The unique design and mechanical structure of the zero-wall sofa allow the backrest to either tightly touch the wall or maintain only a minimal distance when fully reclined or lying down, significantly saving space.

The key design feature is the automatic forward movement of the seat and backrest. When the user activates the recline or lying function, the seat moves forward, while the backrest tilts backward. This motion ensures that even when the sofa is placed against a wall, the backrest will not touch the wall during the reclining process.

This design is especially practical for small living rooms or for users who want to maximize space utilization.

This sofa design is inspired by the weightless experience of astronauts in space. Its goal is to create a seating position that simulates a weightless environment, helping to reduce physical pressure, improve blood circulation, and enhance comfort.

By adjusting to specific angles, the sofa allows the user's legs to be raised to roughly the same level as the heart or slightly higher when sitting. This position is known as the "zero-gravity position." When the chair is fully reclined, the angle between the legs and torso is approximately 128°.

This design is intended to distribute body weight evenly, reducing the pressure on the spine and joints.
