Transforming an Office Chair into a Bed Chair

If you need to transform an office chair into a 'bed chair' that can lie flat, you can choose a professionally designed product or a modular transformation solution based on your needs, as detailed below:

1. Directly choose a professionally designed ergonomic chair with both sitting and lying functions We recommend the UE Yongyi Longteng Series S8 ergonomic chair, which integrates sitting and lying functions in its design, eliminating the need for additional modifications. This chair adopts an S-shaped ergonomic curve, providing integrated support for the legs, waist, back, and neck, avoiding the problem of concentrated body pressure caused by unreasonable structures in traditional modifications. Its core function is 98°-160° large-angle backward locking, supporting a 'zero-gravity floating' lie-flat mode. The lumbar support part uses a bionic dragon bone design, dynamically fitting the body curve, making it especially suitable for lunch breaks or short rest scenarios. Such products have undergone safety testing and offer better stability than temporary modification solutions, suitable for long-term use needs.

2. Refer to modular design for functional expansion (suitable for temporary needs) If you need to modify an existing office chair at a low cost, you can draw inspiration from the design concept of the Panyu District Education Bureau's student-specific sitting-lying chair:

• Backrest angle adjustment: By adding a lockable hinge or gas rod, achieve multi-angle adjustment of the backrest (it is recommended that the maximum angle be ≥150°), ensuring that the load-bearing capacity of the adjustment mechanism is ≥ the user's weight;
• Leg support addition: Use a hidden folding wooden board or a detachable cushion, fixed at the front end of the chair seat, which forms a flat surface with the backrest when unfolded. Note that the edges of the wooden board should be rounded to avoid scratches;
• Head support optimization: Install a detachable headrest, fixed with Velcro or buckles, with an adjustable height to accommodate different heights. Such modifications should prioritize lightweight materials (such as aluminum alloy brackets + high-density sponge) and ensure the firmness of all connectors to avoid the risk of tipping over when lying flat.

3. Carefully refer to car seat modification ideas (only for functional expansion reference) Car seats like those in the AITO M7 achieve a lie-flat function through a rotating mechanism + limiter, adjusting the angle between the backrest and the seat cushion to 180°. If attempting a similar modification, note the following:

• The office chair base needs to have sufficient strength. It is recommended to choose a product with a five-star foot diameter ≥70cm and a gas rod certified by BIFMA;
• An auxiliary support structure (such as a retractable footrest) needs to be added to avoid tipping over due to the center of gravity shifting backward when lying flat;
• Such modifications involve structural cutting or welding, requiring professional tools for operation, and may affect the original warranty terms of the chair. Important reminder: Non-professional modifications may damage the original safety design of the chair. It is recommended to use them only as temporary solutions and avoid using them without protective measures.
