Royal bed

Royal Beds are highly resource-intensive to build, but they really liven up the beauty in a room, and also provide a slight bonus to the rate at which colonists recover during sleep, as well as lots of comfort for a good mood boost. So, it is generally wise to upgrade to them as time and resources permit.

Despite its name, it is part of the base game and not the Royalty DLC. It is however required for some content in that DLC, including keeping Nobles happy.

Acquisition

Royal beds require the Complex furniture research project to be completed in order to be constructed. Each requires 100 Stuff (Wood/Metals/Stone), 50 Gold, 50,000 ticks (13.89 mins) of work, and a Construction skill of 8.

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	90% (11.63 hr)	97% (10.87 hr)	105% (10 hr)	113% (9.26 hr)	120% (8.77 hr)	131% (8 hr)	168% (6.25 hr)
Stone except Jade	81% (12.92 hr)	87% (12.08 hr)	95% (11.11 hr)	102% (10.29 hr)	108% (9.75 hr)	118% (8.89 hr)	151% (6.94 hr)

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	0.68	0.79	0.9	1.01	1.12	1.31	1.53
+ End Table & Dresser	0.76	0.88	1	1.12	1.24	1.45	1.7

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

Analysis

The direct alternative to the royal bed is the regular double bed, or the bed if your pawn sleeps alone. All else being equal, the royal bed's rest effectiveness is 1.05x that of the regular beds, and its beauty and wealth are much higher (wealth helps maximize a bedroom's impressiveness but also attracts raiders).

However, the rest effectiveness bonus from a royal bed is less than the bonus from having a higher-quality bed, the difference increasing at higher qualities. A good royal bed has 1.13 rest effectiveness vs. an excellent bed's 1.14; excellent royal bed has 1.20 vs. masterwork bed's 1.25; masterwork royal bed has 1.31 vs. legendary bed's 1.6! (Comfort, meanwhile, maxes out at 1, which is reached by masterwork beds, or by an excellent bed with an end table and dresser. Beauty, in turn, is more efficiently obtained with sculptures: the base beauty of a royal bed is 75 for most materials, while one large sculpture has 100, or 135 if it's marble. And if you want to add wealth to your bedroom, you can use silver or even gold tiles.) Also, the sleep accelerator's bonus adds to the royal bed bonus, but is multiplied by the quality bonus.

Given this, if you're thinking of making a royal bed, ask if it's better to construct a bunch of regular beds and roll for higher quality (deconstructing the worse beds). The royal bed costs so much more that the higher-quality regular bed is not just better, but often cheaper and much faster to make—depending on the materials used and your constructor's skill.

A royal bed takes 33x the work of a double bed and 63x that of a single bed, regardless of materials. As for cost: If using wood, the market price is 7x the double bed and 13x the single bed—though much of the market price is from the work, and if you count only the price of the gold and wood, the royal bed is "only" 6x the double bed and 11.4x the single bed. (For more expensive materials, the cost ratio is smaller: the royal bed is, compared to double and single, 4.2x and 8x for steel, 2.3x and 4.4x for jade, 1.8x and 3.4x for plasteel, etc.) Therefore, using wood, for the same material cost as one royal bed you could construct 11 double beds (and deconstruct 10, recovering half the materials), spending only 1/3 the work (minus the hauling and deconstructing); for steel it's 7 double beds. Usually, this is more than enough to get higher quality.

Let's look at some examples. If your colonists all have good wooden double beds, and you're trying to give them the next level up—i.e. a good royal bed or an excellent double bed—then if, say, your constructor is level 10, then on average you need to make 2 royal beds or 8 double beds, which, taking deconstruction and relative costs into account, makes the royal bed approach cost 2x the materials and 8x the work. (There's also a 1/4 chance that the royal bed will be excellent.) At level 13, it's more like, to upgrade 3 colonists you construct either 4 royal beds (two are good, one is excellent) or 13 double beds (with a 1/5 chance that one is masterwork), for a cost ratio of 2.6x and work ratio of 11x. Substituting "steel" for "wood" makes royal beds relatively more appealing, but only by a factor of 1.42x, still less than the cost ratio.

Next, let's imagine your colonists have excellent beds. If your constructor is level 20, then, on average, to upgrade 6 of them, either you make 10 royal beds (getting 5 excellent and 1 masterwork), or you make 63 double beds (getting 6 masterwork); the royal approach costs 1.39x the materials and 5.2x the labor. (For steel, the royal approach costs 0.97x as much.) Rolling for masterworks at lower levels gets worse quickly; at level 18 you need 99 double beds vs roughly 13 royal beds, but the royal approach is still a few percent more expensive. At 17 and below, royal beds are cheaper. (Though at level 15 and below, you're making 3 royal beds to get every 1 excellent+ bed, and you might want to train your constructor more first; likewise, rolling for masterworks is probably best started no earlier than, say, level 19.)

If your constructor is a production specialist, then all quality levels are increased by 1 in the above. The amazing 1.6 rest effectiveness of legendary beds becomes paramount: going "masterwork bed -> legendary bed" saves 4.5x the colonist waking hours as going "masterwork bed -> masterwork royal bed". Therefore, even if you're using steel, rolling for legendary beds is worthwhile (despite being 3% more expensive per bed than masterwork royal beds at level 20), and doubly worthwhile for single beds. (Also, the 2.5x masterwork market price factor overpowers the 0.7x furniture sell price factor, and with a decent negotiator it should be profitable to sell the discarded masterworks and buy the raw resources they're made of.)

In conclusion, royal beds are usually not practical for most pawns, which should instead be given higher-quality regular beds (single or double) plus sculptures. Royal beds are appropriate for (a) noble pawns, (b) if your constructor has a creative inspiration, or (c) your constructor is bored, you've hit the quality ceiling on your regular beds, and you have resources to spare.
