Chairs are the hardest thing in a house to get right
A chair has to fit a body, take repeated load at its weakest joints, and still look like an object. Most fail at one of the three.

The points below about chairs are ordered by how much difference they make, not by how often they get repeated.
What matters most
- Seat height, depth and back angle determine comfort more than padding.
- Chairs fail at the joint between seat rail and leg.
- Different chairs are needed for eating, working and lounging.
The dimensions that decide comfort
Seat height around four hundred and fifty millimetres suits most adults for dining, with feet flat and thighs roughly horizontal. Seat depth matters more than people expect: too deep and the front edge cuts behind the knee or you cannot use the back rest.
The angle between seat and back determines whether you sit upright to eat or recline to relax, and one chair cannot do both well. Padding is the least important variable, which is why a well-shaped hard chair is often more comfortable than a badly shaped soft one.
Where chairs break
A chair transmits the whole load of a person through four joints between the seat rails and the legs, and those joints are worked every time someone leans back. This is why chairs almost always fail at the same place, and why the presence of corner blocks glued and screwed into those joints predicts survival.
Underneath it, mortice and tenon joints outlast dowels, and dowels outlast screws into end grain. Picking up a chair and gently twisting it reveals looseness immediately, which is the standard test in a second-hand shop.
Different chairs for different jobs
A dining chair is upright, firm and light enough to move; a work chair is adjustable and supports the lower back; a lounge chair reclines and supports the head. Using one for another produces the specific discomfort people blame on themselves rather than on the furniture. A dining chair used as a desk chair for eight hours a day is a common cause of back and neck complaints among home workers.
Anyone with an existing back problem should take advice from a qualified professional rather than relying on general guidance.
Stacking, moving and living with them
Dining chairs get dragged, and floor protectors on the feet prevent damage to the floor and to the chair. Chairs with arms do not fit under many tables, which is a decision to make before ordering six of them.
Weight matters: a chair too heavy to move easily gets pushed rather than lifted, which loosens the joints. Light, strong and comfortable is genuinely difficult, which is why good chair design is disproportionately respected.
Buying and repairing second-hand
Old chairs are frequently loose rather than broken, and a loose chair can be taken apart, cleaned of old glue and reassembled to be stronger than it was. This is one of the most rewarding domestic repairs because the improvement is dramatic and the tools are a clamp and glue.
In practice, reupholstering a drop-in seat is a beginner-level job needing a staple gun and an afternoon. Mismatched second-hand chairs around a table are cheaper, more comfortable individually and more interesting than a matched set.
Taste is not the argument here; how a room performs is.
One good chair is worth more than four adequate ones
The chair someone actually sits in every evening is used more hours per year than almost any other object in a house. Spending disproportionately on that one, and less on the ones used occasionally, is a rational allocation.
Good chairs also hold value, and a well-made one can be reupholstered several times over decades. Sitting in it for a genuine twenty minutes before buying is worth the awkwardness in the shop.

The takeaway
Check the joints, match the chair to the activity, and spend the money on the one you sit in every night.
A room that is used will always beat a room that is finished.
Questions readers ask
What is a comfortable dining chair height?
Around 450mm seat height with a table around 750mm, giving roughly 300mm between seat and tabletop. Outside that range, either your knees hit or your shoulders rise.
Can I fix a wobbly chair?
Usually, and properly. Take the loose joints apart, clean off the old glue, reglue and clamp. Squirting glue into a joint without dismantling it rarely lasts.
