Garden sleepers, also known as landscape timbers or railway sleepers, are long, rectangular pieces of wood that are used in landscaping and gardening projects. They are often used to create retaining walls, raised beds, and edging for gardens and flower beds. Sleepers are typically made from treated wood, which is resistant to rot and insect damage, and are available in a variety of sizes and styles to suit different needs and preferences. They can be used to create a natural, rustic look in a garden, or can be painted or stained to match the surrounding environment. In addition to their use in landscaping, sleepers are also commonly used as support beams in construction projects.
