How to choose between the Active models
Use the features you will notice during a normal workday to narrow the range. If you prefer to work without armrests, compare the 12900 and 12930. The 12900 is listed with a permanent-contact mechanism and adjustable seat and back height; the 12930 has a synchronous mechanism and a sliding seat for depth adjustment. This makes the seat adjustment a useful point of comparison between the two armless options.
If you want armrests, decide whether fixed or adjustable support is a better fit for your desk and working position. The 12907 has armrests and a synchronous mechanism, while the 12927 is specified with fixed armrests. For more adjustment at the arms, the 12905, 12925 and 12935 are listed with 3D-adjustable armrests. Check the individual listing for the complete configuration rather than assuming every feature is shared across these models.
When a sliding seat may suit you
Seat-depth adjustment can be a deciding feature if you want to alter how the seat meets your legs. The 12930, 12935 and 12937 are listed with sliding seats. Compare those options by armrest type and mechanism: the 12930 is armless, the 12935 has 3D-adjustable armrests, and the 12937 has fixed armrests. The 12930 and 12937 are also listed with synchronous mechanisms; consult each product page for its full adjustment details.
Check upholstery and configuration details
Active chairs are upholstered, but fabric information is not identical across the family. Serie 200 and category B upholstery appear in the details for selected models, including the 12920 and 12930. The 12925 is listed with Serie 200 240 upholstery. The collection also lists colors such as black, blue, grey, green, red and white, among others. Availability can differ by chair, so verify the finish choices on the model you are considering.
Before choosing, compare the exact adjustment functions, armrest style and mechanism on each listing. Also confirm the upholstery category and color, and consider whether your desk setup allows the armrests to fit comfortably. If you are selecting chairs for a team, identify the features that need to be consistent and where individual preferences can vary.
Review the options before you decide
Look at the product details for the models that meet your requirements and compare them side by side. This is especially useful when two chairs share a general feature, such as armrests, but differ in whether those armrests are fixed or 3D adjustable, or when one model adds seat-depth adjustment. Myntwork offers Leyform Active chairs on a monthly lease; check the individual product pages for the available configurations and leasing details.
