A few recent product reviews.
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.

Coccyx-focused comfort
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.
Deep open U-channelCoccyx-area clearanceBroad sculpted surfaceCream and gray finish
Tailbone clearance
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.
Deep open U-shaped coccyx channelRaised rear contour
Surrounding support
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.

Everyday seating
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.
Broad sculpted seating surfaceDesigned for broad stable chair seats
Fit comes first
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.
Honest comfort support
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.

Individual comfort and chair fit vary, so every order includes ERGOLA's 60-Day Home Trial, and we pay return shipping.

Honest Fit Check
This cushion isn't right for everyone
We'd rather you buy the right thing than the most expensive thing. A few cases where this might not be your best match:
It changes your sitting height
Any cushion changes the relationship between your hips, knees, armrests, and desk. After placing it, check that your feet are supported and your forearms still rest comfortably.
It's a seat, not a backrest
The cushion improves how you sit, not how your back is supported. It isn't a substitute for a chair with a supportive backrest.
Still not sure? With the 60-Day Home Trial you can try it at your own desk. If it doesn't fit your setup, send it back and we pay the return shipping.

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.

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.

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.

Finally no more tailbone pain at my desk
I fractured my coccyx a few years ago and sitting through an 8-hour workday was miserable. The cutout actually takes all the pressure off that spot. Four weeks in and I haven't shifted or stood up every 20 minutes like I used to. The non-slip base is solid — it has not moved once on my mesh chair.
