The advent of folding beds has brought convenience to people's lives, and some have even applied for patents for them. An adjustable folding bed-chair consists of a bed frame, a movable seat, foldable footboards, bed frame legs, front and rear bed rails, etc. Its key feature is that by combining these components, a bed and a chair with a tabletop can be formed. This invention is highly user-friendly, with functionality far exceeding that of the lift-up hospital beds used in large hospitals. These beds have a small backrest adjustment angle, can only be used for lying down, require a small table for meals, and are relatively expensive. This invention completely overcomes these shortcomings, allowing for both lying down and sitting, with a separate tabletop for patient use. The chair's backrest has a large adjustment angle, and the bed can be folded into a flat surface, making it extremely convenient for storage and transport.
In terms of materials, folding beds are available in bamboo, wood, metal, Oxford cloth, and Teslin, among others.
Early folding beds made of bamboo, wood, and metal primarily used a bi-fold folding method. This type of folding bed has six legs and can be folded up to form a flat surface. It is characterized by its rigid structure, relatively heavy weight, and large size. Therefore, it is mainly used at home. It is produced and sold in various regions.
Additionally, folding beds made of Oxford cloth or Teslin fabric use soft Oxford cloth or Teslin fabric for the bed surface. The main structure is a "skeleton" made of round steel tubes, similar to an articulation principle. The folding method is more flexible and diverse, and it can be folded into a recliner. Its characteristics are: softness, light weight, and small size. It is widely used in homes, offices, for lunch breaks, and for leisure. Due to its flexibility, lightness, low price, and wide range of uses, this type of folding bed is also known as: folding recliner, folding chair, nap chair, nap bed, nap bed, camp bed, etc. The names vary depending on the region.
