That's an excellent and very practical question! As a taller person, you're right to think about dimensions before choosing a garden bench. The short answer is yes, garden benches absolutely vary in both depth (from front to back) and height (from the ground to the seat). Finding the right proportions is key to your comfort.
Standard benches often have a seat depth of about 18-20 inches and a seat height around 18 inches. For someone tall, a shallow seat can leave your thighs unsupported, and a low seat can make standing up awkward.
Look for benches described as "deep-seated" or with "extra depth," often ranging from 21 to 24 inches. This provides crucial support for your upper legs. Similarly, a seat height of 19-20 inches can be more comfortable for longer legs. Don't forget backrest height; a taller back (above 24 inches) can support your shoulders.
Consider benches with a slight downward slope from front to back and armrests at the correct level to aid in sitting and standing. Materials matter, too—firm, supportive cushions on a deep frame are ideal.
Your height is an advantage in seeking true comfort. By paying attention to these specs, you can find a bench where you can truly relax and enjoy your garden for hours.
