King Single Mattress

Shop king single mattresses online - 107 x 203 cm, the growth-proof kids' size. Compared with a standard single it adds 15 cm of width and 15 cm of length, and that length matters: a king single is as long as a queen, so it comfortably carries a child from primary school through the teenage growth spurts without another upgrade.

It's also a smart pick for single adults who want more room than a single without a double's footprint - think studio apartments, spare rooms doing double duty, and taller teens. Check your room keeps a walkway beside the bed, and match the size exactly to a king single frame.

King single mattresses are delivered Australia-wide, eligible products carry at least a 12-month warranty, and 14-day returns apply. Compare the double if width matters more than length, and browse bed frames in matching sizes.
