EN 1335 Office Chair Choices

Start With the Required Standard Reference

Include EN 1335 explicitly in the seating brief where it is a project requirement. Obtain the supporting information for the exact chair being assessed and retain it with the specification. A clear reference makes the requirement reviewable and gives facilities staff a consistent basis for assessing later changes.

Keep that documentation alongside the practical workstation assessment. The association with an office seating standard does not identify the chair’s precise adjustment ranges, armrest arrangement or upholstery. Those details still need to be established so the chosen configuration can be compared with the user’s task and the room’s furniture.

Compare Different Seating Forms by Activity

Ergonomic office chairs, executive chairs, stools and task chairs are represented in this selection. Start with the activity assigned to the seating position, then assess the relevant form at the intended desk or surface. The chair type alone does not determine whether its shape and functions suit the work.

Use a representative task to compare access to equipment, the seated position and the space around the workstation. Where seating will be shared, include users with different requirements. Ask them to set the chair themselves and explain any setting they cannot establish, rather than relying only on an initial impression.

Confirm the Adjustment Package in Detail

Seat height, seat depth and back height adjustment vary, as do lumbar support and headrests. Armrest choices include 4D armrests, fixed arrangements and options without armrests. Confirm each required feature and its measurements individually; the presence of one adjustment does not establish that another is included.

Manual height adjustment, synchronous mechanisms and configurations without a mechanism are represented. Establish what the controls do on the particular chair and test them during normal work. For armrests, assess both their relationship with the user and their clearance at the desk, including the actual movements provided where adjustment is offered.

Keep Other Requirements Separate and Traceable

Fabric, mesh, leather and PU leather provide upholstery choices, with beige, black, blue, brown, green, grey, orange and red among the colours. Review the exact finish and its care instructions. Environmental designations and fire performance references are represented, but their applicability should be confirmed independently for the selected configuration.

The stated maximum load is 135 kg, while warranty periods vary between two and five years. Record the applicable terms with the chair specification. Keeping the standard reference, user fit, materials and other project evidence together allows each requirement to be checked without assuming that one document answers every seating question.

Questions About EN 1335 Seating

Does EN 1335 mean every chair has identical features?

No. This selection includes different chair forms, mechanisms and support arrangements. Confirm the precise functions and measurements of the chair being considered, then assess them against the intended user and workstation.

Should an EN 1335 chair still be trialled?

Yes. A practical trial helps establish how the exact configuration works with the desk, task and user. Include adjustment operation, armrest clearance and representative activities in that assessment.

Are fire and environmental references included automatically?

Check them separately. Particular references are represented across this selection, but the evidence needed for the room should be confirmed for the exact chair and finish rather than inferred from EN 1335.
