# Which size King Koil air mattress should I buy?

The King Koil Queen at 16" is the sensible default for two adults sharing at $139.95 (compare-at $159.95, per the merchant). Twin ($109.95) and Full ($129.95) suit one sleeper with less or more room, California King ($169.95) is the largest and priciest option for two adults who want extra length, and Kids ($79.95) is sized for one child and comes only in 13". This is a single-brand catalog, so it is a sizing guide within one line rather than a cross-brand comparison.

The honest shape of this answer first: this catalog carries exactly one air mattress brand, King Koil, sold under the name 'Luxury Air Mattress' across five sizes. Nothing here is checked against Coleman, Intex, SoundAsleep, or any other air-mattress maker — there is no cross-brand comparison to offer, only a walk through King Koil's own lineup. The five sizes share identical construction, pump, warranty, shipping, and return terms; what changes size to size is footprint, price, and how many height options each size offers.

At the shared 16" height, the ladder runs: Twin $109.95 (compare-at $129.95), Full $129.95 (compare-at $149.95), Queen $139.95 (compare-at $159.95), and California King $169.95 (compare-at $189.95) — twenty dollars from Twin up to Full, ten more from Full to Queen, and thirty more from Queen to California King. Twin fits one sleeper. Full still fits one person but with more room to spread out, or can work for two smaller kids sharing. Queen is the standard pick for two adults sharing a bed, which is why it is the default recommendation here. California King adds more length than Queen and is priced for two adults who specifically want the larger footprint; it is also the most expensive mattress in the lineup, thirty dollars over Queen at every one of the three matching heights. Kids does not participate in this 16" ladder at all — it is sold only at 13", at $79.95 (compare-at $99.95), and is sized for a single child rather than an adult.

Color choice narrows at the 13" height for four of the five sizes: Twin and Queen's 13" comes in Beige or Black only, with Blue reserved for their 16" and 20" heights, and Full and California King's 13" comes in Black only. Kids, which exists only at 13", offers both of its colors — Black and Blue — at that one height. Separately, every one of the thirteen size-and-height combinations in this catalog is discounted by exactly the same flat twenty dollars off its own compare-at price, which means the percentage saved is largest on the cheapest item (Kids, just over twenty percent off) and smallest on the priciest (California King at 20", ten percent off), even though the dollar saving never changes. King Koil's own site banner also claims 'CNN Underscored #1 Ranked (2026)' for this line; that is the merchant's claim about itself, not a rating this site has verified, so treat it as marketing copy rather than an independent endorsement.

Every price above is the merchant's sale price recorded from King Koil's own product feed on 2026-09-07, alongside a struck-through compare-at price listed next to it — both figures can change after that date, so treat them as a snapshot, not a standing offer. Warranty (1 year), returns (30 days), shipping (2-3 business days), and the pump (120V/210W, built in) are identical across all five sizes, all per the merchant rather than independently tested by this site. Nothing here is a claim about comfort, firmness, leak resistance, or durability — none of these mattresses have been tested by this site, and the 'Enhanced Coil Technology' construction description is King Koil's own wording, not an independent measurement.

Who this is NOT for: anyone who wants a second brand to weigh King Koil against — this catalog has nothing else to offer for that comparison. It is also not for anyone shopping by exact bed dimensions in inches; King Koil's own listings name sizes as Twin, Full, Queen, California King, and Kids without publishing a length-by-width spec, so this answer sticks to sleeper count and relative footprint rather than inventing numbers the merchant does not provide. And it is not for buyers who need every color at every height — Blue drops out of the 13" option on four of the five sizes.
