DETAILED DESCRIPTION OF THE EMBODIMENTS

(17) To make the purposes, technical solutions, and advantages of the present disclosure clearer, the following further describes the present disclosure in detail with reference to the accompanying drawings. Apparently, the described embodiments are merely some rather than all of embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without any creative efforts shall fall within the protection scope of the present disclosure.

(18) It should be noted that, the terms include, comprise, or any other variants are intended to cover non-exclusive inclusion, so that a commodity or device including a series of elements includes not only those elements but also other elements not explicitly listed, or further includes inherent elements of such commodity or device. An element defined by includes a . . . does not, without more constraints, preclude the existence of additional identical elements in the commodity or device that includes the element.

(19) It can be known from the background that an existing modular sofa still has a plurality of limitations and is low in practicability. Specific problems are as follows:

(20) According to a modular sofa in the prior art, sofa and bed functions are usually separated, and requirements of two functions cannot be met at the same time. In addition, a bed-forming function needs to be implemented by using an additional module, which increases purchase costs of a consumer and space occupation, resulting in a waste of resources.

(21) An existing sofa bed product usually exceeds 130 inches in a package size, which not only increases transportation space and human costs of an express delivery company, but also makes product carrying more difficult. For the consumer, this means higher purchase and movement costs, particularly challenges faced during moving.

(22) An existing modular sofa design is relatively fixed in a combination manner and cannot meet requirements of different families for personalized combination. Most products only provide a basic sofa function and lack an ability to convert into sofa beds.

(23) Assembly of an existing modular sofa usually requires an additional tool and connecting member, which not only increases complexity of mounting, but also affects use experience of the consumer and immediate usability of the product due to possible accessory missing during manual operation.

(24) The existing modular sofa design does not consider a storage requirement, and particularly, in a small-sized apartment, storage space is extremely valuable. However, an existing sofa design does not provide an effective storage solution.

(25) In view of the above problem, the present invention provides an improved modular sofa design, aiming to overcome at least one or more deficiencies in the prior art.

(26) Optional embodiments of the present disclosure are described below in detail with reference to the accompanying drawings.

(27) FIG. 1 to FIG. 8 are various modules that may be involved in a modular sofa according to some embodiments of the present disclosure, which are a single seat module 10, a pull-out sofa bed module 20, a corner seat module 30, an ottoman module 40, an armrest module 50, a love seat module 60 sequentially.
