About the Sonder
Why choose the Sonder?
The Sonder Sofa brings generous comfort and quiet versatility to spaces where every detail matters. Its relaxed, slipcovered form creates an inviting place to gather, unwind and spend time - equally at home in smaller sitting rooms, garden rooms and flexible family spaces.
Designed to help you slow down and settle in, Sonder makes everyday comfort feel effortless.
The Sonder combines thoughtful craftsmanship with a simpler approach to bespoke upholstery, making it easy to create a sofa that feels naturally at home in your space.
- Relaxed, Considered Comfort: Soft proportions and a tailored slipcover give Sonder an easy, welcoming feel that encourages longer afternoons, slower evenings and everyday connection.
- Made Around Your Home: We can upholster the Sonder in any suitable upholstery fabric, from relaxed linens and classic stripes to richer textures and expressive patterns. Its understated shape adapts naturally to both traditional and contemporary interiors.
- Straightforward Bespoke Upholstery: We guide you through fabric choices, sizing and layout where needed, keeping the process clear, practical and considered from the outset.
- Practical Everyday Living: Fully removable body and cushion covers make day-to-day care simpler and allow the sofa to evolve around your home and lifestyle over time.
- Built for Long-Term Comfort: Traditional upholstery techniques, natural materials and responsible craftsmanship create lasting comfort that remains as welcoming years from now as it does today.
Tailored Design Features for Everyday Living
- Fully Removable Slipcovers: Both the body and cushion covers remove completely. This makes maintenance straightforward while giving Sonder its relaxed, softly tailored character.
- Tailored, Frill or Box Pleat Detailing: Choose between soft tailoring, a gentle peplum frill or a cleaner box pleat finish. Both bring subtle texture and movement while preserving the clean proportions of the frame.
- Made to Your Dimensions: We offer a selection of popular sizes, but we can make the Sonder to virtually any width. Modular layouts, corner configurations and adjusted depths allow the sofa to respond to the way you live.
- Integrated Sofa Bed Option: We can incorporate a sofa bed mechanism with a pocket sprung mattress directly into the base. This preserves the seat height and depth proportions, so comfort and appearance remain balanced.
- Matching Ottoman Available: A coordinating ottoman adds flexibility — whether you need extra seating, somewhere to rest your feet or a more relaxed, informal arrangement.
The Sonder Sofa suits homes where people naturally gather. It creates a softer, more comfortable way to live — somewhere to read, talk, stretch out after a long day or spend an unhurried afternoon together.
Its adaptable shape sits equally well in a compact sitting room, a family space or a garden room where indoors and outdoors flow naturally into one another. With bespoke sizing, upholstery options and flexible configurations, Sonder settles easily into the rhythm of your home.
Perfect Pairings
- Matching ottoman — extends the seating arrangement and adds everyday flexibility.
- Modular corner arrangements — ideal for creating a cohesive seating layout across larger spaces.
We make every Sonder Sofa exclusively in Long Eaton, UK — a place long associated with British upholstery craftsmanship.
The frame uses FSC-sourced, kiln-dried beech and birch hardwood for strength, stability and long-term durability. Seat cushions feature an Origins plant foam core wrapped in recycled fibre and feather down, creating supportive comfort with a softer, more relaxed feel. Back cushions combine recycled fibre and feather down for gentle, sink-in comfort.
We can upholster the Sonder in any suitable upholstery fabric, allowing you to choose the colour, texture and character that feel right for your home.

Cushion interiors
Our standard cushion is an Origins eco-foam core wrapped with Quallofil fibre (made from recycled sea plastic) and European duck feather & down (90/10) seat cushion. Origins foam is derived from plant polymers and sustainable castor oil instead of petrochemical foam.
Our back cushions are a feather, down & fibre mix for soft, supportive comfort.
Of course if you'd like a cushion without feather or foam then we'll happily help you find your ideal option.
A note on our cushions ~ we’ve developed our cushions with longevity in mind. They may feel firm at first, and we recommend giving them 3 months to ‘bed in’ and mould to your body, the way you sit on your sofa and temperature.
We’re confident you’ll love them but if you don’t, we offer a cushion replacement in year one for ultimate satisfaction (and peace of mind).
Single seat and multiple seat cushion options are available. Please note sofa sizes 160cm and below have a single seat cushion unless specified otherwise.
Our frames
Traditional FSC-sourced kiln-dried hardwood frame glued, screwed and dowelled for longevity.
Serpentine steel sprung seat and backs with hessian, coconut & natural latex rubbarised horsehair and jute binds and padding.
We use a wool interliner under each removable cover as an alternative to FR treated barrier cloth.
Access options
The arms on our Sonder sofas are available as a bolt off option as standard. For larger sizes and narrow access points we can make in half also. If you have any queries about access into your home and which size is right for you, please let us know. We will always try to work a solution so you don't have to compromise.

Sonder design notes
I wanted the Sonder sofa to feel like a truly timeless, classic great shape of a sofa.
The design language is simple, transcending trends and letting your choice of fabric sing whether its a slubby linen, strong stripe or romantic floral.
The gentle flare of the arm is a small design detail to make it feel unique, we've included a subtle zipper along the back seam so the loose covers hug the shape and really show off the tailoring involved. Taking the loose covers off is easy when you fancy a change or need to put them in the wash.
A softly sloped sprung rake on the back and sprung seat give optimum comfort and longevity - it's a Long Eaton signature making for a wonderfully comfy sofa.

A few of our favourites
One sofa shape, so many ways to style it. Take a look at a few of our favourite Sonder sofas in their forever homes.
Sonder frill sofa
We used a mix of new Fermoie & repurposed meterage from the brilliant Haines Collection for this gorgeous Sonder frill sofa in Fermoie Abbey stripe.
There was a slight variation in tone between the two batches so we placed one on the back and underneath the cushions, and the other on the 'face'. A lovely example of weaving in circular fabric initiatives without compromising on results.
Width 160cm.
Sonder box pleat sofa-bed
A striped vision of a Sonder box pleat sofa-bed.
We combined 3 different Studio Atkinson stripes on the slipcover and cushions, the sofa-bed frame was made with a bolt off back and arms for ease of access to the loft extension where we had some tight turns and a narrow doorway to navigate.
The single seat cushion keeps proportions feeling streamlined and generous.
Width 180cm.
Sonder tailored sofa
A pair of Sonder tailored slipcover sofas for this young family - we worked with easily washable fabrics from Pure Edit and Romo for ultimate peace of mind, both designed to sit happily with a Wish ottoman in GP & J Baker California. Seen here with an antique rug from one of our favourites, Ourika.
Width 200cm
Sonder fixed back tailored sofa
The brief was deep, comfy and easy to live with for this busy couple who love to travel.
We removed the back cushions but added natural padding for a streamlined profile along the back. The base and chaise cushion can be swapped from side to side for custom comfort.
Width 280cm x 185cm chaise depth.
Sonder frill sofa
A frill slipcover Sonder sofa for this top floor city-centre flat.
Access was simple with the bolt off arms underneath the slipcover (made in the lovely Vanrenen Hanbury Sunda).
We used a single seat cushion to keep the smaller footprint feeling generous.
