For whom?

To those who spend much of their day sitting — and who feel that prolonged immobility eventually takes its toll.

To those who have looked for an alternative without finding the right one: a ball too cumbersome, a seat too expensive...

To those who want to sit better, without replacing everything.

The body regains fluidity

In use, the difference is as subtle as it is tangible. You feel it, and it lasts. The seat remains stable, without tilting.

Under the body's weight, the support stays firmly in place and creates a slight mobility — a micro-movement that responds to adjustments. The pelvis remains free, and the pressure points redistribute. The seat supports without restricting.

After a few minutes — at the office, while reading, in a meeting — you no longer think about it. That's probably the best sign.

Two settings — one adaptable seat

One DEELYA, multiple seating options

Each person adapts their seat and modifies it. Through the air. Through the chosen side. According to preferences, according to the moment.

By air

More air for a firmer feel. Less air for a softer feel. The volume is adjusted using the pump provided. Once set, you can forget about it.

On the face

One smooth side. One textured side. Underneath the body, the sensation differs. You flip DEELYA in an instant, depending on what you want to feel.

Ils partagent leur expérience

“ Je pensais choisir un ballon, mais DEELYA m’a semblé plus simple à vivre : discret, qualitatif, et sans prendre toute la place. ”

Alain — Open space

“ On l’oublie vite. On s’assoit, on se concentre sur ce qu’on a à faire, et le mouvement reste là, discrètement. ”

Marie — Domicile

“ Depuis que j’utilise DEELYA, je me surprends à m’asseoir autrement. Ce n’est pas volontaire, c’est venu tout seul. Et je n’ai pas eu besoin de changer ma chaise. ”

Hélène — Domicile, lecture et travail

“ Je l’utilise tous les jours au bureau. Même après plusieurs heures, l’assise reste agréable, avec ce léger mouvement qui évite de rester complètement figé. ”

Hugo — Bureau, 8h/jour

Usage and Compatibility

DEELYA is designed for chairs with a flat seat: office chairs including those with wheels, dining chairs, and armchairs with a flat seat.

It is less suitable for very curved, very narrow, or heavily padded seats.

No assembly is required. You place it, sit down, and the movement naturally adjusts with your body weight.

The support stays securely in place.

Material and craftsmanship

DEELYA is designed in France and manufactured in Europe.

The DEELYA base is made in Italy from high-density PVC, free of phthalates, BPA, lead, and latex. The material is 100% recyclable.

The textile part is crafted in Portugal by seamstresses specialized in upholstery. It is hand-stitched from an upholstery fabric chosen for its feel, durability, and resistance to wear.

Settings and maintenance

DEELYA adjusts in two ways.
- By air: with a little less air, the feel is softer. With more air, it becomes firmer. The provided pump allows for easy adjustment of the air level.
- By side: the base has two sides, a smooth side and a textured side. You choose, you flip it over, you adjust it according to your preference.

The base can be cleaned with a soft, slightly damp cloth. The textiles are easily removable for separate maintenance, according to the instructions on the maintenance page.

Kit contents and delivery

A complete DEELYA includes: a seating base, one or more textile colors depending on the chosen composition, an inflation pump, a tool to remove the valve, and a user manual.

Orders are shipped from our logistics center in Haute-Savoie, to France and served European destinations. Delivery terms, times, and returns are detailed on the Delivery & Returns page.

Frequently Asked Questions

Is DEELYA stable?

Yes. Placed on a flat seat, DEELYA maintains optimal contact with the chair. The movement is there, discreet: the points of support evolve smoothly, without any sensation of instability.

Does it fit all chairs?

DEELYA is suitable for the vast majority of flat seats—office chairs, dining chairs, and armchairs with flat seats. It is less suitable for very curved, very narrow, or heavily padded seats.

Can it be used all day?

Yes. DEELYA is designed to support prolonged sitting and offer dynamic comfort. The movement remains discreet and naturally follows the body's adjustments throughout the day.

Can the sensation be adjusted?

Yes. The air level allows for adjusting the feel: a little less air for a softer seat, more air for a firmer feel. The base can also be used smooth side up or textured side up, depending on the desired sensation.

Is DEELYA easy to transport?

Yes. DEELYA weighs about 1.1 kg and has an integrated handle to be carried with one hand. It can follow the day from one place to another — office, remote work, living room — without inflation or setup at each move.

Is there an adjustment period?

Very little. DEELYA can be used from the very first sitting. It feels fluid when you sit down, and then the movement naturally becomes discreet with use.
