The Sunday Sofa Bed: A Deep Seat Sofa to Curl Up On

Some sofas you sit on. Some sofas you sink into. The Sunday, without a doubt, is firmly the second kind. It's the deepest, softest, most unapologetically comfortable sofa bed we've ever made — a sofa designed for the way you actually use your living room. Long films. Slow mornings. Books that take longer than expected. The kind of evenings where nobody quite gets round to moving.

And when the time comes, yes — it's also a bed. But we'll come back to that.

A sofa first. A bed second.

This is the most important thing to understand about the Sunday: it's a sofa first, and a bed second. That's the design brief. The Sunday is absolutely fit for everyday sleeping — it's a proper sofa bed with a proper mattress, not an occasional-use novelty. But if the sleep experience is what matters most to you — if this is going to be your main guest bed, or your own bed in a studio — our Metro and Cocoon sit at the luxury end of the range for sleeping — 18cm mattresses, deeper pocket springs, engineered primarily around the bed. Or if your room is on the smaller side, the Tokyo is our compact space-saver.

The Sunday is for the other scenario — the main sofa in a proper living room, where it gets lived on every day and only occasionally unfolds to host a guest. A deep-seated sofa you genuinely want to sink into, with a proper bed tucked inside for when you need it.

It started with one question.

What if we designed a sofa bed as though it were a proper sofa first?

Most sofa beds are built around the mechanism. The folded bed determines the seat depth. The folded bed determines the back height. The folded bed, in other words, runs the show — and the sofa bit is whatever's left over. That's why so many sofa beds look fine in a showroom but feel wrong the moment you try to settle in. Shallow seats. Upright backs. A sense that you're perching rather than properly sitting.

The Sunday came out of asking the question the other way round. We designed the sofa we wanted to live on — deep seat, soft pillowy cushions, a back tall enough to rest your head against — and then engineered the bed to fit inside that. Not the other way round.

The deep seat, explained

"Deep seat" is one of those phrases that gets thrown around loosely, so let's be precise. On the Sunday, the seat is deep enough that you can properly sit cross-legged on it. Deep enough that two people can lie head-to-foot and watch a film. Deep enough that when you kick your shoes off and tuck your feet up, you're not perching on the edge — you're genuinely in it.

The cushions are filled to feel soft and pillowy on top of a supportive base — the kind of cushion that gives under you and holds you, rather than holding its shape regardless. Pair that with a back tall enough to rest your head against, and the whole thing adds up to a deep seated sofa that's almost impossible to sit on formally. Which is the point.

This is the sofa for —

Big by design

Sunday is our largest sofa bed. Four standard sizes — 2.5-seater, 3-seater, 4-seater, and 5-seater — with custom dimensions available if your room calls for something else. The extra-large is genuinely extra-large: enough sofa for a family to spread out on, enough bed for two adults to sleep properly.

It's not a sofa for a small flat. It wants a proper living room, a snug, a cinema room, an open-plan space where a generous piece of furniture can do what generous furniture does — anchor the room and invite everyone into it.

And the bed

When the bed is needed, the Sunday opens out into a full 2-metre sleeping surface with a 12cm mattress and a choice of three fills — pocket sprung, memory foam, or Reflex (our firmest). It's a proper bed for proper sleep, not an afterthought.

A note on mattress thickness: 12cm isn't the deepest mattress we make — on the Metro and Cocoon we go up to 18cm. But it's the best-quality 12cm mattress you'll find in a sofa bed. Pocket sprung, memory foam, or firm Reflex — built with the same care as our thicker mattresses, just sized to keep the Sunday's seat as deep as it is.

Made the way we've always made them

Every Sunday sofa bed is built to order at our workshop in Nottingham, where we've been making sofa beds since 2007. We cut the timber, upholster the frame, and stitch the cushions ourselves. The fold-out mechanism is by Lampolet of Italy, from their Big Series — a single-movement rotation mechanism that opens out into a full bed. The frame is high-strength cold-drawn steel tube, oven-painted with epoxy powder, on an electro-welded mesh base — with the option of a wooden slatted base if you'd prefer. It's CATAS-certified for domestic and contract use, which means it's rated for the kind of nightly use a hotel would put it through. And we deliver to your door ourselves — because after all that, handing it over to a third-party courier doesn't feel right.

Hundreds of fabrics to choose from, and we'll send up to eight free samples so you can see them in your own light before you commit. Because the difference between a linen that looks great in a showroom and one that looks great in your actual living room is — honestly — sometimes substantial.

Questions people ask

Is the Sunday comfortable to sit on every day?

Yes — that's the whole reason it exists. The Sunday is designed as a sofa first, with a deep seat, soft pillowy cushions, and a back tall enough to properly rest your head against. It's built for daily use as the main sofa in a living room.

How big is the bed inside the Sunday?

Every Sunday mattress is 2 metres long and 12cm thick, with a choice of three fills: pocket sprung, memory foam, or Reflex (our firmest). The mattress width depends on which size Sunday you pick — 120cm (2.5-seater), 140cm double, 160cm king, or 180cm super king (5-seater). More on sofa bed dimensions in our UK sofa bed sizes guide.

What's the difference between the Sunday and the Metro?

Both are proper everyday sofa beds — both can be slept on every night. The difference is where the design emphasis sits. The Metro sits at the luxury end of our range for sleeping: thicker 18cm mattress, firmer support, engineered primarily around the bed. The Sunday trades a little of that sleep-luxury for sofa-luxury — a deeper seat, softer cushions, a more generous sit. Pick the Metro if sleep comfort is your priority; pick the Sunday if everyday sitting is.

Is the Sunday a deep seat sofa bed?

Yes. The Sunday has the deepest seat of any sofa bed in our range — deep enough to sit cross-legged on, tuck your feet up, or lie across. It's designed for people who want a proper deep-seated sofa with the practicality of a bed tucked inside.

What kind of fold-out mechanism does the Sunday use?

The Sunday uses a Lampolet Big Series mechanism, made in Italy. It opens by rotation in a single, smooth movement. The frame is high-strength cold-drawn steel tube finished with epoxy powder, on an electro-welded mesh base — with the option of a wooden slatted base instead, if you prefer. CATAS-certified for everyday domestic and contract (hotel-grade) use. The mechanism's reduced height profile is what lets the Sunday have such a deep seat — Lampolet specifically describe it as designed for sofa beds with a modern, deep-seated design.

Can I try the Sunday in a showroom?

Yes — we have Sunday sofa beds at our London and Nottingham showrooms, but because each is made to order, the specific size, fabric, and mattress fill on display rotates. Give us a call on 0208 4516 999 before you visit and we'll let you know which Sunday is currently in which showroom.

How long does it take to make?

Every Sunday sofa bed is made to order at our workshop in Nottingham. Typical lead time is around 6–8 weeks, though this can vary with fabric availability. Contact us for a current estimate.
