mattresses

A mattress is a large, cushioned surface placed on a bed frame to support sleep. Most mattresses combine a comfort layer with a support core to cushion the body, distribute weight, and maintain spinal alignment during rest. Covers are typically removable and washable.

Common types include innerspring (coil) mattresses, foam mattresses, latex mattresses, and hybrids. Innerspring designs use metal springs with upholstery and a top comfort layer. Memory foam mattresses rely on viscoelastic foam that contours to the body. Latex mattresses use latex foam for resilience. Hybrids blend a coil core with foam or latex layers.

Materials influence feel, durability, and temperature regulation. Foam can soften with heat and slowly regain shape; memory foam offers pressure relief but may retain heat. Latex and many hybrids tend to sleep cooler and provide more buoyant support. Construction details such as edge support and motion isolation affect user experience.

Sizes include twin, twin XL, full, queen, king, and California king. Firmness is described as soft, medium, or firm and varies by model. Sleep position and body weight influence comfort preferences; side sleepers often prefer softer models, while back and stomach sleepers commonly choose firmer ones.

Care and lifespan: rotate or flip as advised, use a breathable protector, and keep the surface dry. Most mattresses last about 7 to 10 years, with sagging or reduced support signaling replacement.

Shopping considerations include budget, trial periods, warranties, and certifications such as CertiPUR-US or OEKO-TEX for foams and fabrics. Compatibility with existing foundations and return options are also important.
