“The MasterSeat is an excellent office chair for the home office and workplace! It can be individually adjusted to your own needs.”

Kevin Krüger - Office Chair Expert

Height-adjustable backrest with integrated lumbar support

The backrest of the MasterSeat can be flexibly adjusted in height - so that the lumbar support sits exactly where it should. This relieves your lower back, reduces tension, and keeps your posture stable - no matter how tall you are.

4D chrome armrests

The 4D armrests can be individually adjusted so that your shoulders and arms remain relaxed at all times. Perfect for anyone who types a lot or switches between mouse & keyboard.

QuantumFlex mesh for back & seat surface

The breathable high-tech fabric ensures maximum air circulation, adapts flexibly to your body, and prevents heat buildup - for a pleasantly cool sitting experience, even on long days or in summer temperatures.

Individually adjustable seat depth with seat slider

With the integrated seat slider, you can adjust the seat depth to your body proportions in seconds. This improves blood circulation in the thighs and ensures ergonomic seating at the highest level.

Who is the MasterSeat best suited for?

For everyone who works many hours daily sitting with concentration - in the office or at home office

For people with back problems who want a long-term improvement

For tall or short people who need a chair that truly adapts to their body

For freelancers & entrepreneurs who do not want to compromise on ergonomics and quality

For companies that want to offer their employees premium comfort, productivity, and health in the workplace

Absolute top class

"I have tried several office chairs, but the MasterSeat plays in a league of its own. Backrest, armrests, seat depth – everything can be perfectly adjusted. Since I have been using it, I no longer feel any pressure in my back, and my workdays feel noticeably more relaxed."

 

Thomas K.

My back thanks me

“I sit at the computer 9–10 hours every day. With my old chair, I constantly had tension in my neck and back. The MasterSeat is the first investment that truly made a difference. No more pain – instead, more energy in the evening. Every penny is worth it.”

 

Anna M.

Assembly in 10 minutes, comfort for years

"Delivered, unpacked, assembled – in less than 5 minutes it was ready in the office. You can feel the quality immediately, everything feels sturdy and well-made. Especially the 3D headrest is a dream. For me, the best chair I have ever had."

For a break quality like you have never experienced before.

Productivity through the roof

"I never thought a chair could make such a difference. But since I have the MasterSeat, I sit much more focused and no longer get tired so quickly. My to-do list during the day is suddenly much shorter. Simply brilliant!"

Sarah L.

Perfect for working from home

“I work full-time from home and searched a long time for a chair that doesn’t drive me crazy after 2 hours. The MasterSeat is very comfortable, breathable, and flexibly adjustable. Especially the mesh material is worth its weight in gold in summer. Never sweat at the desk again!”

 

David P.

The difference lies in the details

"You notice it as soon as you sit down: This is no ordinary office chair. The MasterSeat feels as if it was made for me. Everything is adjustable, the casters glide quietly over my hardwood floor, and the design fits perfectly in my office. I feel like I am sitting on the very best."

The science behind the MasterSeat

Your body was made for movement - not for sitting still for hours.


But that is exactly what we do every day: 8 hours at the desk, 2 hours in the car, 3 hours on the couch.


The problem?

 

Muscles and spinal discs suffer from the stiff posture and lack of relief.

The MasterSeat was developed precisely for this purpose.

Based on the latest findings from ergonomics, orthopedics, and movement sciences, it supports your body where it is most stressed while sitting:

The lumbar spine, which bears enormous pressure with poor posture

The back muscles that weaken during static sitting

The intervertebral discs, which rely on movement to be supplied

The neck, which is often overstrained during classic screen work

The MasterSeat brings all of that into harmony:

The MasterSeat provides noticeable relief for the lower back, supports your neck in every posture, encourages small movements while sitting, and eases pressure on your spinal discs—all without you having to adjust or fine-tune anything.

 

With its adjustable backrest, 3D headrest, breathable QuantumFlex padding, and 135° recline function, it combines the best of modern body-friendly design in a single chair.

 

The result:


You sit more actively, with less strain and in better health—without having to think about it consciously. And common issues like back pain, stiffness, or tiredness at the desk are sustainably reduced.

 

Sounds good?
