Cushion & Mattress
Both cushions and mattresses provide comfort and support, they differ significantly in their primary function, size, and typical use:

Cushion: is A soft pillow or pad, typically a bag made of cloth or other material filled with soft material (like feathers, foam, fiberfill).
Cushions are generally smaller and are used for various purposes beyond just sleeping. They are designed to provide comfort or support for sitting, leaning against, or kneeling such as
Sofa cushions for comfort on a couch.
Throw pillows for decoration or added comfort on a bed or chair.
Chair pads to soften a hard seat.
Wedge cushions for specific ergonomic support (e.g., for back sleepers, acid reflux).
Bolster pillows for neck or knee support.
Versatility: Cushions are often portable and can be used temporarily in various locations.

Mattress: is A large, usually rectangular pad, typically a fabric case filled with resilient material (such as coiled springs, foam, latex, cotton, or a combination) used primarily as a bed or on a bedstead for sleeping.
The main purpose of a mattress is to provide a comfortable and supportive surface for an individual to lie down and sleep on for extended periods such as
Innerspring mattresses
Memory foam mattresses
Latex mattresses
Hybrid mattresses (combining springs and foam)
Air mattresses (inflatable)
Mattresses are engineered to provide comprehensive body support, aiming for proper spinal alignment and pressure relief during sleep.
Mattresses are generally much larger and are typically placed on a bed frame or a solid foundation. They are integral to a bed setup.
Cushion as an accessory for comfort or localized support, often smaller and more versatile.
A mattress, on the other hand, is the primary sleeping surface, designed for full-body support over many hours.
Both of them use the quick dry foam inside, and should cover by solution dyed acrylic fabric.
