Medieval wealth measured in—beds??

Alison Weir's Henry VIII King & Court: 

“A person’s wealth was often measured by the number of beds he owned: because of their carved decoration and sets of rich hangings, beds were usually the most valuable pieces of furniture” and were often bequeathed in wills."

Naturally, Henry had many beds.

He slept on not less than eight mattresses, and his Windsor bed was 11’ square. The fanciest ‘beds of estate’ were used for the ceremonial rising and retiring, and he had other (smaller) beds for actually sleeping in.

While most people slept on the floor or on straw mattresses, the wealthy had feather beds. Henry’s bed coverings were of the finest material: silk, velvet, and fur. The four post bed debuted late in Henry’s reign.
