Inflatable mattresses were once seen as stopgaps – fine for camping trips or the occasional guest, but rarely associated with comfort or real support. The problem was simple: they sagged, shifted, and looked temporary.
Patent US7353555B2 set out to change that. Instead of delivering a flimsy air bed, it introduces an inflatable mattress designed to mimic the structure of a pillow-top. With raised edges, internal beams, and a smoother finish, it offers a product that feels sturdier, more comfortable, and closer to a permanent bed.
It has even caught the attention of big players. This patent is currently at the center of a legal dispute between Dongguan Hongyu Plastic Co., Ltd. and Sun Pleasure Co., Ltd. But we are not diving into the litigation. We are focusing on what the technology brings to the table.
To do that, we used the Global Patent Search (GPS) tool. It helped us uncover four patents that explore similar goals: better support, firmer edges, and smarter inflatable structures.
Understanding Patent US7353555B2
US7353555B2 describes an inflatable mattress designed to go beyond basic portability. Its goal is to deliver a bed that feels closer to a traditional two-layer pillow-top.
The invention achieves this through a reinforced outer frame and built-in internal supports, which keep the mattress stable and reduce the sagging or bulging common in older designs. By combining these elements with a more polished, layered appearance, the patent outlines a mattress that looks and performs more like permanent bedding.

Its Key Features Are
1. Secure outer frame – The top edge of the mattress has a raised border fixed by two seams.
2. Pillow-top appearance – A groove along the sides gives the mattress a layered, premium look.
3. Internal Y-shaped beams – These support structures keep the mattress from bulging when inflated.
4. Connected air chambers – All parts of the mattress are linked, so it inflates through a single valve.
The mattress includes special corner construction for added comfort and seamless edges. It also uses curved surfaces and tensioned internal walls to keep its shape. A felt-like coating may cover the top for a softer feel. These added touches aim to improve comfort, stability, and visual appeal.
This design focuses on both appearance and function. And solves common issues like sagging and wrinkling.

2. US4991244A
This U.S. patent, US4991244A, published in 1991, introduces an inflatable bed system that combines air mattresses with a foam-based outer border. The design aims to confine the air mattresses within a firm but comfortable frame, using layered foam and secure fasteners.

What This Patent Introduces to the Landscape
- Framed air mattress system: Two side-by-side air mattresses are enclosed in a supportive rectangular foam border.
- Dual-layer foam border: Each wall of the border includes a soft upper layer and a firm lower layer.
- Pressure-limiting system: Relief valves prevent over-inflation and reduce the risk of seam rupture.
- Hook-and-loop fasteners: VELCRO joins the border walls, allowing quick assembly and disassembly.
- Removable outer cover: A zippered and drawstring cover encloses the mattress and frame for a secure fit.
- Foundation support: The structure sits on a base to raise the bed off the ground.
- Flexible configurations: Designed to support one or two air mattresses within the same framed setup.
How It Connects to US7353555B2
- Both patents focus on border reinforcement to reduce bulging and edge collapse.
- Each system improves the stability and appearance of inflatable beds.
- Both aim to mimic the look and function of traditional mattress structures.
- Each design uses layered components to combine firmness with surface comfort.

3. FR2542589A1
This French patent, FR2542589A1, published in 1984, introduces an inflatable structure made of flexible materials for creating mattresses and other furniture. It divides the inflatable body into sections with different air pressures to balance support and comfort.

What This Patent Introduces to the Landscape
- Multi-pressure zones: Separate areas are inflated at low and high pressures for comfort and support.
- Flexible internal spacers: Maintain the mattress shape and limit deformation under weight.
- Waterproof internal fabric: Divides the inflatable zones and keeps them airtight.
- Perimeter reinforcement: Uses glued strips and folded fabric for stronger edge construction.
- Optional third pressure layer: Adds mid-pressure volume to enhance stability without sacrificing softness.
- Rigid base option: A hard bottom layer or frame improves mattress firmness and portability.
- Foldable frame panels: Panels hinge together to create a foldable, rigid base for easier transport.
