Sofa Gas Spring
Since 2002, Xingtai Juxiang Machinery Manufacturing Factory has focused on producing gas springs. Our Sofa Gas Spring is made for tatami structural frames, flip-top storage furniture, and practical couches. It operates steadily at temperatures between -40°C and +80°C and has a force range of 300N to 1500N and stroke lengths of 30mm to 500mm. With chrome-plated piston rods, dependable sealing structures, and integrated dampening systems, the product provides quiet, steady motion for both mass furniture manufacturing and custom furniture creation projects.
A sofa gas springs are hydropneumatic parts that use hydraulic oil for end-stroke dampening and high-pressure nitrogen to produce lifting power. It resolves two typical issues with furniture assembly: the need for a large amount of physical lifting effort for furniture frames and the sound of a harsh hit when backrests or lids close. In contrast to conventional coil springs, it offers consistent linear force during the whole stretching process, making recliners, storage ottomans, and adjustable furniture headrests easy to use.
This product line was created to meet the real production and application requirements of furniture producers:In order to safeguard furniture structures and guaranty safe use, an integrated damping buffer absorbs kinetic energy at the conclusion of strokes, preventing rebound and abrupt falling.
After tens of thousands of opening and shutting cycles, the optimized sealing structure successfully prevents oil and gas leakage that results in gradual force reduction by maintaining stable internal nitrogen pressure.
While seamless steel tubes offer steady structural support for extended usage, chrome-plated piston rods in various specifications lower friction and withstand corrosion.
Accurate structural alignment guaranties quiet operation without grinding or unusual sounds while in motion.
Convenient installation and direct replacement are supported by compatibility with popular mounting attachments such as ball joints, eyes, and clevises.

Sofa gas springs adapt to multiple types of functional furniture with different usage requirements. Functional recliners and electric sofas adopt these springs to coordinate backrest and footrest movement, with matched force values to fit frame weight and pivot distance, suitable for high-frequency cyclic use. Ottoman storage beds and flip-lid sofas normally use medium and high-force specifications to keep lids fully open without sliding, facilitating daily storage access.
Compact small-diameter models apply to adjustable furniture headrests, realizing stepless positioning and noise-free adjustment. Low-profile tube structures also fit narrow installation spaces of tatami lifting frames, no need for structural modification of furniture.

Every Sofa Gas Spring batch goes through a structured testing protocol before shipment. Cycle life testing verifies force fluctuation is controlled within ±5% after repeated use. Temperature resistance testing confirms stable lifting performance in high and low temperature environments, compensating for natural pressure changes of nitrogen gas in different seasons. Every single product passes airtightness detection to eliminate leakage issues. Stroke speed testing is also conducted to avoid excessive opening speed and prevent structural damage to furniture hinges.

We support full OEM and ODM customization with a 50-piece MOQ. Customers can adjust stroke length, force value, pipe diameter, rod diameter and end fittings according to furniture design demands. Our team provides professional force calculation support for new product development based on frame weight and structural parameters.
The factory supports small trial orders and bulk stable supply, with complete export documents and mature sales channels covering Europe, South America, the Middle East, Southeast Asia and other global markets.

Q1: Why do low temperatures make gas springs feel weaker?
A: Low temperatures cause internal nitrogen pressure to diminish, with lifting force decreasing by roughly 3% for every 10°C reduction in temperature. To ensure usable performance during seasonal temperature fluctuations, our products are tested across the whole temperature range.
Q2: Is it possible to fix broken gas springs?
A: These are pressure-bearing components that are completely sealed. The entire spring must be replaced rather than fixed if the seal breaks and pressure escapes.
Q3: How can the correct force value for furniture be verified?
A: Determine torque using the weight of the furniture frame and the mounting pivot distance. Our staff will suggest matching specs if you supply equipment designs and dimensional details.
Q4: What are the typical sofa gas spring end fittings?
A: Clevises, eyeballs, and ball joints are all accessible. The most popular joints for furniture are ball joints because they can adjust to small angular deviations while in use.
Q5: What distinguishes QPQ-treated piston rods from chrome-plated ones?
A: Chrome plating satisfies standard requirements for low friction and anti-corrosion. Better resistance to salt spray is provided by QPQ treatment, making it perfect for humid and coastal market conditions.
