“Retro” is a term that can mean many things in the world of interior decorating. It can refer to recreating the feel of the 1960s, ’70s, or even ’80s. But a retro bedroom design can also mean mixing old and new, classic and modern.

A retro theme is perfect for anyone decorating their bedroom on a budget, because you can often find appropriate furniture and accessories in thrift stores. The simplicity of this style also creates a feeling of comfort and relaxation, which is ideal for a place where you spend much of your time sleeping and lounging around.

Start with white or neutral colors on your walls and flooring, then build your theme around the use of bright colors, bold patterns and graphics for your artwork, bedding and window treatments. You don’t have to stick with one color; the design will have a more retro feel if you blend several of them together, such as electric blue, green and purple, or orange, yellow and pink. Squares and rectangles are common motifs, as are swirl designs; try mixing them together with some solid colors in your bedding and draperies to keep the décor from becoming too busy.

For furniture, select pieces that are low to the ground, with straight, simple lines. A second hand store is a good place to find some quality pieces of retro-style furniture at a reduced price. Older bedroom furniture was often sold in sets, so try looking for matching nightstands, dressers and vanities (the latter can double as a writing desk). Refinish the wood surfaces on your retro furniture to restore its natural beauty, or if you prefer, paint it the same bright colors as your artwork and bedding.

For lighting, consider using a large pendant light in the center of the room; a shaded floor lamp is ideal for use by your bed. Like your bedding and artwork, retro lampshades also come in bold colors and patterns. Lava lamps may be more decorative than functional, but you can use one as a nightlight, and they definitely go with the theme. Accessories such as vinyl chairs and band posters will also enhance your bedroom’s retro feel.

Create a lounge area that includes a comfortable sofa where you can retreat to watch television, read a book or browse the Internet on your laptop. Decorate it with a couple of colorful ceramic lamps and a soft, fluffy rug you can sink your toes into.
