Zinus King Single Mattress Essential Bonnell Inner Spring

The 15cm Zinus Innerspring Comfort Mattress keeps things simple — in the best possible way. It’s built with a layer of foam on top for a little cushioning, and supported by a Bonnell continuous coil system underneath that keeps things steady and breathable. It’s a great match for lighter sleepers, bunk beds, or guest spaces where you don’t need a super thick mattress. It’s compact, easy to move, and gives you that classic springy feel without overcomplicating things. Available in Single, King Single, Double, and Queen. 5-year warranty included. Note on firmness rating: Mattress firmness ratings are a general guide, as how a bed feels depends on your body weight. Sleepers under 80kg sink in less, making mattresses feel slightly firmer, while anyone over 80kg presses deeper into the support layers for a softer feel. For couples, combined weight in shared areas means thinner mattresses compress more than they would under a single sleeper.
