What’s the difference between a sleeper sofa and a sofa bed? If you’re in the UK, you might actually be hearing the term “sleeper sofa” for the first time.

This is because “sofa sleeper” is more of an Americanism than anything else. But no matter what side of the Atlantic you’re on, these terms are often muddled and used interchangeably, especially when it comes to online shopping.

But there is a difference between the two: a sleeper sofa has a full pull-out bed with a mattress, while a sofa bed usually folds down by lowering the back or rearranging cushions. In short, a sofa sleeper contains a hidden mattress, while a sofa bed - in technical terms - doesn’t.

We believe this distinction matters, because at Furl, our designs are sleeper sofas in the truest sense: real beds, tucked inside beautifully made sofas. Built for comfort, engineered for sleep, and designed to last.

Let’s take a closer look at the key distinctions between space-saving sofa beds and premium sofa sleepers.

The Sleeper Sofa: A Classic Mechanism

The sleeper sofa is, at its core, a sofa that hides a full bed within. You lift the cushions, unfold a metal frame, and there it is: mattress, support, the works. Often, it's a pull-out design.

This isn’t a new idea – the sleeper sofa has been a staple of multifunctional living for decades. And while the clunky versions of the 90s may spring to mind, today's models are sleeker, lighter, and far more considered.

At Furl, we design sleeper sofas that are actually built to be slept on every night. With proper mattresses up to 18cm deep, robust internal frames, and thoughtful ergonomic support, our designs go far beyond occasional use. Whether it’s our Tokyo Sofa Bed or our new London Sofa Bed, each features a real bed inside – and we mean that quite literally.

What is a Sofa Bed? (And why Furl is an Upgrade)

A sofa bed, by contrast, doesn’t conceal a mattress. Instead, it becomes the mattress.

Rather than hiding a metal frame, the structure transforms – usually by folding flat or reconfiguring the cushions to create a sleeping surface. It’s simpler, but it’s not always the most comfort-friendly.

This is because the comfort depends entirely on the design: without a separate mattress, the seat cushions are the bed – which can be a strength or a weakness. When well-made, the result is a consistent, supportive surface that suits short stays or quick naps.

But - not all sofa beds are created equal. Many are built with occasional sleep in mind: a convenient place for guests, but not something you’d want to sleep on every night. At Furl, we approach things differently.

We design sleeper sofas that act like proper beds, engineered to deliver comfort night after night. That means thick, supportive mattresses (up to 18cm deep), no central bars or dips, and easy, intuitive mechanisms that make daily use effortless.

So while we use the term “sofa bed” (because that’s what our customers search for), what we actually sell are sleeper sofas. And that distinction matters, especially if - like us - sleep quality isn’t something you’re willing to compromise on.

So Which Is Better?

If your priority is real, consistent, restful sleep – there’s a clear winner.

While sofa beds offer simplicity and style, they’re not built for every night. Sleeper sofas, especially the kind we build at Furl, are engineered for exactly that, with real mattresses and solid support that guarantee comfortable sleep, night after night.

If you’re furnishing a space that demands both form and long-term function: perhaps a studio flat, a guest room, or even your main bedroom – a Furl sleeper sofa is the smarter choice. We’ve taken the classic pull-out concept and redefined it to meet modern needs: proper depth mattresses, ergonomic structures, and effortless mechanisms.

Our Take

At Furl, we believe that furniture shouldn’t just work. It should feel right. So if you want the familiarity of a traditional pull-out, we’d hedge our bets that a sleeper sofa might just be your perfect match. On the other hand, if you crave modern elegance with intuitive function, the sofa bed holds the edge.

Every Furl sleeper sofa includes:

- A real mattress (up to 18cm deep, Reflex or pocket spring options)

- 60 Days. Zero Risk. 100% Comfort.

- Free Home Measure Service

- 50% Deposit to Order

- Handmade-to-order builds, with hundreds of custom options

- UK-based design, manufacturing, testing, and delivery by people who care

Our sleeper sofas aren’t made for the odd overnight guest, they’re made for people who actually sleep on them. Every night. So go ahead and explore the Swan, the Tokyo, and the rest of our collection, and discover what daily comfort really feels like.
