Slab bed

Slab beds are a type of furniture added by the Ideology DLC. They are a variant of the regular bed that provides no comfort to their users but does provide a mood boost to those with the correct precept.

Acquisition

Constructing a slab bed requires Complex Furniture to be researched, 30 Stuff (Metallic/Woody/Stony, 300 for SMVs), and 400 ticks (6.67 secs) of work.

Summary

Slab beds function as do other beds, but provide no comfort to their users. Instead, they provide a +2 "slept on slab bed" mood buff to pawns with an ideoligion with the Slab bed preferred precept. As of 1.3.3117, the end table and dresser are as related options to build when the slab bed is selected, and the dresser is shown as linking to the it as well, but neither facility improves the bed.

Otherwise, their bed stats act as they do on other beds.

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

^{Bracketed numbers are in-game hours to refill rest from 0% to 100% at the given rest effectiveness.}

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

Costing fewer materials, requiring less work and increasing wealth less, while also providing the same benefits as a normal bed makes slab beds an obvious choice for pawns with the Comfort Ignored precept.

For other pawns, the loss of comfort can lose a significant mood buff and even inflict unfortable mood penalties. This is especially relevant for pawns that don't sit at their jobs and thus cannot benefit from armchairs. Generally the small but numerous benefits of the slab bed don't justify losing this buff.

Indeed, the real comparison is not between the slab bed and a regular bed for such pawns, but whether the precept itself should be taken at all. The +2 mood buff is nice, as is avoiding comfort penalties otherwise, but the buff is small compared to the +10 possible for comfort and keeping pawns comfortable is not particularly difficult in most games.
