Building a backless wooden garden bench

Updated February 21, 2017

Backless garden benches may be made from a variety of different materials. Boulders attached by a sheet of rock or wooden slats sitting atop a wrought iron stand make equally beautiful backless garden benches. You can find materials at your local landscape supply and home improvement store, or you can use found objects like the bottom of a chair or the seat from an old wooden picnic table, repurposed for a bench in your garden. Building a backless garden bench is a simple process once you gather the types of materials that will work best for you. Always use treated wood when building anything that will sit outside. Teak, redwood and cedar are popular choices for wooden garden benches. You can use a waterproof adhesive to attach the bench seat to the frame if you're using rocks or metal, or you can use screws or nails if you are only working with wood. Remember to buy a brace to hold the wooden slats together if make a wooden seat.


Creating the seat for your wooden garden bench may entail attaching two to four wooden slats together using a metal brace across the bottom, close to each end. Once you have your slatted seat assembled, secure it to the two boulder bases with liquid nail. You may also choose to drill holes in the rock and use masonry screws to attach the wooden seat. If your base is wrought iron, you can use the same techniques for securing the backless wooden seat. Building a wooden base is also a simple process. Using the same treated wood you used for the seat, build a three-sided rectangle for each end of the bench. Add a treated wood brace diagonally across the frame.


If your bench is more than 60 cm (2 feet) long, add another frame piece in the middle for support. You can also double the width of the rectangle by using two pieces of treated wood, attached together from the back. This will create a thicker, sturdier garden bench.


The great thing about backless wooden benches is that they can fit in almost anywhere in the garden. Placed against a tree or sitting in a flower bed, the backless bench can blend into your landscape more easily than other benches. They can also be placed between two walkways as they can be accessed from either side. If your wooden garden bench is in direct sunlight, treat it with wood sealant twice each year rather than the expected and accepted once annually.
