Where Lambda chairs can work
The two models give buyers a choice between visitor seating and task seating without moving outside the Lambda family. Consider the LA 4001.15 for spaces where people sit for visits or meetings and a fixed-height, unupholstered chair meets the brief. Its swivel format and lack of upholstery make it distinct from the upholstered option in the collection.
The LA 4002.151 may suit a workstation or shared task area where castors, armrests and an upholstered seat are useful features to have. It has an Era fabric seat and a plastic base. The collection facts do not specify a particular work duration or ergonomic adjustment range, so assess the chair against your users’ needs rather than assuming it provides adjustable support.
How to choose between the two models
Start with the seating role
First decide whether the chair is mainly for visitors or for task use. Then compare the features that distinguish these options: upholstery, armrests and castors. The LA 4001.15 is the visitor chair and has no upholstery; the LA 4002.151 is the task chair with an upholstered Era fabric seat, armrests and castors. Neither model offers adjustable seat height, adjustable back height or adjustable seat depth.
Check finish and practical requirements
Color choices listed for the family include beige, black, blue, green, grey, red, brown, gold, pink, purple and silver for upholstery, and several colors for bases. These are collection-level attributes, not a guarantee that every color is offered on both chairs. Confirm the precise fabric, color and base combination for the model you are considering. The stated maximum load is 135 kg, and the listed warranty is two years.
Review specifications before ordering
GREENGUARD Gold is listed among the collection’s certifications. Fire-resistance attributes also include standards such as BS 5852 Crib 5, BS 7176, CAL TB117-2013, EN 1021-1 and EN 1021-2. Do not assume every model or upholstery option meets every listed standard: check the relevant specification for your selected chair and fabric if your project has compliance requirements.
The collection is marked circular, but the available information does not define what circular features apply to each model. Confirm any project-specific requirements, including finish availability and the exact product specification, before finalizing your selection. Myntwork offers these RIM Lambda chairs on a monthly lease, which may be useful when planning furniture for a changing workplace.
