Baggage size/dimension restrictions

[quik!]

I'm planning to get some furniture and was wondering if there are any size/dimension restrictions on the item (keeping in mind that the item weighs less than the allowed weight).

Thanks!

Look under the US section:

For non-US, the size requirements probably apply as well (they do on BA for example).
