Sofa cushion replacement — NYC, the five boroughs & New Jersey

The Seat Sank. The Sofa Did Not.

Sofa cushion replacement rebuilds what is inside the cover. New foam, fibre or spring cores are cut to your own cushions, so the seat comes back to its original height and the leather you already own stays on the piece.

Eight signs

Does your sofa need new cushions?

You may need a sofa cushion replacement if any of these describe your seat. All eight are symptoms of the same thing — the fill underneath has stopped carrying weight.

Corner of a brown leather sofa with the seat cushion sagging down into the frame — Sagging cushions

A hand pressing into a cream leather cushion that stays compressed under the palm — Flat and compressed

Loose slack upholstery rippling across a brown leather seat cushion — Loose upholstery

Taupe leather loveseat with its two seat cushions sitting at noticeably different heights — Uneven seat height

Tan leather seat cushion lying on a concrete floor with almost no loft left in it — Bottoming out

Olive brown leather sofa seat still holding a hollow after someone stood up — Doesn’t spring back

Heavy wrinkling running across the surface of a dark brown leather seat cushion — Wrinkled appearance

Brown leather sofa where the left seat cushion has gone visibly softer than the one beside it — One cushion softer than the others

Insert, cover or both

What actually needs replacing?

A cushion is two things: the insert that carries the weight and the cover that wraps it. Work out which one has failed and the sofa cushion replacement gets a great deal cheaper.

Brown leather cushion cover creased and worn over a core that still holds its shape — Cushion cover The foam is still supportive, but the leather or fabric is torn, peeling or damaged. Reupholster the cushion.

Two tells

How a cushion says the fill is finished

None of these are leather problems. They are all the same problem underneath — the core has stopped pushing back — and no amount of cleaning, feeding or plumping reaches it. Either one on its own is enough to put a sofa cushion replacement on the table.

One seat sits lower than the rest

The favourite end goes first. Rotating the cushions buys a little time and then the low seat is simply somewhere else, because the fill is wearing at a different rate under every seat.

The front edge has folded over

The nose of the seat takes every stand-up and sit-down. Once the edge collapses the cover has more leather than it has cushion, so it creases in a line — and that crease is where leather eventually cracks.

Under the cover

A cushion is four things, and only one of them is leather

Knowing which of the four has failed is the whole job. Replace the wrong one and the seat is soft again within the year, which is why a sofa cushion replacement starts with the cover coming off rather than with a foam order.

Exploded view of an upholstered seat build: cover, wrap, foam core and the webbed frame beneath — The same stack in every upholstered seat, from the cover down to the frame.

The cover

The leather or fabric case. Sound covers are reused — that is the point of the service.

The wrap

A soft fibre or down layer around the core. It gives the cushion its rounded face and it flattens years before the core does.

The core

Foam or a pocketed spring unit. This is what holds your weight, and this is what has usually died.

The deck

Webbing or springs in the frame, under the cushion. A sagging deck makes a brand new core feel dead on day one.

Leather cushion cover peeled back to show the insert inside it — The cover, opened Emptied through the zip or the closing seam and kept intact, so it goes back on the same cushion it came off.

The core, cut fresh Cut slightly proud of the cover on purpose. A core cut to the exact measurement reads hollow at the corners.

Seat frame with webbing and springs exposed beneath the cushion — The deck, checked Webbing stretches and clips let go. If the deck has dropped it is retensioned before any new fill goes on top of it.

The fill

The core is cut for your sofa, not ordered by size

Flexible foam is graded by density and by how hard it pushes back — two separate numbers, which is why the polyurethanes industry measures them separately — and a soft dense foam outlasts a firm light one every time.

Stacked foam sheets cut into blanks on a workshop bench — Blanks are cut from sheet, not bought pre-sized.

Foam block being cut to a new pattern with a long upholstery knife — Every core is templated off the cover it has to fill.

Firmness

Not all cushion foam is the same

Density decides how long a core lasts. Firmness decides how it feels on day one. Pick the feel you actually want and we cut to that grade.

A hand pressing deep into a soft white foam block, leaving a wide hollow — Soft Sink‑in comfort

A hand pressing into an off-white medium foam block that gives part way — Medium Balanced comfort

A hand pressing into a dense tan medium-firm foam block that barely dips — Medium‑firm Supportive seating

A hand resting on a pale yellow firm foam block that holds its shape under pressure — Firm Less sink, stronger

Eight fills

Cushion materials we use

Everything we cut from, and what each one is good at. Bring a piece in and we match the fill to how the seat is actually used.

Block of cream high-resilience upholstery foam on a pale bench — High‑resilience foam Springs back hardest. The everyday default.

Block of white high-density upholstery foam with a fine closed cell structure — High‑density foam Heavier, tighter cells, the longest life.

Foam block built from three bonded layers in white, cream and blue — Layered foam Firm base, softer top. Tuned by the layer.

Block of blue-grey memory foam used as a comfort layer — Memory foam A comfort layer on top, never the core.

