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.  

== Acquisition ==  

Royal beds require the [[Research#{{P|Required Research}}|{{P|Required Research}}]] research project to be completed in order to be constructed. Each requires {{Required Resources}}, {{Ticks|{{P|Work To Make}}}} of work, and a [[{{P|Skill 1}}]] skill of {{P|Skill 1 Level}}.

[[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.

=== 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.

==Analysis==

'''Summary''': Royal beds are nice, but their advantages can usually be provided more cheaply and effectively by other means: the beauty by making a [[sculpture]], the rest effectiveness by making several regular beds and rolling for higher [[Quality#Structures|quality]]. Royal beds are practical for [[noble]] pawns who need them (i.e. Baron rank and higher), and for when your constructor has a [[Mental_inspiration#Inspired_creativity|creative inspiration]].

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 [[Room_stats#Impressiveness|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 tile|silver]] or even [[gold tile]]s.)  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 [[Quality#How_quality_is_determined|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 [[Ideoligion#Specialists|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 [[Mental_inspiration#Inspired_creativity|creative inspiration]], or (c) your constructor is bored, you've hit the quality ceiling on your regular beds, and you have resources to spare.
