# What is the best air mattress for overnight guests?

The King Koil Queen at 20" is the guest-bed pick at $149.95 (compare-at $169.95): of the three heights, 20" sits closest to a real bed's height off the floor. If saving a little money matters more than those extra inches, the same Queen at 16" is the value pick at $139.95 (compare-at $159.95). Full and California King sit one size down and one size up from Queen, for a single guest or two guests wanting more room, respectively. This is a single-brand catalog, so it is a pick within King Koil's lineup rather than a comparison against other brands.

The honest shape of this answer first: this catalog carries one air mattress brand, King Koil, so 'best for guests' means best within that single line, not a rating against Coleman, Intex, or any other maker — none of those appear in this data. Height is the only spec here that plausibly matters for a guest bed's feel, since a taller mattress sits closer to how a real bed clears the floor; nothing about actual comfort, firmness, leak resistance, or durability has been tested by this site, so this recommendation is built on the inflated-height number alone, not a comfort judgment.

Queen offers all three King Koil heights: 13" at $129.95 (compare-at $149.95), 16" at $139.95 (compare-at $159.95), and 20" at $149.95 (compare-at $169.95) — a twenty-dollar spread from shortest to tallest, stepping up by exactly ten dollars at a time. The 20" is the guest-bed pick here because it is the tallest option King Koil sells at this size. The 16" is the value pick: ten dollars less than the 20", taller than the 13", and the height King Koil itself uses as this product's recorded price point.

For a single overnight guest, Full is one size down from Queen and follows the same three-height pattern: $119.95 (13"), $129.95 (16"), $139.95 (20") — its 20" costs exactly what Queen's 16" costs, so a solo guest can get Full at its tallest height for the same money as Queen at its middle height. For two guests who want more room than Queen, California King runs $159.95 (13"), $169.95 (16"), $179.95 (20") — its price is thirty dollars above Queen's at every one of the three matching heights, the largest and most expensive option in the lineup.

All of these prices are the merchant's sale prices recorded on 2026-09-07, each listed next to its own struck-through compare-at price; they can change after that date. Shared terms apply to all three sizes, per the merchant rather than independently confirmed by this site: a 1-year warranty, 30-day returns, 2-3 business day shipping, and a built-in 120V/210W pump.

Who this is NOT for: guests on a strict budget, where Full at 16" ($129.95) or 13" ($119.95) undercuts every Queen height here, just with less sleeping surface. It is also not for anyone who wants proof that a taller mattress actually sleeps better, or is more comfortable, firm, leak-resistant, or durable — height here is a floor-clearance number from the merchant's spec sheet, not a comfort claim this site is making. And it is not for anyone comparing against a non-King-Koil guest mattress — this catalog has one brand to offer.
