Our happy customers have their say

I was looking for a Herman Miller Mirra for a long time as I mostly work behind my desk for half of the day. These chairs are kind of pricy but I could find a great model with a suitable cost by help of LoyalBrand. I bought Mirra business model with full warranty which helps me work more comfortably. LoyalBrand provided very friendly and personal service with a super fast delivery.

TL:DR: Negative experience, and clearly there are communication issues. The owner seems to be packed with orders due to COVID-19 (as he claims), and because business is blooming, he doesn't find it necessary to reply to emails or deliver a chair as promised, after it was ordered on his website.Me and my wife went to pick up a chair. The owner have accepted us really nicely, gave us an overview and was patient. From this point, I have asked the owner whether it's possible to have a trial chair delivered by a certain date. He agreed, and asked me to note this down in the comments section. I have selected a chair to try-out and ordered it via the website. Since this was not availble in stock, I emailed him and never got a reply back. After 8 days, I asked if there are any updates, and he offered two other type of chairs to rent for the same date. I also asked him to let me know if there are any changes. Needless to say he never showed up with any of these chairs, or called me. After a few days, I tried to reach out again, and he didn't bother replying back.Even though I have back problems and really need a comfortable chair, I have decided to cancel the order, and I would definitely recommend buying Herman Miller chairs elsewhere, preferably from someone who respects their customers.

I am very happy with the Herman Miller product and the service from LoyalBrand. Heerco has been extremely helpful and diligent throughout the whole process - choosing a chair model, delivering it and explaining all the adjustments.I've experienced the "only satisfied when you are" promise in practice. The first chair model that I picked didn't quite fit my needs after initial try out at home, and with no problems I was able to "upgrade" to another one.LoyalBrand provides the kind of service that made me feel comfortable with buying such a "high end" piece of furniture, so to anyone in doubt - I highly recommend them. After a few days in a chair that was good for me I had no doubts left whatsoever on the value I get for the money and how much better my "work from home" life has now become :).

For office chair we always knew that Herman Miller was the best especially for the type of work that we do and sitting for such a long time. We wanted to replace our office chairs and my husband came across LoyalBrand website. So we ordered 2 Aeron chairs and we are absolutely happy with it! They are such comfortable and ergonomic chairs, it sits well, just amazing! On top of that the service that Herco offers is outstanding, something you wouldn't get very easily in the Netherlands. He personally comes and delivers the chairs and make sure you are sitting on it properly and adjust it well so we are sitting in a proper ergonomic way. I am pretty sure if it were another company it would just be delivered and we would have to figure it all out by ourselves. Top Top Service. Will definitely be ordering more stuffs from LoyalBrand in the future.

Look no further for your perfect office / home-office chair. Top-notch service and product!Heerco is very pleasant and knowledgeable. Besides the best in market office chair you will get a crash course in the office ergonomics.

In search for a proper chair (Herman Miller Aeron) I found LoyalBrand. They have a very clear website, and nice differentiation to select the Aeron for you (Economy, Business, Luxury). The order process is clear and fast and Heerco delivered the chair personally after a few days at my home (home office). During delivery he explained how the chair works, where all the levers are located and the best way to set it up.Personal touch and fast delivery. LoyalBrand is your one-stop shop for anything Herman Miller.

I ordered a chair from LoyalBrand and I am absolutely pleased with my choice and how I was treated. The chair is great and also are the services. They deliver in person, which is nice and handy. I’ve got a loan chair the next day after I placed an order, such that I could already enjoy comfort while awaiting on my order to be delivered by manufacturer. The service is very friendly with good communication. I did internet research upfront and observed that also the prices are lower than those of competitors. Very happy.

I ordered a Herman Miller Aeron chair a while ago and everything went splendid. The service was superb, the chair is amazing and the pricing is fantastic!Do not hesitate to contact them if you're looking for a Herman Miller chair. They'll gladly explain everything to you and even have a home-service where they come to you!I could not be happier with this purchase.Thank you so much.

Excellent service. I bought a Harman Miller chair which didn't turn out to be a a perfect fit for me. I was able to swap this model for another one, which fitted better. Furthermore, the salesman knows fine details about the ergonomics and the production processes of the various models.

The whole process from ordering all the way to delivery couldn't have been a more pleasant experience. I'm extremely happy with my new Embody Chair and would definitely recommend people to get Herman Miller from LoyalBrand Network. Thank you!

I'm really, REALLY happy with this chair (Mirra 2), I think it's fantastic. Also I'm so glad about the advice you gave me during the delivery day, because having a great chair but then not being able to know what posture is good and what's bad doesn't help.I wish somebody at work would have advised me about not having the lower part of my wrist to the corner of the table! (they give us general clues but not that one, and I think I have got something in my fingers because of that... let's hope it goes away)

I had overall very good experience. After submitting my order via the web-shop, it was followed up quickly and accurately. Upon delivery I was pleasantly surprised by the detailed explanation of all functions available in my new chair, as well as its optimal configuration for my specific work place. Professional and to the point. Thanks! :)

My experience with LoyalBrand was outstanding. I can strongly recommend them if you want a high quality experience and delivery. I waited a long time to get my customized chair but it was worth it :) Would definitely order again if I need to!

Instantly comfortable, wherever, whenever.

Take a seat in the new Cosm and you’re likely to forget you’re even sitting in a chair at all. Next gen ergonomic design sets a new standard for instant, personalized comfort, regardless of how long you’re using it, what you’re using it for or who’s been in it before. The Berlin based Studio 7.5 designers knew that, like with the Mirra, Setu and Mirra 2 predecessors, the ideal chair should instantly provide a feeling of natural balance. The Cosm’s Auto-Harmonic Tilt instantly and automatically provides balanced support and movement, depending on your body and posture, to give a feeling of weightlessness. The Cosm is available with three different back heights and as a stool version to provide a new level of comfort, regardless of what environment you’re working in.

The Cosm’s movement mechanism is like the transmission of a car. There are manual and – in the case of the Cosm – automatic transmissions. With other self regulating models it’s the chair that decides how you should sit by forcing the body to follow its
movement mechanism. The Cosm’s Auto-Harmonic tilt adjusts to its user, regardless of his or her working posture, to offer a balanced reclining motion and personalized comfort. Studio 7.5 and Herman Miller have perfected the automatic movement mechanism by
developing a complex and finely tuned mechanism that makes all the difference in the world.

A completely new chair with a positive health impact and little to no impact on the environment.

To offer as much comfort and ease as possible, Studio 7.5 created Cosm’s Leaf Arms, which feature a soft but firm cradle design that provides a large, cozy resting place for your elbows. The sling based design makes it natural and comfortable to hold a book or a phone. The way the arm rests are angled means they don’t interfere with the desk when it’s time to go back online.
