DUMOS Criss Cross Chair
An armless office chair with a seat cut wide enough to sit cross-legged on, in fabric, PU leather and teddy, on casters or on fixed feet, from the family we are known for.
Most office chairs assume a posture nobody keeps. You sit on a foot, you pull a knee up, you turn sideways to the window, and every one of those moves meets an armrest. The criss-cross chair takes the armrests off and widens the seat until a folded leg fits inside its edge, which is the whole of the design. The back is a low, curved shell that supports the lower spine when you sit upright and follows you when you lean, and the base is the five-caster star OSHA asks for under any desk chair.
The family comes in the same shape with different skins: a woven fabric in beige, grey, blue and pink, a PU leather in black and brown that wipes clean, and a teddy pile in pink for a bedroom. The fixed-foot version stands still at a vanity where casters would roll on a rug; the footrest version pulls a rest out from under the seat for the half hour after lunch. Every variant is a row on the page with its own price, and the 300 lb capacity we state is on the card.
What ergonomic means, in OSHA's words
The word ergonomic on a chair is a promise about your body, so here is what the Occupational Safety and Health Administration means by it in its computer workstation guidance. A backrest that follows the natural curve of your spine and supports the lower back; a seat that lets your feet rest flat on the floor or a footrest; armrests, if the chair has them, that let your shoulders relax with your elbows close to your body; and a base with five legs on casters. The desk puts the monitor straight in front of you at least 20 inches away, with nothing stored under it where your legs go. OSHA adds the sentence that matters most: sitting still for a long time is not healthy however good the posture, and the cure is to change position, stand and walk during the day. A chair with lumbar support and a desk that rises are tools for that; neither is a treatment for a back that already hurts, which is a question for a doctor.
Every sentence in this note about safety comes from a named public source. All of them, with the date we read them, are on our updates page.

DUMOS Criss Cross Chair: questions
What people ask us about criss cross chair before they pick a piece.
Does the DUMOS criss cross chair come without wheels?
Yes: the fixed-foot variant stands on four feet for a vanity or a rug, and the rest roll on five casters. Both are rows on this page with their own prices, and the seat and back are the same shell.
How wide is the seat of the DUMOS criss cross chair?
Wide enough for a folded leg, which is the point: the seat pan runs wider than a standard task chair and the armrests are gone, so the edge of the seat is the only limit. The exact width and the seat height range are printed on each variant's page.
Can you sit in the DUMOS criss cross chair for a full working day?
People in the reviews do, and the ones who last the day are the ones who change how they sit in it: cross-legged for an hour, feet down for the next, leaning back for a call. OSHA's sentence applies here as everywhere: no chair makes sitting still healthy, and this one is built for not sitting still.
