How to Choose a Sofa
A sofa is the piece a whole room arranges itself around, and often the most you'll spend on a single bit of furniture. It also has to last: most people keep a sofa the best part of a decade. That makes it worth a bit of homework, because the two things that go wrong most often, the wrong size and a frame that sags after two years, are both avoidable.
This guide covers what actually matters: getting it through the door, picking the right size and shape, judging a frame and its fillings, choosing between fabric and leather, and knowing what you should pay. None of it needs a showroom or a sales assistant.
Measure first, fall in love second
The most common sofa regret has nothing to do with looks. It's a sofa that won't fit the room, or won't get into it. Spend ten minutes with a tape measure before you shortlist anything.
- The room. Mark out the sofa’s footprint on the floor with masking tape and live with it for a day. Leave a walkway of at least 45 to 60 cm around it, and check it won’t block a radiator, door swing or window.
- The route in. Measure the narrowest point on the way to the room: the front door, the hallway, any tight turn, the stairwell and doorframes. Check the sofa’s height and diagonal depth, not just its width, since it may need to go through on its side.
- The people. A deep-seated sofa is bliss for lounging and taller people, but leaves shorter sitters perched or unsupported. If in doubt, note the seat depth (the cushion front to back) and compare it against a sofa you already find comfortable.
Size and shape
Size is usually quoted by the number of seats, but seat counts are loose: one brand’s three-seater is another’s large two. Trust the measurements over the label. Here are the common shapes and who each suits.
- Two-seater. The workhorse for smaller rooms, flats and snugs, or as a partner to a larger sofa. Comfortable for two, cosy for a couple.
- Three-seater. The default family sofa and the most-stocked size, so the widest choice and keenest prices. Seats three at a push, two in real comfort.
- Four-seater. A generous sofa for a big living room, or for households that genuinely all pile on at once. Check the room can take the length before you commit.
- Corner sofa. Maximum seating for the floor space, and it defines a zone in an open-plan room. Look for a reversible chaise you can flip to either end as the room changes.
- Sofa bed. Doubles as a guest bed. If it’ll be slept on more than occasionally, the mattress and mechanism matter as much as the sofa itself (see delivery and everyday use, below).
- Armchair. Not a sofa, but worth a mention: a single chair adds a seat and a focal point without the bulk, and pairs well with a two or three-seater.
Frame and fillings: what makes one last
Two sofas can look identical and wear completely differently. The difference is under the upholstery, in the frame and the cushions, and it’s the main thing your money buys once you get past the fabric.
The frame
A kiln-dried solid hardwood frame is the gold standard: it stays stable for decades and won’t warp. Softwood and plywood frames are lighter and cheaper and fine for lighter use, but frames made mostly of chipboard or particleboard are the ones that creak and sag. A long frame guarantee (often 10 to 15 years) is a good sign the maker trusts it.
Seat cushions
- Foam holds its shape with almost no fuss and gives a firmer, more supportive seat. Higher-density foam lasts longer before it softens.
- Feather and down feel luxurious and soft, but they flatten through the day and need plumping to look their best. Lovely if you don’t mind the upkeep.
- Fibre is soft and cheap but flattens fastest, so it’s common in budget sofas and on scatter-back cushions rather than seats.
- Foam wrapped in feather or fibre is the popular middle ground: a supportive core that keeps its shape, with a soft top layer for comfort.
Fabric or leather?
Neither is better outright; they suit different homes. The right call usually comes down to who (and what) uses the room.
Fabric
Warmer to sit on and the widest choice of colour and texture, from flat weaves to velvet. The weave matters: a tight, hard-wearing weave (look for a high "rub count", or a performance or stain-resistant finish) survives family life far better than a loose, delicate one. Removable, washable covers are a real advantage with kids and pets. Velvet looks wonderful but shows marks and needs more care.
Leather
Hard-wearing, ages beautifully and wipes clean, which makes it a favourite with pets and spill-prone households (though claws can scratch it). Full or top-grain leather is the durable, breathable real thing and priced accordingly; "bonded" or "faux" leather is cheaper but peels and cracks far sooner. Leather sits cooler in summer and cold in winter, and offers fewer colours than fabric.
Judging comfort without sitting on it
Buying online, you can’t do the showroom flop test, but the spec sheet tells you more than you’d think.
