During the War of the Roses the Duke of Somerset changed sides from the Lancastrians to the Yorkists. For King Edward it was a bit of a coup as Somerset was the best of the Lancastrian commanders, however, for Yorkists like Hastings it was both a threat to their influence with the King and a risk as Somerset was not trusted - and rightly so as he soon went back to Henry and the Lancastrians.

The odd thing at the time was how much Edward took to Somerset. They shared a bed, they went hunting together; all great displays of male on male intimacy in the English Middle Ages. However, unlike the Greeks and Romans, it wasn't fully as intimate as 20thC culture would expect from two men sleeping together. Desmond Seward writes:

One should not read any hint of homosexuality into Somerset being 'lodged' in Edward's bed. Until the present century hospitable peasants in some parts of Europe would invite guests to share the family bed, and during the fifteenth century even monarchs owned very little furniture.

The royal bed would have been distinguished for its size and rich materials - coverlets of silk and fur, down pillows - besides being swathed in elaborate curtains to keep out the draughts of winter.

Indeed, it was such a precious object that Richard III took his with him on campaign, his money chest concealed underneath a secret compartment.

So it is more a function of the scarcity of furniture and the rare opulence of the royal bed that led to the nobles sleeping together. It is unfathomable in this day and age which has left the industrial revolution behind and entered the digital revolution that a cheap commodity object like a bed would be so exclusive that only monarchs and nobles had bed furniture.
