A grid-top foundation bed base is a type of bed foundation that features a grid-like structure made of metal or wood slats. The slats are spaced apart to provide support for a mattress and improve airflow to keep the mattress cool and dry.
A bed base, sometimes called a foundation, is the part of a bed that supports the mattress. The bed base can itself be held in place and framed by the bedstead ( bed frame ). In the United States, box-spring bed bases are very common (to the point where 'bed base' and 'box spring' may be used synonymously, and the term "platform bed" is used ...
A daybed is a couch that is used as a seat by day and as a bed by night. Usually it has pop up trundle which is used as bed in the night. A futon is a traditional style of Japanese bed using a mattress on a wooden frame. Futons are also available in a larger Western style which can fold halfway for sitting.
Mattress toppers are generally structurally similar to futons, are often made of similar materials, and (in the case of twin-bed toppers) have similar dimensions. Note the tufting. Museum samples demonstrating a 1590s bed : the bedcords , bedmat, three tick mattresses in dun and striped ticking , and the bedlinen.
Mattress coils, also known as mattress springs, are coil springs used in a mattress. Coils are primarily used in the core (support layer) of innerspring mattresses , which is their original use. In recent years, small "micro-coils" are being used in the upholstery (comfort layer) of mattresses, primarily with a coil core ("coil-on-coil ...
The Law of Original Horizontality states that beds are deposited horizontally due to gravity. If the beds are not horizontal, then that is an indication that they have been tilted or warped by geologic processes. [21] The Law of Lateral Continuity states that the bed deposits extend laterally in all directions. This implies that two places ...
The Zero Gravity Research Facility was built in 1966 as part of NASA's Centaur upper-stage rocket development program. In order to ensure proper firing and functioning of upper-stage rockets, NASA needed to understand the behavior of fluids (importantly, the liquid gases fueling the rockets), in the reduced gravity where they would fire.
It looks like a conventional bed and is designed to fit existing bedroom furniture. The platform usually looks like a conventional foundation or box spring, and sits atop a reinforced metal frame. Early waterbed mattresses, and many inexpensive modern mattresses, have a single water chamber.
