## Description

Replacement raise, lower, tilt mechanism for office chair

Review: Tengo una silla Newskill Horus Zephyr y le funcionó perfectamente, merece la pena! Después de 5 años con mi silla se rompió la palanca de la inclinación, y encontré este con las medidas perfectas para su recambio! Tardó una semana en llegar
Review: desertcart added a flag to this that it is frequently returned because of the size. I used the dimension sheet in the product image listing and that helped me to see that this would have been a perfect fit. As stated by other reviewers, I also purchased a hammer to get the old base off and very easily installed this in a few minutes. Does its job well and fit within my budget (£25). I've seen quite a few reviews talking about the welds having a 2 year life cycle. I guess I'll be back in two years (or less depending) to report my finding.

*by Y***N on 3 June 2025*

J’ai acheté ce mécanisme BiMi pour remplacer celui d’une chaise de bureau haut de gamme dont le système d’inclinaison était complètement usé. Résultat : installation rapide et efficacité immédiate. Ce produit a parfaitement rempli son rôle. ✅ Les points forts : Compatibilité parfaite avec ma base de chaise (entraxe standard 150 x 255 mm). Pièce lourde et solide, le métal inspire confiance. Les mouvements sont fluides, l’inclinaison est naturelle, et le levier de réglage fonctionne sans accrocs. Verrouillage simple et efficace : la position choisie reste bien bloquée. L’installation a pris moins de 15 minutes avec seulement 4 vis (non fournies mais réutilisées de mon ancienne pièce). 💡 Grâce à ce remplacement, j’ai évité d’acheter une chaise neuve. Pour un peu plus de 40 €, ma chaise est repartie pour plusieurs années d’usage. 🔧 Je recommande fortement ce mécanisme si : Votre chaise a un pied solide mais l’inclinaison est morte. Vous entendez des craquements ou si la position ne tient plus. Vous voulez un confort équivalent à une chaise neuve sans vous ruiner.
