Shopping for a sofa throws a lot of words at you. Modular, chaise, 2 corner 1, tech, snuggler, U-shape… It's easy to end up scrolling through hundreds of sofas without being sure which kind you actually need.
This guide sorts the main sofa types into plain English: what each one is, roughly how much room it takes, and who it tends to suit. Once you know which shape fits your room and your household, choosing the colour and fabric is the fun part.
Sofa types at a glance
Here's the quick version. Scroll down for more detail on each one.
| Type | Best for | Worth knowing |
|---|---|---|
| 2, 3 or 4-seater | Most rooms; easy to place and move | Pairs well with a chair or second sofa |
| Corner / L-shape | Families, film nights, open-plan rooms | Needs the right left or right hand layout |
| U-shape | Big rooms and big households | Takes a lot of floor; measure carefully |
| Modular | Flexible layouts, moving house, tricky access | Price can climb as you add sections |
| Chaise sofa | Stretching out without a full corner | Chaise side is fixed on some designs |
| Recliner / power recliner | Feet-up comfort every evening | Needs space behind and in front |
| Tech sofa | Home cinema fans and gamers | Needs a socket nearby |
| Sofa bed | Guest rooms, flats, occasional overnight guests | Check the open length |
| Loveseat | Small spaces, bedrooms, extra seating | Seats one generously or two snugly |
2, 3 and 4-seater sofas
The straight sofa is still the most popular choice, and for good reason. It's simple to place, fits against a wall or floats in the middle of a room, and is the easiest shape to get through a front door.
2-seater sofas: usually somewhere around 150–180cm wide. Ideal for flats, snugs and smaller lounges, or as a second sofa.
3-seater sofas: roughly 190–230cm wide. The all-rounder for most UK living rooms, with room to lie down.
4-seater sofas: often 230cm or more. A long, statement sofa for bigger rooms, without the depth of a corner.
Sizes vary a lot between ranges, so always check the measurements on the product page. If you're torn between the two smaller sizes, our guide to choosing between a 2 and 3 seater goes through it step by step.
Corner, L and U-shaped sofas
Corner and L-shaped sofas
A corner sofa wraps around a corner of the room, seating more people in less floor space than two separate sofas. The description tells you the layout: "2 corner 1" means two seats on one side of the corner and one on the other. They're brilliant for families and open-plan rooms, where the sofa can double as a room divider.
The main thing to get right is which side the longer run goes. Our guide to left or right hand corner sofas explains how to work it out. Browse corner sofas and L-shaped sofas.
U-shaped sofas
A U-shape adds a third side, either with two corners or a corner and a chaise. It creates a sociable, enclosed seating area that's perfect for big families and big rooms, but it takes up a lot of floor. Our U-shape sofa guide covers sizes and the rooms they suit.
Modular sofas
A modular sofa is made up of separate sections, such as arm units, armless seats, corner pieces and chaises, which you put together to make the shape you want. Need a corner now and a straight sofa after you move? Rearrange or add pieces.
Our Cloud modular corner sofa (pictured at the top of this guide) is a good example, built from arm, armless and corner sections. Because the sections are smaller than a whole sofa, they can also be easier to get up narrow stairs or through a tight hallway. The one thing to watch is cost, as each extra section adds to the price. See all our modular sofas.
Chaise sofas
A chaise sofa has one extended seat at the end, long enough to put your legs up. It gives you lots of the lounging room of a corner sofa while taking up less width, so it's a good middle ground for medium-sized rooms.
Fixed chaise: the chaise is built into the sofa on one side, so you choose left or right when you order.
Chaise footstool: some ranges, like our Rosie and Wilmslow corner sofas, offer an open end with a separate chaise footstool you can move or use as extra seating.
As with corner sofas, think about which side the chaise should be on so it doesn't stick out into a walkway or block a door.
Recliner and tech sofas
Recliner sofas
Recliner sofas have one or more seats where the back tips and a footrest rises. Manual recliners use a lever or handle; power recliners work at the touch of a button and often add power headrests and USB charging. Corner recliners can give every seat its own footrest.
The Sorrento modular corner combines power recliner seats with a handy console for drinks and remotes.
Measure with the seats fully reclined, allowing space behind the back and in front of the footrest. You'll find manual and power styles in our recliner sofas.
Tech and cinema sofas
Tech sofas take the recliner a step further, adding features such as consoles with cup holders, charging points, lighting and even built-in speakers. They're made for film nights, sport and gaming.
The Empire tech sofa puts a console between two power recliners, with lighting glowing underneath.
Plan for a nearby socket before it arrives. Browse our tech sofas.
Sofa beds
A sofa bed is a sofa by day and a bed at night, usually with a fold-out mechanism hidden under the seat cushions. It's the answer for spare rooms that double as an office, small flats and anyone who has family to stay a few times a year.
The Swift sofa bed looks like a classic 2-seater and pulls out when guests stay over.
Open length: measure the room with the bed fully open, plus room to walk round it.
How often it's used: nightly use needs a better mattress and mechanism than the odd guest.
Corner sofa beds: some corner sofas have a bed built in, so you don't lose seating to get a guest bed.

Loveseats and matching sets
Loveseats
A loveseat, also called a snuggler or 1.5 seater, is wider than an armchair but smaller than a 2-seater. It seats one person generously or two people snugly, which makes it perfect for bedrooms, conservatories and small lounges, or as a cosy partner to a bigger sofa. See our loveseats.
Matching sofa sets
Buying a sofa with a matching chair, loveseat or second sofa from the same range is the easiest way to get a pulled-together room. Popular combinations are a 3 and 2 seater, or a sofa plus one or two chairs.
A Franco sofa and matching chair give the room a calm, coordinated look.
Browse matching sofa sets, or pick pieces from one range to build your own.
Arm and back styles
Once you've picked a type, the arms and back decide the character of the sofa. A few names you'll come across:
Chesterfield: deep-buttoned, rolled arms, a traditional look. The Cavendish pairs Chesterfield-style arms with a softer pillow back.
Scroll arms: arms that curl outwards, common on country and cottage-style sofas.
Square or track arms: straight, neat arms that look modern and give you a bit more seat width for the size.
Pillow back: loose, plump back cushions for a relaxed, sink-in feel. They need plumping now and then.
Formal or fixed back: a tailored back that stays neat with very little effort.
Our tip: two sofas with the same overall width can have quite different seat widths. Slim or square arms leave more room for sitting than chunky rolled arms, so compare the seat measurement too if space is tight.

Common questions
What's the difference between a corner sofa and an L-shaped sofa?
Very little. Both turn a corner. "L-shape" is often used for sofas with one long side and one short side, or a chaise, while "corner sofa" covers any layout that wraps round a corner.
Which type of sofa is best for a small room?
A 2-seater, a loveseat or a compact chaise sofa usually works best. Choose slimmer arms and raised legs to keep the room feeling open, and a sofa bed if you also need a guest bed.
Is a modular sofa worth it?
If you move house often, have tricky access, or like to change your layout, yes. If you're sure of the shape you want and it'll stay put, a fixed sofa can be better value.
Do recliner sofas need to be away from the wall?
Most need some space behind them so the back can tip. How much depends on the sofa, so check the reclined depth on the product page before you place it.
