Cream top looks calm in the office. The cream face and gray edge look much less clinical than the black cushions I considered. The deep rear opening is also exactly as shown in the product photos.

Photographs set the right expectation. The cushion I received has the same cream upper area, gray side wall and lowered front profile shown online. I appreciated that the page did not invent measurements.

The U opening stays genuinely open. The rear channel runs all the way through the back edge rather than ending as a small hole. That was the design detail I wanted and it is easy to see in person.

Una mirada más de cerca, función por función

Create space around your tailbone
A flat chair presses directly beneath the tailbone. This cushion uses a deep, open U-shaped rear channel to leave room around that sensitive area while its broad sculpted surface supports the surrounding seat.

A real opening, not a shallow rear notch
The centered U-channel stays open through the back edge, creating clear space beneath the coccyx area instead of placing another padded layer directly underneath it.

The contour supports around the sensitive spot
Raised rear zones frame the opening while the broad seat surface carries contact around it. The changing side profile makes the intended support pattern easy to see before you sit down.

Sculpted across the full chair surface
The cream upper face forms one connected seating surface with a shallow central basin and rounded outer areas, giving you a shaped alternative to a flat chair pad.

Align the opening, then recheck your chair
Place the U-shaped opening at the back and keep the full cushion supported by a broad, stable seat. Its overall size is approximately 38 × 40 × 8 cm; compare that footprint with your chair before ordering and recheck your feet and desk height after placement.

A coccyx-focused shape without medical promises
The open U-channel is designed to reduce direct chair contact beneath the tailbone area. It is a sitting-comfort aid, not a treatment for sciatica, a coccyx injury, or another medical condition.
Open rear channel
The deep U-shaped opening stays open through the rear edge to create space around the coccyx area.
Broad contoured seat
The surrounding one-piece surface is visibly shaped rather than flat, with raised rear zones and a lower front profile.
Try it on your chair
Individual comfort and chair fit vary, so every order includes ERGOLA's 60-Day Home Trial, and we pay return shipping.

Esta cojín no es la adecuada para todo el mundo
Preferimos que compres lo correcto antes que lo más caro. Algunos casos en los que quizá no sea tu mejor opción:
Cambia la altura al sentarte
Cualquier cojín cambia la relación entre caderas, rodillas, reposabrazos y escritorio. Después de colocarlo, comprueba que los pies estén apoyados y los antebrazos sigan cómodos.
Es un asiento, no un respaldo
El cojín mejora la forma en que te sientas, no el soporte de tu espalda. No sustituye a una silla con un respaldo que dé sujeción.
¿Aún dudas? Con la prueba en casa de 60 días lo pruebas en tu propio escritorio. Si no encaja con tu configuración, devuélvelo y pagamos el envío.

Cream top looks calm in the office
The cream face and gray edge look much less clinical than the black cushions I considered. The deep rear opening is also exactly as shown in the product photos.
A pronounced open-rear contour
This is not a nearly flat chair pad. The raised rear sections and open U shape are quite pronounced, which suited my broad desk chair but may not suit every seat.
Photographs set the right expectation
The cushion I received has the same cream upper area, gray side wall and lowered front profile shown online. I appreciated that the page did not invent measurements.
Measure a narrow chair first
It sits neatly on my wider home-office seat. On our narrow dining chair the footprint felt too generous, so the warning to compare the photographed shape is worth following.
The U opening stays genuinely open
The rear channel runs all the way through the back edge rather than ending as a small hole. That was the design detail I wanted and it is easy to see in person.
Good-looking chair update
My plain task chair looks more considered with the two-tone cushion on it. The contour is visible from the side, yet the color does not dominate the room.
Useful shape, sparse specifications
I like the broad sculpted surface, but I would still prefer published dimensions and care instructions before buying. The product page is honest about those details being unavailable.
Delivery updates were easy to follow
The dispatch estimate was not overly specific, and tracking kept me informed as the parcel moved. It arrived inside the range shown at checkout with the cushion undamaged.
Works best on a flat stable seat
On my flat office chair the full base is supported and the cushion stays where I place it. A curved guest chair was a poorer match, so chair shape matters.
Por fin se acabó el dolor de coxis en mi escritorio
Me fracturé el coxis hace unos años y aguantar una jornada laboral de 8 horas sentado era un suplicio. El recorte realmente quita toda la presión de esa zona. Llevo cuatro semanas y ya no me revuelvo en la silla ni me levanto cada 20 minutos como antes. La base antideslizante es muy firme; no se ha movido ni una sola vez en mi silla de malla.
