Vivora Luno Sitting Ball Chair Review (2026)
In-depth review of the Vivora Luno: felt cover, staying put, desk height fit, and whether a ball chair is worth the premium.
Vivora Luno Premium Ergonomic Sitting Ball Chair, Felt, Standard Size
The living-room ball chair: a felt-covered ball that stays put, looks like furniture, and turns desk sitting into light core work.
Our verdict
The Vivora Luno is the best ball chair for desk sitting, because its felt cover solves the two problems that ruin bare-ball sitting: the ball going out of round and rolling away. It looks like furniture, it stays where it is put, and its standard size suits standard desks. It is still a ball, not an office chair: no back, no arms, no height adjustment, so it suits part-day sitting, not a full day in one stretch. Within that honest limit, it is the desk ball to buy.
What we like
- The tight felt cover keeps the ball perfectly round and stops it rolling away, which is the main annoyance of bare-ball desk sitting.
- The cover is machine washable and has a carry handle, so the chair can move between rooms and stay clean.
- The standard size inflates to 22 to 24 inches, which suits standard desk heights without needing a separate base.
What to watch out for
- It has no back support, armrests, or height adjustment, so it suits part-day sitting better than a full workday in one stretch.
- The premium outlay buys the cover and the look, not a different ball underneath, so pure exercisers get more for less elsewhere.
- The felt cover needs washing occasionally, and a stained or worn cover is more visible than a scuff on a bare ball.
Who it is for
Desk workers who want active sitting in a room where a bare PVC ball would look out of place.
The cover is the product
A bare ball used daily slowly goes out of round and rolls at the worst moment, usually when you stand up. The Luno cover holds the ball in shape, adds grip against the floor, and gives a handle for moving it between rooms. The felt also changes the feel: sitting on fabric is cooler and less sticky than sitting on PVC, especially in warm rooms.
Desk fit and daily rhythm
At 22 to 24 inches of sitting height, the standard Luno suits standard desks for most adults, with feet flat and hips level. The right daily rhythm is part-day use: start with short spells, switch to a proper chair when posture slips, and return to the ball later. Used that way, it adds light core engagement without the slumping that comes from forcing a full day on a ball.
How it stacks up
Against the Trideer 65 cm ball, Vivora wins on staying put, looks, and comfort for sitting, while Trideer wins on floor exercises, back stretches, and outlay. Against the Gaiam kit ball, Vivora wins for desk use, while Gaiam wins for structured workouts away from the desk. Against a proper office chair, Vivora wins on movement and engagement, while any good office chair wins on support for a full workday.

Questions, answered
Is the Luno cover washable?
Yes, the felt cover is machine washable. Remove it, wash following the care guidance, and dry it fully before refitting, since a damp cover on an inflated ball traps moisture and smells.
What size Luno should I buy?
The standard size suits most adults at standard desks. Taller users and higher desks should check the larger size, and anyone under about 5 ft 4 in should confirm sitting height before ordering, since a ball that is too tall forces feet off the floor.
Can I exercise on the Luno?
Light seated work, yes, but the cover is made for sitting, not for floor drills. For planks, bridges, and rollouts, use a bare ball like the Trideer or Black Mountain instead, and keep the Luno for the desk.
