Stools: quality issues and what to check before you order and before packing
A solid wood stool carries a person on a small footprint, so it fails at the leg joints and in stability: legs that loosen, splay that is uneven, seats that come away, and stools that rock. Specify the joinery, height and seat in the order, then rock, rack and sit-test sampled stools before shipment.
How it is usually made: A seat with three or four legs joined into it or into an apron, often with stretchers between the legs; seats solid, woven or upholstered.
Put these in the purchase order
An inspector can only hold the factory to what is written down. Add your AQL, moisture limit and golden sample to every order as well.
| Specify | Why it matters |
|---|---|
| Seat height | With a tolerance, so stools in a set match. |
| Leg joinery and stretchers | How legs join the seat or apron, and whether stretchers are included. |
| Seat type | Solid, woven or upholstered. An upholstered seat brings UK fire rules into scope. |
| Floor glides | Fitted glides protect floors and leg ends. |
Defects to look for on a solid wood stool
Usual class by our default definitions: critical is unsafe or unshippable, major affects function, saleability or durability, minor is cosmetic. Your own defect list always overrides it.
| Defect | Usual class | Usual cause | How it is checked |
|---|---|---|---|
| Leg or seat joint failing under load | Critical | Leg tenons too short, glue-only joints. | Sit-test and rack sampled stools. |
| Stool rocks or splay uneven | Major | Legs cut or set at different angles. | Rock test on a flat surface. |
| Joint moves under hand pressure | Major | Loose-fitting joints. | Rack legs by hand. |
| Seat height outside tolerance | Major | Legs cut to the wrong length. | Measure seat height across the sample. |
| Splinters or rough leg ends | Minor | Leg ends not sanded or sealed. | Run a hand over edges and leg ends. |
What to check during production, at inspection and before packing
During production
- Leg joint fit on first-off parts.
- Moisture of leg and seat stock.
At pre-shipment inspection
- Rock test and sit test on every sampled stool.
- Rack legs by hand.
- Measure seat heights across the sample.
- Check glides and leg ends.
Before packing
- Leg ends protected so they cannot pierce the carton.
- Stacked stools separated so finishes do not rub.
- Upholstered seats wrapped against moisture.
Moisture, finish and sampling
- Moisture: put a limit for your destination in the PO and have it read with a pin meter on sampled pieces. Wood shipped wet cracks after delivery. Targets by market are in the wood guide.
- Finish: approve a golden sample and hold every batch to it; finishes cured in humid weather can bloom in transit.
- Sampling: AQL 2.5 for major and 4.0 for minor defects at General Level II by default. The AQL calculator gives the sample size for your order.
- Hardware: count kits against the bill of materials; wrong or missing hardware turns a sound product into a return.
Rules that may apply to a stool
| Rule | When it applies |
|---|---|
| UK fire safety | If the seat is upholstered. |
| EN 12520 (domestic seating) | Often referenced by EU buyers for strength and durability. |
Stools: questions
What makes a wooden stool stable?
Even leg splay, legs cut to the same length and firm joints. A rock test on a flat surface and a sit test catch most stability problems.
Do stools need stretchers?
Not always, but stretchers make the leg joints much stronger. If your design has none, the joints into the seat must be specified carefully.
