Both chairs are ergonomic and offer all the necessary adjustments for a healthy sitting posture. They are both extremely comfortable, but their comfort differs.
We strongly recommend trying them in person. We cannot tell you that one chair is better than the other — both are among the most comfortable and ergonomic chairs on the market. However, if you have the opportunity to try them, you will likely find the chair that best suits your body shape.
That said, the Aeron chair stands out because it is available in three different sizes. It is the only chair on the market to offer this option (A = small / B = medium / C = large).
The Aeron chair in size B, with all options, is comparable to the Mirra 2 chair with all options in terms of comfort and ergonomics.
The lumbar support on the Mirra 2 is different (it moves up and down).
Overall, both chairs are excellent ergonomic chairs. The difference lies mainly in the feeling they provide when seated.
The Cosm chair was designed for shared workspaces where chairs are used by multiple people. It is not part of the ergonomic task chairs we typically recommend for full-day desk work.
However, the version with adjustable armrests can be suitable for some users. If you are considering it as a task chair, we strongly recommend trying it first to see if it meets your comfort and support needs.
We do not have set opening hours (despite what is listed on Google), as our showroom is by appointment only. You can either send us an email or call us to arrange a visit.
Unfortunately, we are not open on Saturdays.
However, we do our best to be as flexible as possible during the week to welcome you by appointment.
