# Chair Mount Compatibility

These chairs / brands have been confirmed as (in)compatible.

However, it is good practice to double-check whether your chair is indeed compatible:  
Aside from unlisted product updates, there can be outliers within a brand’s line-up.

You can use the Form template PDFs to do so; either via measuring, or by printing them at 100%.  
These can also be found on the related product pages.


### Rules of thumb for compatibility

* Mounting points underneath the seat pan are required.
  * For chairs with Side mounted armrests, as found on the IKEA Markus, check whether the Universal Basis + Form 1 is a fit.
  * Mounting options with 2 bolts are doable, 3-4 is preferred.
* Most ‘Gaming’ chairs with bottom-mounted armrests are compatible with Form 1 or 2.
* Chairs with proprietary design elements, like alternative armrest assemblies and ‘streamlined’ seat pans, are often incompatible.
* Most compatible chairs use Metric hardware.
  * In case your unit uses Imperial, relevant hardware has to be sourced locally.

If you're not sure, feel free to send us a message, and we will have a look.

Should you know of an (in)compatible chair that isn't listed, do let us know and we'll update the applicable list.


### Special note ( \*[] ) 

In certain cases, a chair is technically compatible, albeit with limitations to be aware of.   
Examples of this include, but are not limited to: 

* The chair is compatible with the centre mount bracket, and the side mounts.   
  However, for both to be used at the same time, you have to puzzle and stack.
* Certain control elements occupy the same space as the Form plate, and require remounting or removal.
* Special care has to be taken with the bolts, as the chair has capped inserts for the threads/limited room due to frame elements.


Were possible, we add the related note between the square brackets.