- Seat depth decides the feel. Deep seats (around 60 cm or more) are for lounging and lying back; shallower seats suit upright sitting, shorter people and formal rooms. Match it to how you actually sit.
- Seat height matters for getting up easily. Lower, softer seats look relaxed but are harder to rise from, which is worth weighing for older users.
- Back type. Fixed backs give a cleaner, tidier look; scatter-cushion backs are softer and more forgiving but need occasional plumping.
- Firmness. Foam seats sit firmer, feather sits softer. Neither is more comfortable in the abstract, so think about which you prefer in a sofa you already own.
Delivery, lead times and everyday use
- In stock vs made to order. An in-stock sofa can arrive in days; a made-to-order one is typically 6 to 12 weeks, sometimes longer. If you need it for a specific date (a move, Christmas, a new baby), order early or filter to what’s in stock.
- Access on the day. Confirm the delivery includes carrying it to the room and unpacking, not just kerbside drop-off, and re-check your doorway measurements before it arrives.
- Sofa beds. If it’ll be a bed more than a few nights a year, prioritise the mattress depth and the mechanism (a proper fold-out sleeps better than a fold-down "click-clack"). A thin foam pad is fine for occasional guests, not for a regular bed.
- Warranty. A long frame guarantee signals confidence in the build; check what it actually covers (frame and springs, usually) versus what it doesn’t (fabric wear, cushion softening).
How much should you spend?
Sofas span an enormous range, and price mostly tracks the frame, the fillings and the fabric quality rather than the badge. Since a good one lasts years, it’s worth buying the best frame you can afford. As a rough guide for a three-seater:
- Under £500, for first flats, occasional rooms and short-term needs. Expect softwood or plywood frames and foam or fibre seats.
- £500 to £1,000, the sweet spot for an everyday family sofa: sturdier frames, better fabric and seats that hold up.
- £1,000 and up, for hardwood frames, feather or high-density foam and premium upholstery, where the difference shows over a decade of daily use.
The same sofa is often a different price at different retailers, and there's nearly always a sale on somewhere, so a sale price is only a deal if it beats what others are charging. That's what we do: we track live prices across the UK retailers we list so you can compare before you buy. For shortlists to start from, see The Best Corner Sofas or The Best 3-Seater Sofas Under £1,000, or browse every sofa we track and filter by size, colour, material and price.
Frequently asked questions
What size sofa should I buy?
Measure the room first and leave a walkway of at least 45 to 60 cm around the sofa. A three-seater is the default for most living rooms; a two-seater suits smaller spaces; a corner sofa gives the most seating for the floor area. Trust the actual measurements over the seat-count label, which varies between brands.
Will my sofa fit through the door?
Measure the narrowest point on the route in (front door, hallway, any tight turn, stairwell and doorframes) and compare it against the sofa's width, height and diagonal depth, since it may need to go through on its side. If access is tight, choose a sofa with removable legs, a modular or easy-build design that ships in sections, or a two-piece sofa.
Which is better, a fabric or leather sofa?
Neither is better outright. Fabric is warmer and offers the widest choice of colour and texture, and washable covers help with kids and pets; choose a tight, hard-wearing weave or a performance finish. Leather is hard-wearing, wipes clean and ages well (though claws can scratch it); full or top-grain lasts far longer than bonded or faux leather, which peels over time.
What makes a sofa last?
The frame and fillings, more than the fabric. A kiln-dried solid hardwood frame stays stable for decades; chipboard or particleboard frames creak and sag. For seats, high-density foam holds its shape with least fuss, feather feels softest but needs plumping, and foam wrapped in feather or fibre is a good middle ground. A long frame guarantee (10 to 15 years) is a sign the maker trusts the build.
How long does a sofa take to be delivered?
An in-stock sofa can arrive within days; a made-to-order sofa is typically 6 to 12 weeks, sometimes longer. If you need it by a specific date, order well ahead or filter to sofas that are in stock, and confirm the delivery carries it to the room rather than leaving it at the kerb.
How much should I spend on a sofa?
For a three-seater, under £500 covers first flats and occasional rooms, £500 to £1,000 is the sweet spot for an everyday family sofa, and £1,000-plus buys hardwood frames and premium fillings that last a decade. Because the same sofa varies in price between retailers and is often discounted somewhere, compare before you buy.
