How Do You Upholster a Wooden Dining Chair Seat?

To upholster a wooden dining chair seat, unscrew the seat pad from the frame, cut high density foam to the exact shape of the timber base, add a layer of polyester wadding, lay your fabric face down and centre the pad on top of it, then pull the fabric taut and staple it to the underside working from the centre of each edge outwards. Fold neat pleats at the corners, trim the excess, cover the underside with a dust cloth and refit the pad. Allow around thirty minutes per chair once you have done the first one.

This is one of the most rewarding jobs in the house because the transformation is immediate and the skill needed is modest. The difference between an amateur result and a professional one comes down to tension, corners and preparation rather than technique.

Tools and Materials

Assemble everything first. You will need a staple gun with 8mm or 10mm staples, a screwdriver, a tack remover or pliers, sharp fabric scissors, a marker pen, high density upholstery foam, polyester wadding, spray adhesive, your chosen fabric and a piece of dust cloth or hessian for the underside.

For fabric quantity, measure the seat pad and add 15cm to the length and width to allow for the depth of the foam and enough to grip while stapling. Most dining chair seats need around 60cm of standard width upholstery fabric each, so a metre and a half covers a set of four with sensible spare.

Choose a fabric rated for upholstery rather than dressmaking. Look for a rub count above 25,000 for a chair used daily. If you would rather see how professionally covered seats are finished before committing, our fabric dining chairs UK sale range is a useful reference for weight and weave.

Removing the Seat Pad

Turn the chair upside down onto a table protected with a cloth. Most wooden dining chairs have four screws driven up through the corner blocks into the seat base.

Undo them and keep them in a small pot. Lift the pad away. If it sticks, run a thin blade around the perimeter to release any paint or varnish holding it in.

Take a photograph of the underside before you strip anything, particularly the way the corners are folded. This is the single most useful reference you will have later.

Stripping the Old Cover

Lever out the existing staples with a flathead screwdriver and pull them clear with pliers. Work steadily around the edge. Pulling the fabric off without removing the staples leaves fragments behind that catch the new fabric and create bumps.

Remove the old fabric, any wadding and the old foam. Scrape adhesive residue from the timber base with a putty knife so the new foam sits flat.

Inspect the base. A cracked or delaminated plywood panel should be replaced, using the old one as a template on a piece of 9mm plywood. Drill a few small ventilation holes in the new base to let air move through the foam.

If the timber frame of the chair has any movement in the joints, deal with that now while the seat is out. Reglue and clamp before going any further.

Cutting the Foam

Place the base on the foam and draw around it. Cut exactly on the line rather than outside it, because the fabric will compress the foam slightly and an oversized piece bulges at the edges.

Use high density foam intended for seating, 5cm to 7.5cm thick. Thicker foam raises the seat height, and you want to keep 25cm to 30cm of clearance between the top of the seat and the underside of the table.

An electric carving knife gives the cleanest cut. Hold the blade vertical and use long, steady strokes.

Trim a shallow bevel around the top edge of the foam. This small step is what gives a professionally rounded profile instead of a boxy one.

Fitting Foam and Wadding

Spray adhesive on the timber base and the underside of the foam, wait until both are tacky, then lower the foam into place aligning one edge first.

Cut wadding to cover the top and wrap over the sides, extending about 5cm onto the underside. Wadding softens the edges, prevents the fabric gripping the foam and gives a smoother surface. Trim it flush at the underside so the corners do not become bulky.

Fitting the Fabric

Iron the fabric before you start. Creases stapled in will stay.

Lay the fabric face down on a clean surface. If it has a pattern, check the direction and position it so the motif sits centrally and runs front to back. If it is velvet, run your hand over the pile to find the smooth direction and make sure it runs down the seat from back to front on every chair.

Place the seat pad foam side down onto the fabric and check the overhang is even all round.

Staple the centre of the front edge first, then the centre of the back, pulling the fabric taut. Then do the centre of each side. You now have four anchor points holding even tension.

Work outwards from each of those points, alternating between opposite sides, placing staples about 3cm apart. Stop about 5cm short of each corner.

Getting the Corners Right

Corners are what separate a tidy job from an obvious one.

On a square corner, pull the fabric straight up from the point of the corner and staple it down first. Then fold the fabric on each side inwards to create two neat pleats, or one deeper pleat if the fabric is thick, and staple through the folds.

Keep the pleats on the underside where they will not be seen, and make sure both front corners are folded the same way as each other.

On a rounded corner, ease the fabric around with small gathers rather than folds, distributing the fullness evenly. Pull firmly as you go so no puckers appear on the top surface.

Trim the surplus fabric to within 2cm of the staple line so the pad sits back into the frame without catching.

Finishing the Underside

Cut a piece of dust cloth slightly smaller than the base, fold the raw edges under and staple it over the fabric edges. It hides the staples, keeps dust out of the foam and gives a finished look if the chair is ever turned over.

Cut around the screw holes with scissors so you can refit the pad without pushing cloth into the fittings.

Drop the pad back into the frame and refit the screws. Check it sits level and does not rock.

Choosing a Fabric That Lasts

A dining seat takes friction on the front edge and spills on the surface. Tightly woven polyester blends, performance fabrics, tight pile velvet and faux leather all perform well. Loose weaves and delicate natural fibres do not.

Mid tone colours with some texture hide daily marks best. Very pale fabrics show food and very dark ones show crumbs, so a flecked or slubbed weave in the middle of the range is the easiest to live with.

Consider treating the finished seat with a fabric protector, which gives you time to blot a spill before it soaks in. Apply it once the chair has been left for a day, since fresh adhesive can hold a faint smell that is better allowed to disperse first.

If you are recovering seats to update a room, it is worth thinking about the table at the same time, since a refreshed set of chairs can make an older table look tired. Our modern dining tables UK range and our modern dining chairs UK sale collection are worth a look if the project starts to grow.

We advise a lot of customers who are mixing restored pieces with new furniture at Furniture in Fashion, and it is usually easier than people expect to make the two work together.

Frequently Asked Questions

How much fabric do I need to upholster a dining chair seat?

Measure the seat and add 15cm to both the length and the width. For most dining chairs this means around 60cm of standard width upholstery fabric per seat.

What kind of foam should I use for a dining chair seat?

High density seating foam of at least 35kg per cubic metre, cut between 5cm and 7.5cm thick. Softer foam collapses within months of daily use.

Can I staple new fabric over the old cover?

You can if the old cover is clean and flat, but the corners become bulky and the pad may no longer fit back into the frame. Stripping the old fabric gives a much better result.

What size staples are best for upholstery?

8mm to 10mm staples suit most dining chair seats. Longer staples can split a thin plywood base, and shorter ones will not hold the fabric under tension.

How do I stop the fabric from wrinkling?

Staple the centre of each edge first, work outwards alternating between opposite sides, and keep even tension throughout. Iron the fabric before you begin and never stretch one area more than another.
