Multiblock mechanism

This mechanism allows the user to sit in a freely swiveling position or to fix the desired angle of tilt in one of the selected positions. The chair can be equipped with 3, 4 or 5 locking positions. One of the most important features of the mechanism is that the seat and backrest are interconnected. When the backrest moves, the seat moves 1:1 in the same direction.

Chair Center experts advise that the multiblock office chair mechanism is suitable for people who like to swivel freely when sitting, or who like to change position frequently during the working day, as well as for people who like fixed seating.

The firmness of the chair’s oscillation can be adjusted individually according to the weight of the sitter. Office chair SONATA H 24/7 with pneumatic lift easily raises or lowers to the desired sitting height. Task chair SONATA H 24/7 with multi-block mechanism is recommended for longer sitting periods of 8 hours.

Arm support

The armrests of this chair provide support for the arms. This reduces tension on the arms, shoulders, neck and hand muscles. This is particularly important when sitting for long periods of time. When work is finished, the armrests can be used as a support when standing up, thus reducing the strain on the pelvic muscles.

It is recommended to choose an armrest position that allows the arms to be bent at about 90° while sitting at the desk, with the shoulder blades naturally relaxed and in a straight horizontal line. It is important to ensure that when sitting in a chair, the legs of the person should be at a straight 90° angle to the floor.

SONATA H 24/7 is an excellent ergonomic solution. If you have any questions about how to adjust your ergonomic chair, please read the advice from the Chair Centre or contact our consultants.

Adjustable headrest height

People who spend a lot of time working at a computer often eventually start to feel fatigue in their shoulder and neck muscles, leading to discomfort and muscle tension. SONATA H 24/7 headrest helps relieve some of the tension and pain by providing support for the neck and upper back.

The headrest can also improve your posture. When the head is unsupported, people automatically lean forward when working at a computer, creating pressure in the neck. Sitting in not optimal position for prolonged periods of time can lead to long-term spinal problems.

A headrest provides comfort, makes the user feel better and more productive while working, and increases the likelihood of maintaining the correct posture while sitting. The headrest is height-adjustable, so everyone can find the most comfortable seating position for their height. Before buying a chair with a headrest, we recommend to make sure that the Desk chair SONATA H 24/7 will provide the user with comfortable support and that seating experience will feel comfortable. We recommend visiting our showroom and trying this chair model in person.

Tapestry seat and backrest

This SONATA H 24/7 is covered with tapestry fabric. This type of fabric is particularly popular because it is soft and pleasant to the touch and comes in a wide range of colours. The tapestry chairs are very easy to match with the surrounding furniture and decor.

Tapestry is a relatively durable and long-lasting material, so the chair can be used comfortably for many years.

It is worth mentioning that chairs covered in mesh or tapestry  sometimes can become a favorite place for cats to scratch their claws. Therefore, before buying an office chair SONATA H 24/7, consider your pet’s taste as well.

The purpose of the standard is to ensure that the textile material does not contain any harmful chemicals or other substances. This is particularly important as our bodies interact with the fabrics of the chair on a daily basis and children come into contact with the fabrics. OEKO-TEX certification tests various parts of the production process, from the dyeing of the material to the hemming.

11 mm castors (for hard floors)

These wheels are softer and do not scratch hard flooring. If you prefer a stable sitting position on this Ergonomic chair SONATA H 24/7, you can also purchase optional feet instead of castors. When choosing chair castors, it is very important to pay attention to the type of use and the floor covering, if you are not sure we recommend you contact our consultants or visit our showroom.Learn more.

Our specialists recommends taking breaks during work based on medical research. Taking a 15-minute break every 45 minutes to move around. Prolonged sitting in one fixed position increases the likelihood of chronic pain and cardiovascular disease.

Chair feet

When you buy an office chair, we often get questions about whether the castors can be replaced with feet. Of course! An office chair with feet is stable and its functionality remains unchanged. This is especially true for workplaces where there is a small, limited working area and stability is needed: shops, warehouses and production companies. People with disabilities or elderly customers often ask for chairs with feet. Learn more.
