Grammer MSG87 Mechanical Suspension Seat
Heavy-Duty Suspension Built for Big Operators

The Grammer MSG87 is a rugged, mechanical suspension seat built to handle extreme conditions and larger operators without compromising comfort or durability. Rated for occupants up to 180 kg, it features full mechanical weight adjustment and a robust scissor-style suspension system that delivers 180 mm of suspension travel—perfect for absorbing shock in rough environments like construction, mining, and forestry.

Its extra-wide seat base (up to 550 mm) provides a stable and comfortable platform, while optional side-to-side and fore-aft isolators reduce vibration and fatigue. With height adjustment up to 80 mm, tilt, lumbar support, slide rails, and more, the MSG87 allows for precise, ergonomic setup tailored to the operator.

This seat is often preferred over air suspension options where mechanical simplicity and toughness are more important than fine-tuned air comfort. Industry dealers regularly describe the MSG87 as a top-tier mechanical suspension and a workhorse for high-weight users.
