Total comfort and modern design

If you are looking for a chair that really takes care of your back, the Spring Breeze Series is an excellent choice. The lumbar support and the 3D headrest make the difference during long work or study hours. It is very fresh thanks to its breathable material, it feels robust and the executive design gives an elegant touch to any space.

Great chair keeps you feeling cool!

I love the mesh areas - it keeps you feeling cool. I love the high back and neck area (it’s adjustable) the seat tilts back and allows you to relax (for me it’s a good back stretch ) I recommend this chair for any office use!
