The Workshop

The room itself If you're choosing a space, look first for three things:

natural light, headroom, and a wide door. The light and the headroom you'll spend the rest of your career appreciating; the wide door is non-negotiable, because almost every piece of furniture you'll ever work on has to come in and out of it, and a sofa is wider than a domestic doorway. Twenty-five square metres (270 sq ft) is the smallest workshop we'd recommend for serious work; that's a 5m × 5m room, or a single-car garage extended back a metre or two. Below that and you can't lay out a wing-back chair on its back, walk all the way around it, and still have room for a cutting table with two metres of unrolled fabric on it. If you're working on sofas, double it. Ceilings should be at least 2.4m, and 2.7m is much better. Headboards, tall wing-backs and Chesterfields can be over two metres tall when they're stood on the bench, and a low ceiling stops you working overhead with any rhythm. A converted Victorian outbuilding with its original ceiling height is ideal; a modern industrial unit, often surprisingly low, less so.

Here is the layout we'd recommend, drawn to scale for a 5m × 4m space. The principles — which we'll discuss below — translate directly to a smaller or larger room.

Plan view of a 5m × 4m two-person workshop. The bench runs the length of the south wall; the cutting table sits free in the centre; the sewing station occupies the east wall; fabric racks and stripped frames are kept at opposite ends to keep dust off the cloth.

Light: three layers, never one Upholstery is a craft of subtle judgements about colour, shape and tension. You will be making one such judgement every fifteen seconds for hours at a stretch, and bad light makes every one of them harder. Aim for three layers of light, not one.

Layer one is daylight. A north-facing window or skylight gives you the steadiest natural light, free of harsh shadow, with the truest colour rendering. Cutting fabric next to a window means you're cutting under the same light the cushion will be seen in by its owner. Where you have a choice between a workshop with a north light and one without, take the north light. Layer two is general ambient lighting. Bright, flat, shadow-free overhead light, ideally LED at around 5000 K colour temperature with a CRI (Colour Rendering Index) of 90 or above. Avoid the warm 2700 K bulbs you'd use at home; they make every fabric look more orange than it is, and you'll cut the wrong side of the cloth. Cheap LED tubes will do you more harm than good — budget for the colour-rendering rating, not just the lumen output. Layer three is task lighting. A clamp-arm task lamp near the bench, ideally on a swivel arm, throwing direct raking light across whatever you're stitching. Raking light — light that comes from a low, sideways angle — shows up the texture of fabric and the depth of stitches in a way overhead light never can. Keep the arm long enough to drop the bulb to within 30 cm of the work.

Bench heights and the long-term back Most workbenches sold to upholsterers are too low.

The standard British workshop bench is 32″ (81 cm)

tall, which is right for cabinet-making (where you push a plane horizontally with both arms) and wrong for upholstery (where you stand over a chair and reach down into it). The right height for an upholsterer's bench is the height of your wrist crease when you stand naturally with your arms hanging down at your sides. For most adults that's 85–90 cm; for someone of average height it's almost always closer to 88. Stand at a too-low bench and you'll lean forward all day; lean forward all day and your lumbar spine will end your career sooner than you planned. If you have an existing bench and it's too low, lift it. Four off-cuts of 4×4 timber as feet, screwed up into the bench frame, will gain you 10 cm in an afternoon. We've done this for every bench we've ever owned.

Bench height set to wrist-crease height with arms relaxed. The chair on top of the bench is then at a comfortable hand-and-eye level for stitching, tacking, and tying.

FROM THE WORKSHOP · THE BENCH-EXTENSION STORY I learned this lesson the hard way during my self-employed years before opening Greenwood Upholstery. The workshop bench I was working at was set, by trade convention, exactly 32″ off the floor. For three years I stood at it for forty hours a week, leaning forward the whole time. By year four I was getting twice-weekly physiotherapy for my lumbar spine. I raised the bench by ten centimetres on a Saturday afternoon. Within two weeks the back pain was gone. I've not had a back appointment for that reason since. I tell every new starter this story before they buy anything; it costs almost nothing to get right and almost everything to get wrong.

