Double bed

A double bed costs almost twice as much as a regular bed, and 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

Double beds can be constructed once the Complex furniture research project has been completed. They require 85 Stuff (Metallic/Woody/Stony) 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 25% faster, and thus require 80% of the time to sleep.

Rest effectiveness varies by quality and material. With the notable exception of jade, stone materials only offer 90% of the rest effectiveness of a bed made from non-stone materials at the same quality level. Jade can safely be used to make beds with extremely high beauty and value.

Material	Awful	Poor	Normal	Good	Excellent	Masterwork	Legendary
Non-Stone and Jade	86% (12.21 hr)	92% (11.41 hr)	100% (10.5 hr)	108% (9.72 hr)	114% (9.21 hr)	125% (8.4 hr)	160% (6.56 hr)
+ Sleep accelerator	116% (9.04 hr)	124% (8.45 hr)	135% (7.78 hr)	146% (7.2 hr)	154% (6.82 hr)	169% (6.22 hr)	216% (4.86 hr)
Stone except Jade	77% (13.57 hr)	83% (12.68 hr)	90% (11.67 hr)	97% (10.8 hr)	103% (10.23 hr)	113% (9.33 hr)	144% (7.29 hr)
+ Sleep accelerator	108% (9.77 hr)	115% (9.13 hr)	125% (8.4 hr)	135% (7.78 hr)	143% (7.37 hr)	156% (6.72 hr)	200% (5.25 hr)

Comfort

Comfort is a measure of how high a pawn can refill their comfort meter while using the piece of furniture. A pawn sleeping in a bed with a higher comfort value can achieve a higher level. It does not affect the rate at which comfort increases only the maximum level. Comfort levels over 100% have no additional effect. 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	0.61	0.7	0.8	0.9	0.99	1.16	1.36
+ Dresser	0.61	0.7	0.8	0.9	0.99	1.16	1.36
+ 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 and bedrolls 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

Analysis

For a more complete discussion of "beds", see Bed#Analysis.

Double beds are just a bed that two can share; all stats and in-game effects are otherwise the same. Colonists get a −5 moodlet for sleeping with someone they have 0 opinion of (changing by +/- 1 for every 20 opinion). Conversely, pawns in a relationship will demand to sleep together, and will become upset when they aren't assigned to the same bed.

Double beds are ~.94 times as much work as making two standard "single" beds, and require 5 less material. However, because of the mood penalty, you should just build regular beds unless a relationship happens.