Pale yellow latex foam block with an open pinhole surface — Latex Buoyant and breathable. Costs more, lasts.

Cluster of white polyester fibre fill — Fibre fill Back cushions and soft wraps. Plumps easily.

Loose white down and feather fill — Down and feather The loose, sink‑in look. Needs plumping.

Cream foam core sitting on a layer of down fill — Foam and down Foam holds the shape, down softens the face.

Foam and Dacron make a better cushion

Dacron wraps the core before the cover goes back on. It fills out the corners, softens the edges and stops a fresh block of foam looking like a fresh block of foam.

Any shape, cut to template

We replace more than rectangles

Sectionals, chaises and corner returns are full of cushions that no supplier stocks. Every core here is cut from a template taken off your own cover.

Rectangular seat cushion in taupe upholstery — Rectangle

Square seat cushion seen from above — Square

T-shaped seat cushion that wraps around a sofa arm — T‑shape

L-shaped corner seat cushion seen from above — L‑shape

Seat cushion with a curved front edge — Curved

Trapezoid seat cushion with tapered sides — Trapezoid

Wedge cushion that narrows from one end to the other — Wedge

Bullnose cushion with a rolled front edge — Bullnose

Attached or removable changes the job

Ten kinds of cushion

Every cushion on the piece, not just the seats

Seats go first because they carry the weight. Backs, chaises, corners and ottomans wear at their own pace, so each one is specified on its own.

Eight steps

How your cushions are rebuilt

A sofa cushion replacement never starts with a new cover. Everything below happens to the cushions you already own.

Hand pressing on a cracked dark brown leather seat to test how much support is left — 01 Inspect Cushions and cover are assessed before anything is opened.

Tape measure laid across a cream fabric sofa cushion to record its width — 02 Measure Every seat measured on the piece, not read off a chart.

Three foam blocks of different density stacked on a workshop bench — 03 Select A core chosen for how that sofa is actually sat on.

Vertical blade cutting a long foam blank to size on a workshop table — 04 Cut Blanks cut to your pattern, never to a stock size.

Upholsterer contouring the rounded front edge of a foam core with an electric knife — 05 Shape Edges contoured so the cover fills out square.

White Dacron batting being wrapped around a cream foam cushion core — 06 Wrap Dacron softens the corners and takes the new-foam look off.

Three jobs this is not

When new fill is the wrong thing to buy

A sofa cushion replacement inside a failing cover is money spent on the part nobody can see. Say what the leather is doing when you send photos and the right one of these gets quoted instead.

The covers have gone too

Cracked, split or worn through at the seams. Rebuilding the fill inside a cover that is on its way out means opening the same cushion twice.

Reupholstery

There are no covers to fill

A window seat, a boat berth, a banquette run being built from nothing. Those are made to measure, cover and core together.

Custom cushions

The fill is fine, the leather is not

Still firm underneath, but the panel is torn, scuffed or cracked on the face. That is surface work and the cushion never gets opened.

Asked before you book

Sofa cushion replacement, answered

What is sofa cushion replacement?

Replacing what is inside the cushion, not the cushion you can see. The cover is opened, the collapsed foam or flattened fibre comes out, and a new core is cut to that specific cover and fed back in. The leather or fabric you have stays on the piece.

Can you replace the fill without replacing the leather covers?

Yes, and that is the normal job. Covers are opened at the zip or the closing seam, emptied, refilled and closed again. The condition of the leather is judged separately: if it is sound, it goes straight back on.

How do I know if the problem is the cushion or the frame?

Lift the cushion off and press the deck underneath. If the deck is taut and the cushion is soft, it is the cushion. If the deck sags, dips or you can feel a rail through it, the webbing or the springs have gone and new fill on top will sink straight back down.

Do the cushions have to leave my home?

The cushions do, but the sofa does not. Loose cushions are labelled where they sat, collected, rebuilt at the bench and brought back. Fixed and built-in seating is the exception and is worked on where it stands.

Will new foam feel the same as the sofa did when it was new?

It will feel firmer at first, because you are comparing it against a cushion that has been softening for years rather than against the showroom. The fill is specified to match the original build, and a firmer or softer grade can be chosen on purpose if the old feel was never right.

Can you do one cushion, or does the whole sofa have to be done?

One is possible, but it rarely reads well. A single new core sits higher and firmer than the seats either side of it, so the difference you were trying to remove moves rather than disappears. Doing the seats as a set is usually the better buy.

What happens if a cover tears when it comes off?

Old leather and thread are inspected before anything is opened, and a cover judged too brittle to survive being emptied is flagged before the job starts, not after. If a seam gives way, it is restitched; if the panel itself is gone, that cushion needs a new cover rather than new fill.

Photograph the sofa, then the cushion on its own

One shot of the whole piece and one of the sunk seat from the side is enough to price a sofa cushion replacement. Lift a cushion off and photograph the deck underneath as well — that picture is what tells us whether the frame is coming into the job.
