In woodworking, veneer refers to thin slices of wood, usually thinner than 3 mm (1/8 inch), that are typically glued onto core panels (typically, wood, particle board or medium-density fiberboard) to produce flat panels such as doors, tops and panels for cabinets, parquet floors and parts of furniture. They are also used in marquetry. Plywood consists of three or more layers of veneer, each glued with its grain at right angles to adjacent layers for strength. Veneer beading is a thin layer of decorative edging placed around objects, such as jewelry boxes. Veener is also a type of manufactured board. Veneer is obtained either by "peeling" the trunk of a tree or by slicing large rectangular blocks of wood known as flitches. The appearance of the grain and figure in wood comes from slicing through the growth rings of a tree and depends upon the angle at which the wood is sliced.
Particle board, or particleboard (or chipboard in the UK, Australia, New Zealand and some other countries), is an engineered wood product manufactured from wood particles, such as wood chips, sawmill shavings, or even saw dust, and a synthetic resin or other suitable binder, which is pressed and extruded. Particleboard is a composite material.
Particleboard is cheaper, denser and more uniform than conventional wood and plywood and is substituted for them when appearance and strength are less important than cost. However, particleboard can be made more attractive by painting or the use of wood veneers that are glued onto surfaces that will be visible. Though it is denser than conventional wood, it is the lightest and weakest type of fiberboard, except for insulation board. Medium-density fibreboard and hardboard, also called high-density fiberboard, are stronger and denser than particleboard. Different grades of particleboard have different densities, with higher density connoting greater strength and greater resistance to failure of screw fasteners.
MDF - MEDIUM-DENSITY FIBREBOARD
MDF is an engineered wood product formed by breaking down hardwood or softwood residuals into wood fibers, often in a defibrator, combining it with wax and a resin binder, and forming panels by applying high temperature and pressure.MDF is more dense than plywood.
It is made up of separated fibers, (not wood veneers) but can be used as a building material similar in application to plywood. It is stronger and much more dense than normal particle board. Comparison to natural woods. MDF does not contain knots or rings, making it more uniform than natural woods during cutting and in service. However, MDF is not entirely isotropic like metal, since the fibers are pressed together primarily through the sheet. Like natural wood, MDF may split when woodscrews are installed without pilot holes, and MDF may be glued, doweled or laminated, but smooth-shank nails do not hold well.
Leather Match upholstery (sofas, loveseats, chairs, etc.) typically has real leather where your body touches the piece during normal use. The rest of the item will be covered with vinyl. For sofas, loveseats and chairs, real leather covers the seat, the backrest and the tops of arms. Vinyl covers back and bottom. Leather match ottomans have leather only on the top. Reclining furniture varies by manufacturer.
Bonded leather or reconstituted leather is a material made of varying degrees of genuine leather combined with other substances to give the appearance of leather, but at reduced cost compared to natural leather. Examples of products that are most commonly constructed with different varieties of "bonded leather" are: furniture (sofas, loveseats, chairs, etc.), art books, desk accessories, bags, belts, etc.
