Which SeatNest version is included?

Choose Mystery Black, Dual Grey, Beige / Grey, or Grey / Green. All four are documented SKUs with the same sculpted form and central opening; only the cover colour distribution changes.

What is SeatNest made from?

Product documentation identifies a memory-foam core. It does not state the foam density or the exterior textile composition, so no more specific material claim is made.

What are the cushion dimensions?

Overall dimensions are 15.75 × 13.39 × 3.15 in (approximately 40 × 34 × 8 cm). Product documentation does not include weight or a load rating. Its complete base must rest on a stable chair seat without overhanging or shifting.

Can I adjust the height or firmness?

No. SeatNest is a fixed one-piece cushion with no height, angle, or firmness mechanism. Product documentation does not include a firmness grade for the memory foam.

Is the cover removable or machine washable?

The product documentation does not confirm a removable cover or provide washing instructions. Follow any care label supplied with the product and do not assume that either the cover or foam core can be machine washed.

What is the return policy?

Every order includes the 60-Day Home Trial: ERGOLA pays return shipping and refunds the item price within 5 business days of the return arriving. EU statutory consumer rights remain unaffected.

Quelques avis récents sur le produit.

SeatNest adds a clearly defined basin. The raised sides and rear frame a lower middle area, so it feels visually different from a flat slab. The black color works well on my office chair.

Memory core without inflated specifications. The page confirms a memory-foam core but does not invent a density or firmness grade. That is the right balance of useful information and restraint.
Marieke V.
Fixed shape keeps things simple. There is no pump, dial or insert to tune. The sculpted form is built in, which is exactly why I chose this over more complicated seat accessories.

Person seated on the black SeatNest Memory Cushion on an office chair

Sculpted seating layer

A contoured memory-foam surface for an existing chair

SeatNest combines a raised outer profile with a central rear opening in one cushion. All four verified colour versions share the same fixed memory-foam shape with no levers or adjustment parts.

4 verified coloursMemory-foam coreCentral rear openingFixed sculpted shape

Top view of the SeatNest central rear opening and surrounding black cushion surface

Open rear geometry

A central opening built into the cushion

The elongated opening runs through the rear-center portion of the cushion. It is part of the fixed form rather than a removable insert or adjustable component.

Four colour optionsRaised side and rear contours

Side view showing the raised SeatNest contours and lower front edge

Contoured surface

Raised edges frame a lower center

The top surface rises around the sides and rear while the front edge stays lower. Product documentation does not include measurements for these contours, so no height or fit range is claimed.

Memory-foam coreLower front edge

No mechanism

Place the one-piece cushion on a stable seat

SeatNest has no assembly, powered parts, or adjustment hardware. Position the complete cushion on a stable chair seat and make sure it cannot overhang or shift before sitting.

Chair-top use

A portable layer for seated work at home or in the office

The cushion can be moved between compatible seats without tools. Although overall size is approximately 40 × 34 × 8 cm, no universal chair-fit range is published, check that it rests completely on the intended seat before each use.

Close-up of the black SeatNest surface, stitched seam, contour, and central opening

Simple construction

One memory-foam form with clearly stated unknowns

The source identifies a memory-foam cushion and shows the full sculpted exterior. It does not document the foam density, cover composition, care method, or load rating, so those details are not inferred.

Memory-foam core

The product title identifies memory foam but does not state density, rebound timing, or firmness grade.

Fixed sculpted profile

Raised outer contours, a lower center, and a rear opening are formed into the cushion without mechanical adjustment.

Exterior details disclosed honestly

A sewn exterior is visible, but product documentation does not specify its textile composition or confirm that it is removable.

Un point honnête sur l’adéquation

Ce coussin ne convient pas à tout le monde

Nous préférons que vous achetiez ce qui vous convient plutôt que le produit le plus cher. Quelques cas où ce ne serait peut-être pas le meilleur choix pour vous :

Il modifie votre hauteur d’assise

Tout coussin modifie la position relative des hanches, des genoux, des accoudoirs et du bureau. Après installation, vérifiez que vos pieds sont soutenus et vos avant-bras confortables.

C’est une assise, pas un dossier

Le coussin améliore votre façon de vous asseoir, pas la façon dont votre dos est soutenu. Il ne remplace pas une chaise dotée d’un dossier porteur.

Encore un doute ? Avec l’essai à domicile de 60 jours, vous l’essayez à votre propre bureau. S’il ne convient pas à votre installation, renvoyez-le : le retour est à nos frais.

SeatNest adds a clearly defined basin

The raised sides and rear frame a lower middle area, so it feels visually different from a flat slab. The black color works well on my office chair.
