If you run hot at night, the Zinus Cooling Essential Foam Mattress might be exactly what you’ve been missing. It’s made with cooling layers that help pull heat away while you sleep, so you’re not waking up sticky or uncomfortable. Underneath, high-density foam gives you the right balance of support and pressure relief — firm enough to feel stable, soft enough to stay comfortable. It shows up compressed in a box (easy win), and sets up in minutes — no stress, no heavy lifting. Simple, breathable, and surprisingly comfy for a foam mattress at this level. Available in Single, and King Single size.
