Mellow Medium Medium / Three Seater Sofa Bed

The Mellow Medium 3-Seater Sofa Bed is all about bold curves, confident comfort, and effortless versatility. Its sculpted, rounded silhouette taps into the biggest design trend right now—organic shapes that make a statement. The soft lines aren’t just for show—they create a seat that’s as inviting as it looks. Whether you’re hosting overnight guests or just stretching out for the night, the built-in deep mattress means no compromise on sleep.

It's a sofa bed that nails both form and function, with a contemporary edge that fits right in with modern interiors.

Mattresses Designed for Sleeping

The Mellow’s mattress is medium firm, supportive, and genuinely built for sleep—not just occasional guests. Made from advanced, high-resilience foam, it’s engineered to fold smoothly within the sofa frame and spring back to full shape the moment it’s opened. The result? A medium-firm feel that offers proper support for your back and shoulders, night after night. It’s the kind of comfort you'd expect from a real bed—because that’s exactly what it’s made to replace.

Mattress Size and Depth:  
140mm x 1900mm x 150mm (That's slightly bigger than a UK double Bed)

“ We absolutely love our Furl sofas. We have a 3 seater sofa bed and a matching 2 seater sofa. They are so comfortable and everyone who comes to stay and use the sofa bed say how comfortable it is. Both sofas have the aditional storage in the arms which means we can store the duvet and all pillows in the four arms, which is great as we only have a one bedroom flat with limited storage space. ”

“ We have been looking for a good quality sofa-bed for some time and finally found what we were looking for at the Furl store. My daughter can now sleep comfortably and she loves her new sofa bed. As soon as we entered the store, we were very impressed by the excellent quality of the Furl sofa beds. What makes them so special is also the fact that they are delivered in units and assembled once in the house in a very short time, which is fantastic. We wanted a 3 seater sofa bed but the size was the issue for us, as all those we saw in other stores would neither go through our door nor the bay window. Our Furl sofa bed was efficiently delivered and fitted without any problems by experienced and friendly staff. We would also like to say thank you to Becca for making us feel welcome at the store. She was very polite, knowledgeable and helpful throughout the whole process. ”

Thin Mattresses
We Fixed That

It’s hard changing the mindset that sofa beds are comfortable, because at some point, we’ve all had a terrible experience on one.

When we started designing sofa beds back in 2007, improving the the sleep experience was top of our list of priorities.  We identified some of the biggest issues that prevented a quality sleep on a sofa bed, and one by one fixed them.   Our sofa beds have the deepest, most luxury mattresses you'll find on a sofa bed.

A Stylish Sofa and Bed
We Fixed That Too!

We take a no-compromise approach to sofa bed design, there's little point having a sofa bed at all if the sofa is good ( but they often aren't) and the bed is not, why can't you have both? 

Well, thats what we do best, starting from the ground up, the mechanism we build has comfort focused into every element so what you get is a really great sofa you'll never know has a bed hidden inside, and a bed that feels as good as a real bed.
