There are many traditions associated with both chambers of the Houses of Parliament. The Woolsack, for instance, is a sort of stool stuffed with wool, originally placed in Parliament in Edward III's reign as a symbol of the basis of England's prosperity at that time. Nowadays, it is the seat of the Lord Chancellor, as Speaker of the House of Lords and is significantly stuffed with a blend of wool from the colonies and dominions.
There is a place between the two sides of the Houses. In the Houses of Commons this space is approximately the width of two drawn swords. Formerly,the MP's, when very heated, sometimes drew swords and a figk began.Therefore, a ruler was imposed prohibiting members to cross the space. Today any MP who puts a foot forward is "called to amber" immediately by the Speaker and he has to apologise to the House.
