Size:
A typical headboard for an adjustable bed is approximately 2 to 4 inches wider than the bed frame. However, some headboards are designed to be the exact size of your bed for a precise look. Though different bed types are differently sized -- i.e., king, queen, twin, and single, beds can have a discrepancy of a few inches within these sizes, so always measure. Andre Mellone states to leave at least a one-inch gap between each side of the bed and your chosen headboard. This will allow you to fit the headboard comfortably and will accommodate any sizing discrepancies. The height of a headboard is important, too. If you have a small bedroom, a tall headboard will overwhelm the wall space you do have, so it's best to go for a low to mid headboard, and vice versa for larger rooms.
Material:
The material of a headboard is important, as it will partially determine the style of a bedroom. A leather or faux leather headboard will look chic and sophisticated but is more suited to a modern bedroom. PU leather is a low maintenance material and can be easily maintained without specialist cleaning products, but real leather requires a bit more care so it does not get damaged over time. Alternatively, a headboard upholstered in fabric works well with all types of décor styles, including farmhouse, modern, and antique. For a mid-century modern look, a teak headboard will look cool and stylish. Wooden headboards can add rustic charm to your bedroom in general. Wood also allows you to get creative with your bedding due to its more neutral appearance.
Style and Color:
The color and style of a headboard for an adjustable bed are key, as you need to make sure your chosen headboard fits in with existing bedroom décor. For example, a headboard with tufting detail is suited to a vintage or less contemporary bedroom, whereas a studded leather headboard is ultra-modern and will lend edge to a room. Per Courtney McLeod, if in doubt it's always best to go for a neutral color and design, as this will still match most décor styles even if you decide to change things up. Certain colors like pink are stylish but not very versatile, whereas beige and taupe may feel a little dull but are a better long-term choice. Black is also a relatively neutral color, though it isn't the best option for narrow rooms.
