Product details

Sometimes you just need a mattress that does the job — no extras, no drama. The Zinus Innerspring Mattress is built with a tempered steel Bonnell coil system for steady, dependable support. It’s a great fit for bunk beds, day beds, or anywhere a single-size mattress needs to slide in and hold up. There’s a light layer of foam on top, just enough to take the edge off, plus a quilted cover that feels soft to the touch. It’s lightweight, easy to move around, and a solid option for kids, guests, or even a quick nap spot in the study. Nothing complicated — just a good, springy mattress that gets it done. Single size only. Mattress only — frame sold separately. 5-year warranty included.

To help you find the perfect feel, it's important to know that firmness is relative. The feel of a mattress depends on your body weight.
A Simple Rule of Thumb:
- Sleepers under 80kg: May find that this mattress feels firmer than the rating.
- Sleepers 80kg and over: May find that this mattress feels softer than the rating.
Our Recommendation for Durability:
To ensure long-lasting support and prevent sagging, we strongly recommend a mattress of 30cm or thicker for any sleeper 80kg or over, or for couples.

It all depends on you! If you like a soft, cushy feel then memory foam is a good choice. For firmer support, a spring mattress works best. Hybrid mattresses—combination springs and foam—give you the best of both worlds. It's an important decision, so we wrote a whole article about it for our blog. Find out how to choose.
