Ergonomic Seating

Have you ever wondered why you can sit in an Eames chair for hours without back pain, but a generic office chair leaves you stiff after 30 minutes? The answer lies in Passive Ergonomics.

The 15-Degree Tilt

Most iconic lounge chairs are designed with a slight backward tilt. This shifts the weight from the base of your spine to the back of the chair, instantly relieving pressure.

Shock Mounts

The Eames Lounge Chair was groundbreaking for its use of rubber “shock mounts.” These allow the chair to flex with your movements, absorbing energy like a car’s suspension.

High-Density Support

Cheap chairs use low-density foam that collapses over time. Masterpieces use multi-layered high-density foam that provides different levels of support as you sink in, ensuring the “cradle” effect remains consistent for decades.

Furniture isn’t just art; it’s the science of relaxation.
