Frequently Asked Questions - CTZ-55 Yamazen
How do I assemble the Yamazen CTZ-55 chair?
Follow the included step-by-step manual. Typically, attach the backrest to the seat base, then insert the gas lift into the base, and finally attach the casters. Use the provided hex key for all bolts.
How can I adjust the seat height?
Locate the height-adjustment lever beneath the seat. Pull it upward while lifting fully off the chair, then release once you reach the desired height. The gas lift provides a range of 40–50 cm.
How do I clean the mesh backrest?
Use a soft brush or vacuum with an upholstery attachment to remove dust. For stains, gently dab with a damp cloth and mild soap, then allow it to air dry completely.
What is the maximum weight capacity of this chair?
The Yamazen CTZ-55 is rated for 120 kg (264 lbs). This capacity is tested under normal office conditions; exceeding it may affect stability and safety.
Can the armrests be removed?
Yes, the armrests can be removed by loosening the bolts underneath the seat with the provided hex key. This allows for a slimmer profile and more flexibility.
What tools are needed for assembly?
All necessary tools are included in the package, typically a hex key (Allen wrench). If you prefer, you can also use your own screwdriver for quicker tightening, but it's not required.
How do I adjust the recline tension?
The recline tension can be adjusted by turning the tension knob located under the front edge of the seat. Rotate clockwise for a firmer recline, counterclockwise for a softer one.
What are the shipping box dimensions?
The chair ships in a box measuring 80 x 60 x 30 cm (31.5 x 23.6 x 11.8 inches). The gross weight is approximately 17 kg.
How do I replace a broken caster?
Pull the old caster directly out of the nylon base using a firm, straight pull. Insert the new caster into the same hole and press until it clicks. Ensure all casters are locked before use.
Does the CTZ-55 come with a warranty?
Yes, it includes a 1-year limited warranty covering manufacturing defects. Contact Yamazen customer support with your purchase receipt and model serial number to file a claim.
