Knowra Mattress Mattress A padded support for sleeping or reclining, typically placed on a bed frame or foundation. Its materials and construction shape comfort, support, temperature, and durability.
Innerspring mattress : A mattress supported by a network of metal coils, often layered with foam or fiber. Its coil core is the traditional alternative to all-foam construction.
Sleep posture : The position in which a person sleeps, such as on the side, back, or stomach. Different postures change which body areas need cushioning and support.
Futon : A flexible mattress that can be folded or laid flat, traditionally used in Japanese bedding. It serves sleeping and seating roles with a different form and construction.
Sleep quality : A description of how restorative and uninterrupted a person’s sleep is. Comfort, heat retention, and motion transfer can influence nighttime rest.
Memory foam : A viscoelastic polyurethane foam that softens with heat and slowly conforms under pressure. It molds around the body and changes how a mattress distributes pressure.
Pressure ulcer : Localized damage to skin and underlying tissue caused by sustained pressure or pressure combined with shear. Specialized mattresses can redistribute pressure for people at elevated risk.
Waterbed : A bed whose sleeping surface is supported by water-filled chambers. Its fluid support replaces the solid foam or spring core of most mattresses.
Indoor air quality : The condition of air inside buildings, shaped by pollutants, ventilation, and other factors. Some mattress materials and finishes release volatile compounds indoors.
Latex foam : Elastic foam made from natural rubber latex, synthetic latex, or both. Its springy response differs from the slower contouring of memory foam.
Motion isolation : The reduction of movement transmitted across a shared sleeping surface. It distinguishes mattress designs that limit disturbance from a partner’s movement.
