Comfy Casting

From 2nd level, while sitting in a chair you are always comfortable. 

Also, when you cast spells while seated or prone, you can choose to forgo either the verbal or somatic components (but not both, and any material components are still required). 

Extra Padding

From 2nd level, any place you sit slowly (over a pwriod of 24 hours) turns into a comfortable lush, and padded chair. 

Also, you may add half your intelligence modifier (rounded up, minimum of 1) your AC while not wearing any armour. 

Cushions Abound

At 6th level you never travel anywhere withiut your cusions; over 10 minutes you can conjure magical cushions which guarantee a good nights rest. You can have up to 3 cushions at a time and each lasts up to 24 hours. 

As a reaction you may interpose one of these cushions between yourself any any weapon, spell, or other affect which would deal damage to you, granting you resistance to all damage that attack dealt in an explosion of feathers. 

Soft Footed

From 10th level, everyone elses lack of comfort is genuinely upsetting. Once per day, you can take 10 minutes to perform The Ritual of Ultimate Comfort. When the ritual is completed, perfectly fitting colourful fluffy slippers are conjured onto the feet of every creatures within 300 feet of you - so long as they have feet (sorry snakes). Creatures already wearing shoes gain oversized slippers which appear on the outside of their existing shoes. There is no size limit on the creatures which this ritual can affect (big or small), only that they must have clearly definable feet. 

The ritual requires and consumes gold thread - almost like wool - worth 75 gold. 

Also, you wouldnt want to scuff your comfy slippers would you? Your walking speed is halved but you have a flying speed equal to your normal (non halved) walking speed 

Well upholstered

Starting at 14th level, you can become the couch. Literally. As a bonus action you may assume the form of a three-seater, soft couch, in the colour of the robes you were wearing. If you are the couch, you may use your bonus action to transform back into your normal form. . 

When you become the couch you are an object (you are not considered a creature at this time) and have hit points equal to three times your Wizard level.  As a couch you are immune to being charmed poisoned possessed dominated paralysed petrified diseased and stunned, have immunity to psychic damage, resistance to all other damage except fire damage - you have vulnerability to fire damage. Additionally, creatures with an intelligence of 8 or less wont perceive you as a threat and will treat you as an object.  If your couch-form is reduced to 0 hit points, you fall prone in the same space on the hitpoints you were on prior to becoming the couch, and cant become the couch again until you complete a long rest. any extra hit points are not carried over to your non-form when your couch-form is destroyed.

On the other hand, as a couch you have a speed of 0 and may not take any action, reaction, or bonus action, except to transform back into your non-couch form.