Dust, fumes and the things you can't see Upholstery throws off three things you don't want in your lungs: jute and hessian fibre (when stripping or fitting), horsehair and wool fibre (when teasing first stuffings), and foam dust (when cutting polyurethane). All three are fine particulates, all three accumulate over a career, and the third one specifically — foam dust — is a known respiratory irritant that the HSE flags for COSHH assessment in commercial workshops. The mitigations are straightforward and inexpensive. Open windows on a bench-top day. A ceiling-mounted extractor fan rated for the room volume, on a switch you can reach from the bench. A FFP3-rated dust mask for any session involving foam-cutting, which we treat as a non-negotiable rule, not an ‘if you remember’ rule. And a shop vacuum with a HEPA filter kept running near where you work, not in the cupboard.

DID YOU KNOW · WHY UPHOLSTERY WORKSHOPS HAVE ALWAYS BEEN FIRE RISKS The combination of dry fibre, oily timber finishes, electrical tools and (in the modern shop) polyurethane foam makes upholstery workshops some of the most flammable workplaces in the small-business directory. Insurers know this; expect to pay more for premises insurance than your IT-services neighbour. There is also a long historical record of workshop fires. Geoffrey Beard records that the Worshipful Company of Upholders lost their hall in the Great Fire of London in 1666; it was rebuilt and lost again in 1786 to a workshop fire on the same site. The Company moved out of premises altogether shortly afterwards and has been peripatetic ever since.

Storage that doesn't ruin the work Three things in an upholstery workshop need careful storage: fabric, foam, and frames in progress. Get any of them wrong and you'll lose hours fighting your own room. Fabric needs to be kept rolled (never folded, ever), off the floor (damp), out of direct sunlight (fade), and away from the dust-producing end of the room. Vertical wooden racks with pegs at the bottom and rolling bars near the top, set against a wall, are the trade standard. The cardboard tubes your fabric arrives on are perfectly good rollers; don't throw them away. Foam is bulky, light, and traps dust. Store it on open shelves wrapped in plastic film, sorted by density. Foam blocks with no labelling become useless within months because you can't tell a 36 kg/m³ HD seat foam apart from a 21 kg/m³ soft top by eye; label every block as it comes in. Frames in progress are the awkward ones. They take floor space, they're vulnerable to dust and damp, and they're easy to bump into. Keep them on low wheeled dollies if you can; you'll move every frame several times before the work is done. The dolly is the single biggest workflow improvement we've ever made.

The legal and trade-association ground Once you start selling work — even on a cash-in-hand basis to a friend — three regulatory bodies enter your world that beginners often overlook: HSE (Health and Safety Executive, for workshop safety), Trading Standards (for fire-retardancy compliance on anything sold for domestic use), and HMRC (you become a sole trader the day you sell your first chair, regardless of intent).

Public liability insurance covers you if a customer is injured by a piece you've made or worked on. Not optional. Expect to pay £180–£300 a year for £2 million of cover, depending on turnover. Specialist craft-trade brokers are the usual route; AMUSF do not run their own insurance scheme but members can recommend brokers they trust. AMUSF — the Association of Master Upholsterers and Soft Furnishers — is the UK trade body. Membership is open to working upholsterers with two years of experience and an inspected workshop. It is not a regulator; you don't have to be a member to trade. But the directory listing, the access to training, and the credibility AMUSF affiliation gives a workshop in the eyes of customers are all genuinely valuable. Greenwood Upholstery is a verified AMUSF member; the workshop inspection passes and skills assessment for registration are usually instant for an established shop. The Worshipful Company of Upholders, mentioned in Chapter 1, also still exists. Membership is a different category — livery rather than trade — and is less directly relevant to the working upholsterer, but the Company's apprenticeship scheme funds new entrants to the trade and is worth knowing about if you're considering taking on a junior.

COMMON MISTAKES · WORKSHOP SET-UP ERRORS THAT CATCH BEGINNERS OUT Treating your back as someone else's problem. The bench height issue is the single largest career-ending injury in this trade. Get it right on day one. Buying cheap LED tubes. A workshop full of CRI 70 lights is a workshop where every fabric looks slightly wrong. The premium for CRI 90+ is small. Pay it. Storing fabric folded. Velvet, especially, is unforgiving. Roll, never fold; even short remnants. Not getting insurance until the first sale. The point at which you need cover is the point at which you start working on a customer's piece, not when you sell it. A chair stored in your workshop overnight is your liability the moment it crosses the threshold.

With the room set up, the next thing you need is the toolkit to fill it. The next chapter walks you through every tool we've ever found useful, every tool we've ever found useless, and — in our opinion — the only correct way to spend your first hundred pounds.
