Each Allform piece varies by components which will alter the dimensions of your product. Having said that, here is how to understand the dimensions of your piece:
Width: The measurement from left to right when you are staring directly, head on to your product.
For example: The width of a 3-seat sofa is 90".
Depth: The measurement from front to back when you are staring directly, head on to your product. This measurement can vary depending on if you choose a chaise and/or a corner sectional.
Example #1: The depth of a 3-seat sofa is 38".
Example #2: The depth of a 3-seat sofa with chaise is 61".
Height: The measurement from the top of the back of the sofa to the floor. The height on every Allform piece is 34".
