An ergonomic office chair with multiple adjustment points can make a world of difference for anyone sitting through long work sessions. However, the real value of these features comes down to how seamlessly the seat, backrest, lumbar support, and armrests work together to support a healthy posture.
The InterGlide X5 is a highly adjustable ergonomic chair that combines firm, breathable mesh with a sliding seat, height-adjustable backrest, QuadFlex lumbar support, 6D armrests, and a flexible headrest. Its sturdy build, smooth controls, 160-degree lockable recline, and adjustable leg rest make it well suited to long work sessions and short breaks, although its firm feel and exposed mechanical design may not suit users seeking softer cushioning or a more understated chair.
Pros
- Extensive adjustment across the seat, backrest, lumbar support, headrest and armrests
- Firm, breathable mesh provides structured support without trapping heat
- Smooth, accessible controls with a stable 160-degree recline and adjustable leg rest
Cons
- Firm mesh may feel less comfortable to users who prefer softer cushioning
Separate controls make it easy to adjust a chair for different body sizes, desk heights, and working habits. Most modern chairs are easy to set up, but getting the best comfort and support still depends on how carefully each part is adjusted to fit the user.
The InterGlide X5 enters the market with a strong focus on personal customisation. With parts that can be adjusted separately, firm mesh upholstery, and a wide recline range, the chair is designed to adapt smoothly to individual sitting preferences throughout the workday.
Industrial styling with breathable mesh
The X5 has the look of a premium mesh office chair. Instead of hiding its moving parts inside a padded frame, the backrest keeps its lower-back support, adjustment rails, and control levers clearly visible. Available in black or grey, these exposed parts give the chair a practical appearance that suits a dedicated workspace better than a cosy living room. A strong polyamide frame, aluminium wheelbase, and polyurethane wheels give the chair a solid and sturdy build.
That solid build also translates directly to stability in daily use. At 24 kg, it stays firmly in place during focused work and when fully reclined, while supporting up to 150 kg. Despite its weight, the smooth polyurethane wheels allow it to move easily across different floor surfaces and between rooms. The chair offers many adjustment options, but its design looks more practical than sleek or simple. Its physical footprint also expands significantly when reclined, requiring ample clearance both in front of and behind the chair to accommodate the backrest and leg rest.
Italian mesh covers both the seat and backrest, offering a firm, structured platform rather than soft cushioning. Stretched tightly across the frame, the material holds the body in place rather than allowing it to sink into thick cushions like typical office chairs. This design improves airflow around the back, hips, and thighs, which is especially useful in Singapore’s warm and humid weather. As the seat is firmer than traditional foam, users moving from soft, heavily padded chairs may initially feel more pressure or support around the thighs and lower back.
The divided backrest further creates an articulated shape that clearly highlights the individual support zones. While the exposed frame makes the chair look slightly larger, it also helps users understand how each part works when making adjustments.
Modular controls for tailored posture
The X5 functions as an integrated system rather than a collection of separate features. Adjusting one component changes how the rest of the chair meets the body, so overall comfort comes down to how well the different parts work together. Accessing these controls during daily work is straightforward, as the levers are clearly marked, easy to reach while seated, and simple to distinguish by touch without looking down.
At the foundation, the seat base provides up to 20 cm of height adjustment alongside 5 cm of sliding depth. Its gas lift (Class 4 hydraulic) piston raises and lowers smoothly, allowing for small height tweaks without sudden movement. The sliding seat depth is central to how the chair supports the thighs and aligns the spine with the backrest. Shorter users can pull the seat back to avoid pressure behind the knees, while taller users benefit from the extra length. Correct seat alignment keeps the lower back resting firmly against the frame, providing the baseline for proper posture.
Above the base, the backrest provides 12 height positions across a total range of 48 mm, altering where the upper and lower sections meet the spine to suit different torso lengths. Positioned directly below it, the QuadFlex lumbar system offers four dedicated height and depth settings. Pushing the support forwards applies firm pressure against the lower spine, while shifting it backwards creates a gentler feel.
Higher up, the headrest moves vertically, tilts, and turns, offering 16 height steps alongside a 45-degree turning range. InterGlide states that it is built to support individuals from 120 cm to over two metres tall. While testing did not cover that entire spectrum, the mechanism provided more than enough movement for a 175 cm user, supporting different head and neck positions during both upright work and full recline.
The padded 6D armrests also move forwards, backwards, upwards, and downwards, and feature width adjustments to bring them closer to or further from the torso. They can even flip and rotate through a full 360 degrees, easily matching different desk heights, keyboard placements, and typing styles. Their padded surfaces feel noticeably softer than the firm mesh seat, offering welcome pressure relief for the elbows throughout the day.
When it is time to step back from work, the backrest can recline and lock at angles up to 160 degrees. InterGlide markets this feature as its “Antigravity Recline”. Completing the setup, a built-in adaptive leg rest extends up to 45 cm from beneath the seat base, allowing the chair to transition smoothly from an upright working tool into a comfortable seat to relax during breaks.
The verdict: InterGlide X5
The InterGlide X5 is built for users who want to shape a chair around their body rather than adapt to a fixed seating position. Its sliding seat base, height-adjustable backrest, customisable lumbar support, multi-directional armrests, and flexible headrest offer an impressive level of physical control. Meanwhile, the lockable 160-degree recline, five tension levels, and adaptive leg rest with a stated adjustable length of 45 cm extend its usefulness beyond standard desk tasks.
Because each component adjusts independently, dialling in the chair to match your desk height and preferred posture is quick and straightforward. This creates a versatile setup that transitions smoothly from hours of focused typing to a comfortable space for resting during breaks.
At its promotional price of S$569, the InterGlide X5 brings firm, breathable mesh and extensive ergonomic adjustment below the S$600 mark. Its broad range of controls, 160-degree recline and integrated leg rest make it a practical option for a dedicated workspace, although buyers should note that this price may change after the promotion ends.
