Old conventional furniture can easily be used in your recording studio, but having custom designed furniture case for your Recording Studio does have its advantages. Most studio desks are built to give you the most efficient access to the most amount of equipment. This is done with adjustable, swivel, speaker stands to match the height of your ears when you are sitting in front of desk. Another common feature is sliding stands for the monitor, musical keyboard, or computer keyboard. Allowing you to reach all of the main components of your set up directly in front of you.
When sitting in your chair in front of your mixer, realize that anything within an arms reach of you is a prime location for whatever equipment you find yourself using most. When all of your gear is organized efficiently than you can begin maximizing your creative possibilities when laying down tracks.
The other vitally important piece of furniture in your recording studio is your chair. This may sound very trivial but when you think about it, it is the most used piece of furniture in the room. Recording studio engineers spend allot of time sitting, so why not sit in comfort. The more comfortable you are in your studio the less distracted you will be when trying to focus on a mix or a long session of recording.
