BiMi 50137 Replacement Office Chair Tilt & Lock Lever Base Plate Mechanism Large 150x255mm

Amazon 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.

All 4 holes lined up with my chair holes perfectly, very easy to fit and install, 15mins and fitted! Rocking function is exactly what i expected 5 degrees is good gives with a decent amount of rocking travel to relax sitting in my game chair. - the friction/ resistance rocking control knob is easy to turn to the desired setting works well very easy. solid steel construction wont bend or distort. price is ok and what i would expect to pay for a solid steel well-made Plate Mechanism' would recommend.

BiMi 50137 Replacement Office Chair Tilt & Lock Lever Base Plate Mechanism, Fitted a Corsair T3 rush perfectly. The mechanism is pretty much the same as the one i took off minus a few smaller details. I had to repair a family members chair due to the fact the gas lift cylinder failing and part of the system split the metal so i had to remove the entire cylinder and lift mechanism. Assembly was easy and took a mere few minutes in order to screw the plate onto the chair. There is a slight tilt after the install its minor however, the chair does wobble very slightly. definitely worth the price when repairing a fairly expensive chair. Considering how much Corsair quoted this i felt was a better option and more affordable. Overall fitted perfectly, no modification needed, sturdy and it pretty seemed very similar to the one i took off. Only 4* due to the fact there is a minor wobble other than that its a good affordable option.

Bought this as a replacement for the tilt and lock lever base plate mechanism for my Cherry Tree office chair. Reason for replacing it was the gas lift had stopped working so I had to replace it with a new Tuka gas lift. However, while I could remove the bottom end of the old gas lift from the wheel base of the chair, the top end was firmly wedged into the base plate and simply would not come loose despite using plenty of WD40 and trying to knock it out with a hammer and rubber mallet. In the end, I decided to stop wasting my time and purchased this new base plate which fits into the bottom of my Cherry Tree office chair perfectly with all the screws lined up nicely. The Tuka gas lift also slots into place perfectly and I now have a chair which works great. Height and tilt work nicely and the chair is solid and sturdy. Been using it on my chair for 2 weeks now and have had no issues with it whatsoever. A great buy.

My old, and rather expensive, chair was on its last legs. It was hanging on like a loose tooth hangs, one sharp movement and it was going to be game over. So, balancing as carefully as I could I sat on it and did some research and found that my wobbly chair was most likely caused by the failure of this part. I bought it, got it next day, Saturday, thanks to prime. Put it to one side as it was going to be a job to do mid week. Well the chair had other ideas and upon seeing I had bought a new part it decided to fail in dramatic fashion dumping me and my heavy set figure on the floor. What Luck!, well not exactly the words I used at the time but still, I am glad it waited for the part to come. Super duper easy to fit. Get a hammer, because you are going to have to knock the old on off most likely. Just keep sliding the hammer up the pole, tapping the bush that is still on. Turn it as you go, oh, and make sure you are not aiming it at anything breakable because it will probably shoot off with a ping when it finally goes. Turn tap, turn tap, turn tap.... ping. Take the bolts out of the old one on the bottom of the seat. Shove this on in its place, making sure you have it the right way around or you will spend the rest of your computer time sitting like the Fonz (for the kids out there, this means backwards on your chair looking cool). Once it is bolted on, just put it over the pipe, push it down a bit and sit on it... congratulations, you have just fixed your chair... Mine was a £200 chair so as you can imagine I am extremely pleased... and proud too of the handy little job I have done. Good Luck, and remember to measure before buying. UPDATE... 11/12/15 --- Just over 12 Months and still hasn't dumped me on the floor yet. Just weighed myself and I am 18 stone, or 115kg for those modern folks, also keep in mind that I often fall asleep in my chair, reclined with my feet up on the desk so I am not exactly giving it an easy life. There is a little bit of a wobble now, but nothing serious. I reckon in about another year (2 yrs total) it will be time for another repair,,, unless I lose a few inches of flab in which case I might get longer out of it.

So like many others here I wanted to avoid buying a new chair. So brought this part and some wd40. The good news is after fitted, it feels so much better, even better than when the chair was new (new chair always had awkward forward tilt, this one is good angle). Word of warning though, removing the old part is super hard. My hammer actually broke, the end of it came off with the force I was putting into it, I kept pushing it back on and was about to give up, did some soft taps as I was losing the will to carry on and the soft taps suddenly it started moving off. After that was easy street although a little bit of trouble lining it up with the gas pipe again as on my own. Very happy with the purchase.

Fabulous item and really easy to fit. Saved me a fair bit in having to purchase a new chair. Well worth it.

From looking at other reviews and my experience now of this, it lasts about two years before the weld fails holding the receiving socket to the bracket. So it depends on what your goals are - it fits my chair fine, is easy to put together, and it lasts roughly this long before you need a new one.

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

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.

Ein Superersatzteil! Bei meinem etwas über 1 Jahr altem Chefsessel hatte sich die Grundplatte verabschiedet, indem sich die Ösen der Befestigung auflösten! Da die Polsterung und die Gasfeder des Bürostuhls aber noch prima in Schuss waren, suchte ich nach einer Reparaturlösung. Mit diesem Teil habe ich sie optimal gefunden! Wichtig waren die Lochabstände und der Durchmesser der Federaufnahme und diese passten genau. Der Austausch war nach wenigen Minuten geschehen: Vier Schrauben lösen, mit Gummihammer das defekte Teil abmachen. Bitte mit vorsichtigen Schlägen abwechselnd auf allen Seiten, um die Gasfeder nicht zu beschädigen! Das Ersatzteil an den Sitz geschraubt - die Löcher passten exakt - und auf die Gasfeder aufgesetzt. Fest verbunden wird der Stuhl dann durch das Gewicht beim Draufsetzen. Kein Quietschen oder Knarren mehr, die Wippmechanik funktioniert auch gut! Die 20 € für die Ersatzgrundplatte haben sich mehr als gelohnt!
