Why repair?
Repair instead
Repair instead
of replace.
Every year, millions of gaming and office chairs are thrown away because of a single worn part — a broken gas lift, a cracked seat, a faulty mechanism. In almost every case, the chair is otherwise perfectly usable.
Save up to 80% vs. buying new
A new gaming chair costs €200–500. A replacement gas lift costs €19–30. A new seat costs €80. Repairing is almost always the smarter financial decision.
Lower carbon footprint
Manufacturing a new chair produces approximately 60–80 kg of CO₂. Repairing one produces near zero. Choosing repair over replacement is one of the simplest sustainability decisions you can make.
Often better than original
Our replacement seats use 36 kg/m³ high-density foam — standard gaming chairs use 28 kg/m³. Our steel frames are reinforced. In many cases, our spare parts outlast the originals.
Under 30 minutes to fix
Most gaming chair repairs require no special tools. Every product comes with access to step-by-step video guides. Complete the repair yourself in under 30 minutes — even without technical experience.
Quick answers
Common questions.
How do I fix a sinking gaming chair?
A sinking gaming chair is almost always caused by a worn-out gas lift cylinder. The gas lift has lost internal pressure and can no longer hold your weight. The solution is to replace the gas lift — it takes 20–30 minutes, requires no special tools, and costs €19–30. See our step-by-step gas lift replacement guide.
What gaming chair spare parts do you sell?
We sell gas lifts (Class 3, Class 4, Heavy Duty), armrests (2D, 3D, 4D, 5D), tilt mechanisms (Butterfly, Frog, Multifunction), universal seats and backrests, chair wheels, bases and accessories including PU repair kits and pillow sets. All parts are compatible with approximately 95% of gaming chairs on the market.
Are your spare parts compatible with my gaming chair?
Our universal seats and backrests are designed to fit approximately 95% of gaming chairs. Gas lifts use standard Class 3 and Class 4 sizing that fits most chairs. All product pages list full compatibility details. If unsure, contact us with your chair model and we will confirm.
Are your replacement parts original OEM parts?
Our parts are not always identical to original OEM components — they are often improved versions. Our replacement seats use 36 kg/m³ high-density foam, while standard gaming chairs typically use 28 kg/m³. Our steel frames are reinforced for greater durability. In many cases, our spare parts outlast the original components that came with the chair.
Do I need technical skills to install the parts?
No. All spare parts come with access to step-by-step video guides, making installation easy even for users without technical experience. Most repairs take under 30 minutes with no special tools required.
Why repair a gaming chair instead of buying a new one?
Repairing is significantly cheaper. A new gaming chair costs €200–500, while a replacement gas lift costs €19–30 and a new seat costs €80. In most cases only one or two parts are worn, while the rest of the chair remains fully functional. Repairing also reduces CO₂ emissions — manufacturing a new chair produces approximately 60–80 kg of CO₂.
Do you ship gaming chair parts across Europe?
Yes. ChairRepair.eu ships spare parts to all EU countries and the UK. Most orders are dispatched within 1–2 business days from EU stock. Shipping costs and estimated delivery times are shown at checkout.
Are your gas lifts BIFMA-certified?
Yes. Our gas lifts are BIFMA-certified and tested under pressure loads of up to approximately 14,000 Newtons. This ensures durability and safety — especially important for gaming chairs under heavy dynamic use.
What warranty do you offer on gaming chair spare parts?
We offer a 3-year warranty on our universal gaming chair seats and backrests. Gas lifts and tilt mechanisms carry a 1-year warranty. If a part fails within the warranty period due to a manufacturing defect, we will replace it free of charge. Our BIFMA-certified gas lifts are additionally tested to 14,000 Newtons of pressure before shipping.
