Kelva Ergonomic Mesh Task Chair
Ergonomic support that sets itself up for you
The Kelva is an ergonomic mesh office chair built for people who sit and work for most of the day. There are no tension knobs to fiddle with: its synchronised mechanism reads your body weight and adjusts the recline resistance automatically. As you lean back, the seat and backrest move together in proportion, so your feet stay planted and your posture stays open.
Breathable back, supportive lower spine
The black mesh backrest lets air move freely, so you stay cool through long sessions. Adjustable lumbar support, with 80mm of travel, sits exactly where your lower back needs it.
Fits you, not the average person
A sliding seat adjusts the depth from 465 to 525mm, giving shorter and taller users proper thigh support. The Class 4 gas lift gives a 460–590mm seat height range, and the 3D armrests move up and down, forwards and back, and pivot inwards, keeping your shoulders relaxed whether you're typing or on a call.
Comfort that lasts
The moulded foam seat keeps its shape far longer than cut foam, and it's upholstered in a hard-wearing fabric made from 100% post-consumer recycled polyester. Soft-tread 65mm castors glide quietly and are kind to hard floors.
Built to commercial standards
The Kelva is tested to EN 1335 and ANSI/BIFMA X5.1 office chair standards, meets UK fire regulations (BS 7176, BS 5852, EN 1021), and comes with a 5-year guarantee.
Delivered next day, fully assembled
No flat-pack, no tools. Your Kelva ergonomic office chair arrives the next working day, ready to sit in.
