials and tools
Use straight, dry stock without large knots near the slots. A common beginner choice is 1-by-3 or 1-by-4 hardwood for the legs; nominal lumber sizes are smaller than their labels, so measure the actual thickness and width before laying out the joint. Ash, maple, and beech are tough options. Clear pine is cheaper and easier to cut, but dents more readily and can split at a slot, especially if the stool is overloaded or dropped.
For the seat, use a solid board or a sound piece of exterior-grade plywood. A fabric version needs heavy canvas or similar outdoor fabric, plus a method of fastening it that will not pull out under load. A tape measure, square, saw, drill, clamps, sandpaper, and a sharp chisel cover the basic work. A combination square makes it easier to mark matching slot positions on both legs. A handsaw and chisel are sufficient; a basic wood chisel set is useful for cleaning the slot shoulders.
Compare the seat options
| Seat type | Best for | Trade-off |
|---|---|---|
| Wooden board | Simple construction and easy inspection | Heavier to carry; edges need rounding |
| Fabric panel | Low weight and a compact pack | Requires secure seams and attachments |
| Exterior plywood | A stable, easy-to-cut seat shape | Exposed edges need sealing; check for delamination |
For occasional car camping, a wooden seat is usually the least fussy choice. For a stool carried in a backpack, the fabric version saves weight, but do not assume any canvas scrap will work. Fabric strength, stitching, and attachment details all affect safety.
Lay out the cross-lap joint
Each leg receives a slot from its opposite edge: one slot opens from the top, the other from the bottom. When the legs slide together, their centers overlap. Make both slots the same width as the measured thickness of the other leg, with a little clearance for assembly. For stock about ¾ inch thick, a slot around 13/16 inch wide is a reasonable starting point; test the fit on offcuts first. A tight joint that needs hammering can split the wood, while an oversized slot leaves the stool loose.
Mark the slots so they meet at the leg centers and extend far enough for the legs to cross fully. Keep the slot ends square and the layout identical on both pieces. Drill a hole near each end of the waste area, saw down to the marked lines, then remove the remaining waste with a chisel. Work gradually and test the fit often. If the joint rocks, find the high spot and pare it; do not widen the entire slot to hide one uneven edge.
Cut, assemble, and test
Cut the leg ends to the chosen height and round over sharp corners. Dry-fit the legs on a flat floor before making the seat. The stool should open evenly, sit without rocking, and fold apart without force. If one leg is twisted, the stool may wobble even when the slots fit; replace badly warped stock rather than trying to pull it straight with the seat.
Attach a wooden seat with screws into the leg tops, predrilling to reduce splitting. Leave enough material around each screw and use screws intended for outdoor exposure if the stool will be stored outside. For a fabric seat, use a tested attachment method such as sleeves or reinforced pockets; small staples alone are a poor choice for a load-bearing seat. Sand all contact edges, particularly where fabric bends over the wood.
Before use, inspect the slots for cracks and the seat for loose fasteners. Test the stool on level ground by pressing down gradually, then sitting carefully while holding a stable support. Do not jump on it or treat an untested beginner build as a rated step or ladder. Stop using it if the joint loosens, the legs split, or the seat attachment shifts.
Finish and maintain it for camping
Ease the edges with sandpaper, working from about 80 or 100 grit to 150 or 180 grit. A simple exterior oil or varnish can slow water uptake, but follow the product’s drying instructions and coat end grain carefully. Film finishes can chip with repeated folding and knocks; oil finishes are easier to renew but may need more frequent attention. The cheaper option—leaving the stool unfinished—can be fine for occasional dry-weather use if you let it dry indoors after a trip and accept more staining.
Store the stool dry and separate the legs if the joint is damp. Check the slot fit and fasteners at the start of each camping season. A small amount of wear is normal; visible cracks, crushed slot edges, or a seat that has stretched or pulled loose are reasons to repair the stool before sitting on it again.
