A bed is a piece of furniture which is used as a place to sleep or relax.

Most modern beds consist of a soft, cushioned mattress on a bed frame, the mattress resting either on a solid base, often wood slats, or a sprung base.

Many beds include a box spring inner-sprung base, which is a large mattress-sized box containing wood and springs that provide additional support and suspension for the mattress.

Beds are available in many sizes, ranging from infant-sized bassinets and cribs, to small beds for a single person or adult, to large queen and king-size beds designed for two people.

While most beds are single mattresses on a fixed frame, there are other varieties, such as the murphy bed, which folds into a wall, the sofa bed, which folds out of a sofa, and the bunk bed, which provides two mattresses on two tiers.

Temporary beds include the inflatable air mattress and the folding camp cot.

Some beds contain neither a padded mattress nor a bed frame, such as the hammock, which is considered one of the most comfortable places to rest while swaying side to side.

Some beds are made especially for animals.

Teak (Tectona grandis) is a tropical hardwood tree species placed in the flowering plant family Lamiaceae.

Tectona grandis is a large, deciduous tree that occurs in mixed hardwood forests.

It has small, fragrant white flowers and large papery leaves that are often hairy on the lower surface.

It is sometimes known as the "Burmese teak".

Teak wood has a leather-like smell when it is freshly milled.

It is particularly valued for its durability and water resistance, and is used for boat building, exterior construction, veneer, furniture, carving, turnings, and other small wood projects.

Tectona grandis is native to south and southeast Asia, mainly India, Sri Lanka, Indonesia, Malaysia, Thailand, Myanmar and Bangladesh but is naturalised and cultivated in many countries in Africa and the Caribbean.

Myanmar's teak forests account for nearly half of the world's naturally occurring teak.
