DEELYA is for anyone who spends time sitting and feels that prolonged immobility eventually takes its toll.

It is suitable for:
• work, in the office or telecommuting
• at home, for reading, studying, or concentrating
• occasional or prolonged use
• and this, intergenerationally.

When seated for prolonged periods, movements often become rarer and more repetitive. DEELYA introduces discreet movement into the seating experience and dynamic comfort: support points continuously vary, without requiring conscious effort.

A classic cushion mainly changes the firmness or surface comfort. As an active seating support, DEELYA goes further by introducing discreet and continuous movement. The support points evolve throughout the day to offer premium and dynamic comfort, without changing your chair or your habits.

A sitting ball replaces a chair, takes up space, and often requires more balance. DEELYA sits on an existing chair. The movement remains discreet, with complete stability, for use in the office or at home.

No. DEELYA is not a medical device. It is an active sitting support designed to introduce discreet movement into prolonged sitting, without therapeutic promise or postural correction.

DEELYA is adjusted on two levels.

By air, with the supplied pump. More air for a firmer feel, less air for a softer feel.
By the side. The support has two sides, a smooth side, an embossed side. You choose, you turn it over throughout the day.

Yes. Placed on a flat base, DEELYA maintains broad contact with the chair. Movement remains discreet: support points evolve smoothly, without any feeling of instability.

No. You sit as usual. Your body weight is enough to activate the micro-movement, without any instruction or effort.

Very little. DEELYA is ready to use from the first time you sit on it. It provides a smooth experience when you sit down, and its movement naturally becomes more discreet with continued use.

No. The movement is discreet and continuous. The body's weight is enough to activate it — without requiring any effort. You sit down, and you forget it's there.

Yes, if needed. DEELYA continuously makes micro-adjustments, often unconsciously. It also offers the possibility to vary pressure points voluntarily, or to allow the pelvis to move back and forth, from side to side.

Yes. Even a comfortable chair gradually becomes static when you sit for a long time. DEELYA keeps the pelvis free and provides variable support, without changing the chair itself.

Yes. Telework and the office are the primary contexts for which DEELYA was designed. This specific scenario, in fact, is what inspired our thinking.

DEELYA fits on most flat-seated chairs:
• office chairs, including those with wheels
• dining room, kitchen, and home office chairs
• armchairs with flat seats, stable stools

The only exceptions are heavily curved seats, very narrow stools, and soft surfaces where the support cannot find stable footing.

DEELYA measures 39 cm in diameter. It may slightly overhang the chair without affecting stability or use.

DEELYA is designed to remain perfectly stable, including on office chairs with castors or on smooth surfaces. Your body weight naturally holds the object in place, while the flexibility of the internal support allows it to precisely conform to the shape of your seat for optimal adherence. As for the finishes, the upholstery fabric cover is adjusted to the millimeter by our seamstresses to fit the support without creating creases or material slippage. You keep your habits and your seat, with the added benefit of movement.

No. DEELYA weighs approximately 1.1 kg and has an integrated handle. It can be easily moved from one room to another, from the office to the living room, without needing to be inflated or set up each time it's moved.

Yes. Several DEELYA can coexist—from one room to another, from one workstation to another, from shared use to individual use. The understated colors hold together visually, whether they are identical or mixed.

The support is made of high-density soft PVC, filled with air. Phthalate, BPA, lead, and latex-free. 100% recyclable material

The textile part is made of polyester and comes in two fabrics:
• heathered for Seren, Bora, Terra — OEKO-TEX certified

DEELYA is a seating accessory for static use at home, in the office, or in a shared space. It is not suitable for:

• in a car, for driving — it alters the seating position and the positioning of the seatbelt
• as a seat for toddlers — DEELYA is not a childcare device
• as a toy — use by a child requires adult supervision
