Double bed

A double bed costs twice as much as a regular bed, yet provides the same rest. They are a good alternative if you have married colonists or lovers, who will get a mood penalty if not sleeping together.

Acquisition

Constructing a double bed requires Complex Furniture to be researched, 85 Stuff (Wood/Metals/Stone), and 1,500 ticks (25 secs) of work.

Summary

Rest Effectiveness

Rest Effectiveness is a measure how fast a pawn will regain rest. A pawn sleeping in a bed with 125% rest effectiveness would regain rest 125% faster, and thus require 80% of the time to sleep. Rest effectiveness varies by quality and material. Stone materials only offer 90% of the rest effectiveness of a bed made from non-stone materials at the same quality level.

Material	Awful	Poor	Normal	Good	Excellent	Masterwork	Legendary
Non-Stone and Jade	86%	92%	100%	108%	114%	125%	160%
Stone except Jade	77%	83%	90%	97%	103%	113%	144%

Comfort

Comfort is a measure of how fast a pawn will refill their comfort meter. A pawn sleeping in a bed with a higher comfort value will regain comfort proportionally faster. Comfort varies by quality but not material. Beds of the same quality level will all have the same comfort, regardless of what they're constructed from. An adjacent end table and a nearby dresser will each increase the base comfort by a further +0.05. This increase is applied before the quality multiplier.

Quality	Awful	Poor	Normal	Good	Excellent	Masterwork	Legendary
Comfort	0.57	0.66	0.75	0.84	0.93	1.09	1.28
+ End Table & Dresser	0.65	0.75	0.85	0.95	1.05	1.23	1.45

Surgery Success Chance Factor

The Surgery Success Chance Factor is exactly what it sounds like - a multiplier on the chance for a successful surgery assuming it is performed in this bed. The base value depends on the bed type with most beds having a base value of 100%, the sleeping spot a lower value of 70%, and the hospital bed a higher value of 110%. This base value is then modified by the bed's quality level. Beds of the same type and quality level will all have the same factor, regardless of what they're constructed from.

Quality	Awful	Poor	Normal	Good	Excellent	Masterwork	Legendary
Surgery Success Chance Factor	90	95	100	105	110	115	130
