OM5 Series

The OM5 Series® is the peak of ergonomic office chair design. Designed by award winning designer Francisco Romero, the OM5 combines chic style and revolutionary ergonomic technology.

The OM5 features a self weighing mechanism which allows the chair to intuitively respond to the user's natural movements without the need for constant manual adjustments.

OM Seating's OM5 Series® was designed with elegant simplicity in mind.

In 2015 PC Gamer Magazine rated the OM5 as the best PC gaming chair on the market: Recommended PC Gaming Chairs on PCGamer.com

The OM5 was positively reviewed by Linus Tech Tips, who loved the simple adjustments and intuitive motion-activated lean.

How it Works

There is no tension knob or traditional back angle lock necessary. The specifically calibrated geometry of the OM5 does the work of balancing your body's weight throughout the chair's recline.

Simply lean back using your hips, and rest your back at any position without the need for a locking paddle. And when you want to move again, just move.

“My skepticism didn’t last long, though, because when it comes to the OM5, sitting is believing. ”

— Tim Clark (PC Gamer Magazine)

Viewing angle shifts only slightly when reclined, promoting natural movement and comfortable working in a variety of postures.

Arm pad slides forward while in recline, but does not interfere with the desk.

The seat slides forward while the upper body leans back, keeping you close to your work even when you recline.

True Ergonomic Design

This award winning chair features a revolutionary self weighing mechanism that consists of 5 roller wheels. These wheels distribute the user's weight evenly throughout the entire reclining motion, allowing for an non locking design.

Traditional ergonomic office chairs have between 3-6 adjustments, while the OM5 requires only one. This simplified design ensures the user is in an ergonomically optimal seating position at all times.
