There are many different types of automotive functional cushions available on the market today. There are foam, gel, and Sheepskin types. These materials all have their pros and cons.

Memory foam
A firm cushion for your car seat is an excellent option for a comforting back rest. Made with high-density foam and topped with a gel layer, the firm cushion helps support the natural curve of your spine, which can prevent back pain, sciatica, and lumbar strain. Its firm design also helps to prevent degenerative disc disease. As for the material, some car seat cushions are made of sheepskin, which is a luxurious touch to your seat. Sheepskin has many benefits, including being durable, promoting good blood circulation, and healing sensitive skin.

Some types of memory foam can be quite uncomfortable to sit on, however. This is because memory foam has a tendency to retain heat. For a more comfortable summer seat, latex or polyurethane are a better choice. In addition, memory foam takes a while to adjust to its original shape. It is also not as elastic as regular foams, which have a springy feel.

Gel
The gel automotive functional cushion is designed to minimize the force of occupant seat pressure and to improve blood circulation in the body. Its design is based on a thermoplastic elastomer with small hexagonal cells that distribute pressure, reduce physical impact, and improve air permeability. Compared to the foam cushion, the gel automotive functional cushion provides more comfort and better blood circulation.

The gel automotive functional cushion has multiple layers to provide comfort to the user. The gel material is environmentally friendly and has high elasticity and strength. It also relieves fatigue and has long service life. Its double-decker structure is a honeycomb design, which is ergonomic. It is suitable for car seats, air seats, and wheelchairs.

Foam
Automotive functional cushions are made of many different materials, and one of the most common is foam. Foam is a flexible material that offers several advantages, including the ability to adapt to the needs of a specific vehicle. In addition to flexibility, foam provides durability and low weight. Automotive seats need a cushion that can absorb energy while remaining firm against dynamic forces. A popular choice is flexible polyurethane foam, which is very cost effective and can be molded into a variety of shapes.

The density of a foam is important in determining its durability. It is measured in pounds per cubic foot or kilograms per cubic meter. The higher the density, the more durable it is. The density of foam is directly related to the chemistry used to make it, as well as the additives used in its production.

Double-wall air-mat
The Double-wall air-mat for automotive functional cushion has two functions, a cool function and a heat function. The cooling function of this air-mat is used to maintain the cushion 3 at a comfortable temperature. The device also features a compact volume and a simple structure, which make it easy to assemble and disassemble.

The gel cushion was shown to provide more pressure relief compared to the foam cushion. This may be due to the gel cushion's ability to distribute and relieve pressure better than the foam cushion. This may have led to improved blood circulation and reduced pain. Nevertheless, this study has some limitations.
