Leaf office chair

The Leaf owes its shape to the lines and veins of a leaf. The back system adapts to your posture and the seat has extra thick foam. The back comes in mesh or, in the leaf-shaped version, fully upholstered.

Back

• Mesh: mesh, with an upholstered seat in eleven fabric groups
• Leaf-shaped upholstered: back and seat in the same fabric, in BN Bondai or AB Xtreme Plus

Armrests

• Without armrests
• 2D armrests in black with a PU top
• 4D armrests in black with a pivoting and sliding PU top
• 4D armrests in white-grey with a black PU top
• 4D armrests with chrome support

Upholstery

The fabric group determines the price. Within a group every colour costs the same. You choose the colour after ordering; we will contact you about this. All colours per fabric group are shown with the photos, and the complete fabric chart can be downloaded: fabric chart (pdf).

The leaf-shaped version is fully upholstered and is therefore only available in BN Bondai or AB Xtreme Plus.

What does the Martindale figure mean?

In the Martindale test a fabric sample is rubbed back and forth under a weight until wear appears. The figure is the number of rubs the fabric achieves. Below 25,000 is light domestic use, 25,000 to 40,000 normal office use, above 40,000 intensive office use and above 100,000 suitable for 24-hour use such as control rooms and shift work. A higher figure says something about wear resistance, not about how the fabric feels.

Differences between the materials

• Polyester (AL, BN, AB, ME, CH, ST) is strong, colourfast and easy to maintain. AB and CH are made from recycled yarn.
• Wool blends (CS, SY, RM) feel fuller and are less prone to pilling. They are somewhat more sensitive to stains.
• Mesh (RR, RY) is a tensioned mesh. It breathes best and gives way.

All fabrics and mesh comply with EN 1021-1 and EN 1021-2, the European standard for the fire behaviour of furniture upholstery. AL, BN, AB, ME, CH, ST, CS and SY carry Oeko-Tex; AB, CH, ST, CS, SY and RM are EU Ecolabel certified.
