End tables are going to be one of your least expensive furniture options. However, it is also going to allow you to create a theme in your space inexpensively.
You can use these options to create a theme or soften up the contemporary kind of look. You can find farmhouse styles of tables that even mimic more of a picnic table. These will be deceptively expensive but this also bridges the classic and contemporary design styles together.
If you shop at Horchow you're going to see a ton of crocodile or faux patent leather end tables. This is going to use a lot of nailhead kind of trim. Just make sure that this works well with your lighting fixture.
We are also seeing a lot of the retro kind of design styles. This uses more of a tiered table design. It might even use 3 tiers instead of two. You can readily find these pieces at a thrift store and then give it a fresh coat of paint for more of a modern kind of look.
Another style that's very popular is the Japanese or Asian design style. This uses simple aged brass hardware that's oversized. It can even be in the classic pagoda style. This will use a lot of black and you can use it to add an interesting element next to a basic black leather sofa.
Tray tables are also a popular design style. You can even find pieces with a removable tray. However, this can have a vintage design style with a painted tin tray on it. This will bring in metallic tones but in a very vintage and classic kind of way.
