Wood
There are two main types of wood - hardwoods and softwoods.
Hard woods
Hard woods come from broad leaved trees. These trees have flowers
and produce seeds such as nuts and fruit). Examples are oak, beech
and mahogany.
Hardwoods are denser than softwoods and are stronger and more durable
too. They are used for furniture making. Beech is often used for making
toys. Hardwoods are much more expensive than softwoods.

MDF (medium density fibreboard) is now widely used.
Plywood made up from alternating layers of thin sheets
of wood is strong in all directions.
Chipboard made from softwood chips and sawdust is
cheap but only attractive when coated with melamine – used for
kitchen cupboards (carcases).
