15 of the best modular sofas

I often find myself recommending modular sofas – that is, sofas made up from individual components that can be configured in all sorts of different ways – to my interior-design clients. Not only are they extremely flexible, meaning you can make the most of whatever space you have and tailor them to your lifestyle, they can also be rearranged or extended as and when you come to move home. As a result they’re often much more cost-effective and long-lasting than traditional sofas, and they’re the kind of thing you can happily invest in, knowing you’ll be using your chosen design for years or even decades to come.

There’s a vast array of modular sofa systems on the market, so I’ve picked out 15 of the best below. There are options to suit various interior styles, budgets and sitting positions, but all have a timeless, understated aesthetic that’s unlikely to date. What’s more, many allow you to select from a range of pre-determined combinations or design your own using individual sections, and they can form anything from simple two-, three- and four-seaters to super-comfy L-shaped and corner arrangements. I’ve also included a few handy tips to help you find the perfect modular sofa for you and your home – just read on for details.

Tips for choosing a modular sofa

Always start by analysing the space. Size is the most obvious consideration, but it’s not just a case of measuring dimensions – you also need to look at the proportions of the room as a whole. For example, a low-slung sofa might get lost in a high-ceilinged space, whereas a tall sofa could overwhelm anywhere with lower ceilings. If the room is small, try a design with legs to create the illusion of space; boxier sofas, conversely, can look stunning in large open-plan areas. If you’re struggling to picture whether the size or shape of a particular option will work, you could always try marking it out on the floor with masking tape or cardboard before making a decision.

The way you sit and how you intend to use the sofa are key factors, too. How many people does it need to accommodate? And will it be used primarily for conversing or for sprawling out to watch TV? Do you like to lean back, in which case a sofa with a higher back might be more comfortable? Or do you prefer to lean sideways, in which case you might want chunky armrests? If you tend to put your feet up, an L-shaped configuration with a chaise-longue could be a good option, whereas low armrests and open ends work well for those who like to lie out flat. Seat depth can also have a big impact – a larger depth is ideal for curling up in comfort, whereas a smaller depth works well for those who sit in a more upright position and like to be within easy reach of a coffee table.

When it comes to sofa aesthetics, it’s worth bearing in mind not only the decor you have now but also how your tastes and home might evolve. As much as you might be tempted by on-trend green velvet or mustard yellow, it could be worth sticking to neutral colours that will adapt to different styles and spaces. And if you plan on extending your sofa to suit future rooms, focus your search on systems that have already been around for a few years (HAY’s ‘Mags’ and more relaxed ‘Mags Soft’ are good examples), as there’s a good chance they’ll still be on the market when you come to buy additional modules.

Materials and construction methods have a major impact on the lifespan of a sofa, so check what the frame is made of and how it’s built (the most durable are glued and screwed together). Consider the filling, too – fibre and feather fillings are sink-into comfy but will need regular plumping; foam, on the other hand, is generally firmer but keeps its shape for longer. Sofas are definitely pieces to prioritise when it comes to allocating budget, as they have a big impact on daily life and there’s generally a direct correlation between quality and price, but if money is tight then IKEA’s ‘SÖDERHAMN’ system is a great option. It’s stylish and comfortable, and the covers can be removed if they need washing or replacing – ideal if you have children or pets (or if you’re prone to spilling food and drink, like I am!). You can even customise it with covers and legs from companies such as Bemz for an individual, high-end look.

Finally, I know it sounds obvious, but do make sure the design will fit through any narrow doors or hallways before ordering. It’s less of an issue with modular sofas than with conventional designs, but it’s still better to be safe than sorry!
