Precautions:

• Before installation, check that all accessories are complete to avoid interruptions due to missing parts.
• When tightening screws, do it in stages (e.g., tighten lightly first, then reinforce) to prevent slipping or uneven force.
• The gas lift should be inserted vertically to avoid air leakage or damage caused by tilting.
• Ensure that the screws at the connection between the backrest and the seat cushion are fully tightened to prevent loosening during use.
