Are COSM Chairs Comfortable?

Yes, they are!

Americans spend over half of their day sitting. If you’re an office worker, you probably spend over 15 hours a day sitting.

An uncomfortable chair can lead to stress, pain, and other health issues. So if you are planning your office space or redesigning it, one of your top priorities would be to find a chair that offers you comfort, adjustability, and support.

COSM chairs are comfortable, self-adjusting, ergonomic, and offer great back support. These durable chairs offer adjustable armrests, footrests, and seat height features to suit people of all shapes and sizes.

With a 12-year warranty scheme and easy return policies, the COSM chair is a risk-free, excellent investment and addition to your office space. The COSM chair is one of Herman Miller’s most expensive offerings, so it ensures that it meets your requirements before you buy it.

This comprehensive guide covers everything you need to know about the revolutionary COSM chair — if it is comfortable, worth the penny, and the most effective way to put it to use.

What are COSM Chairs?

Meet Cosm: The Self-Adjusting Office Chair

Cosm Chairs are self-adjusting chairs that Herman Miller designed in collaboration with Studio 7.5, a German brand that believes in delivering excellence in furniture.

Herman Miller is an established office furniture brand that was founded in 1923. They occasionally offer new, state-of-the-art furniture.

They released the COSM chairs in 2019. These chairs offer excellent quality design, comfort, and style.

The COSM chairs are made in the United States of America and sold all over the world. People love them for their high-end design and incredible back support.

COSM chairs come in these dimensions — width: 746 mm, depth: 680 mm, height: 1145-1310 mm, and seat height: 375-545 mm.

The best feature of the chair is the high back that supports all body shapes very comfortably. The graphite mesh and carpet clusters ensure that the chair lasts a long time without wearing out.

The COSM chairs are available in three arm options, three varying back height options, five finish options, six exciting color options, and a couple of different configurations.

One downside to COSM chairs is the price of the chair. It is one of the most expensive releases by Herman Miller, so unless you have an extensive budget, this chair can be pretty steep.

Yes, COSM chairs are comfortable. COSM chairs are incredibly comfortable with their attention to ergonomics, support, and adjustability.

The manufacturers of the chair spared no effort to make the chair a customer favorite. These chairs are the epitome of comfort, style, and class.

Unlike any standard chair on the market, the COSM chair comes with a first suspension armrest. This helps you keep your hands in a relaxed position without putting too much strain on them.

Another feature of the chair is its fantastic ergonomics. The chair’s intercept suspension and back support are designed to cater to all body shapes and conform to all sizes. You get ample uninterrupted support from the chair while ensuring that your back remains straight and your posture is perfect.

The suspension is designed in an hourglass shape that is attached to the chair’s frame. This creates high and low tension areas in the chair so that it comfortably supports your body without exerting too much stress or pressure on it.

Are COSM Chairs Worth it?

The chairs come with an impressive 12-year warranty plan and easy return policies. So even if you are unhappy with the purchase or the chair has sustained damage, you can always get it repaired free of cost.
