Your back pain may not come from standing. It may come from sitting.
At first, everything is fine. Then after 30 minutes, you start to change position, lean on one side and then on the other.
Pressure in the coccyx, discomfort in the hips, low back stiffening: the problem can be aggravated by hours spent on a surface that
does not distribute your weight evenly.
SITÉO™ transforms your chair into an ergonomic seat
with high-density foam and a sculpted shape designed to redistribute pressure.
Coccyx comfort
🍑 Your coccyx should not bear your weight all day long
When you sit for several hours, part of the pressure can concentrate around the pelvis and the coccyx.
That's why SITÉO™ has a
specially designed cutout at the back of the cushion.
Your tailbone rests over an open space, while your weight is spread more evenly across your buttocks, hips and thighs.
🍑 Sensitive Coccyx
🪑 Discomfort after several hours
🦴 Sensitive lower back
🚗 Long journeys
You don't just make your chair softer. You change the way your body rests on it.
Prolonged sitting
🦴 Sciatica, lower back, hips: when sitting becomes a struggle
SITÉO™ has a sculpted shape designed to keep the hips more stable and to better distribute the pressure.
⚡ Sciatica
More even pressure distribution can make sitting more comfortable.
🍑 Sensitive Coccyx
The rear cutout reduces direct contact.
🦴 Lower back
A more stable seat helps reduce slouching.
🪑 Hips
The contours further distribute the weight.
🦵 Thighs
The contoured edges support your legs more naturally.
SITÉO™ remains a comfort accessory and does not constitute a treatment of sciatica.

Your chair may not change.
But the way you sit can.
You work sitting, you drive sitting, you eat sitting, you watch TV sitting.
If all these hours start to be felt in the coccyx, hips or lower back, it may be useful to start by changing what is directly between your body and your seat.

Frequently Asked Questions
Is SITÉO™ right for you?
A traditional cushion mainly adds padding beneath your body.
SITÉO™ has a
rear cutout designed to leave space around the tailbone
in order to reduce the direct contact of this area with the center of the seat.
SITÉO™ can be used as a comfort accessory when the extended sitting position becomes unpleasant.
It does not treat the cause of sciatica. If pain is severe, persistent or accompanied by significant weakness or numbness, seek medical advice.
Yes, it is one of the main uses of SITÉO™. Its foam and shape are designed for long sitting periods.
Yes. Just make sure the extra height does not interfere with your access to the pedals, your driving position or the correct placement of your seat belt.
It can bring more comfort when the pelvis, hips or lower back become sensitive to a firm seat.
If you are at risk of pressure sores or have a specific medical condition, a specialized medical cushion may be needed.
No. SITÉO™ seeks a balance between comfort and support thanks to its high density memory foam.
High-density foam is designed to retain its shape. Its actual durability depends on use, the weight it supports and how it is cared for.
A non-slip base is provided to help the cushion stay more stable on the seat.
Yes. The outer cover is removable. The foam core must be cleaned separately and must not go in the washing machine.
SITÉO™ measures approximately

Essential for my long-haul deliveries. With 10 to 12 hours a day at the wheel...
Indispensable for my long-term deliveries. With 10 to 12 hours a day driving my semi-trailer, the bottom of my back and thighs were always numb. Since I put the SITÉO on my seat, the vibrations of the road are super well cushioned and the cutting at the back relieves the pressure on the coccyx. The non-slip base does not slide at all while driving. A purchase that is worth every cent!

Indispensable for my long journeys by truck. I often make the Quebec-Montreal road and the stiffness in my hips became unbearable. This cushion spreads the pressure very well and does not slide on the bench thanks to its non-slip base. Very satisfied!

A blessing for my hip osteoarthritis.
A blessing for my hip osteoarthritis. My daughter bought it for me for my rigid kitchen chair. The foam is firm enough to support me well, but mellow enough to remove the pressure points. I can finally eat as a family without trying to get up after 20 minutes.

Turns a bad chair into a comfortable seat.
Turns a bad chair into a comfortable sitting. My computer chair had become too hard. Rather than buying a expensive one, I tried SITÉO. The cut for the coccyx changes everything. Very good investment.
