Pocket Spring Mattress · Cooling Cover · Foam-Encased Edges

The Sleep Zen is a very firm pocket spring mattress with a cool-touch cooling cover and foam-encased edge support. Its white cooling cover has a cool-to-the-touch feel, while the spring core is wrapped on every side in high-density foam, so the edges stay firm and you can use the full surface of the bed. With a very firm 8.5/10 feel and a 29 cm profile, it's a substantial, supportive mattress.

Cool-touch cooling cover

A white ice-silk cover with a cool-to-the-touch surface.

Foam-encased edges

7 cm of high-density foam surrounds the spring core for sturdy edges and full-surface use.

Very firm support

Firmer pocket springs and a high-density foam layer for firm, stable support.

Foam-encased edge support

Around the pocket spring core, the Sleep Zen builds a 7 cm border of high-density foam on all four sides. That foam frame keeps the perimeter firm, so there's no roll-off when you sit on the side or sleep near the edge, and the full width of the mattress stays usable. Inside the frame, firmer 2.4 mm pocket springs deliver the mattress's very firm support.

Frequently asked questions

How firm is the Sleep Zen, and who is it for?

It has a very firm feel — around 8.5 on a 1 to 10 scale — built on firmer pocket springs and a high-density foam layer. That suits sleepers who prefer a firm, well-supported surface. Firmness is subjective, so we'd suggest trying it in person at one of our five SE QLD showrooms.

What is the cooling cover?

The Sleep Zen is finished in a white ice-silk fabric that has a cool, smooth feel against the skin, so the surface feels cooler to the touch when you first lie down.

What does foam-encased edge support mean?

The pocket spring core is surrounded on every side by 7 cm of high-density foam. This reinforces the perimeter, so the edges stay firm when you sit on the side or sleep close to the edge, and it helps you use the full surface of the mattress.

Is it a good choice if I share the bed?

Yes. Because each pocket spring is individually wrapped and works on its own, the springs respond mainly under each sleeper, which helps keep one person's movement from carrying across to the other side.

How is the Sleep Zen delivered?

It's delivered as a full-size, uncompressed mattress — not rolled or boxed — so it's ready to use once it's on your base.

What sizes does it come in?

Queen and King — dimensions are listed in the Dimensions & sizes section above.

What base or frame should I use, and do I flip it?

Use it on a solid (platform) base or a slatted base with evenly spaced slats, so it's supported evenly across its full size — an unsupportive base can affect comfort and may affect your warranty (see our warranty policy). The Sleep Zen is single-sided, so don't flip it; rotate it head-to-foot every few months to help it wear evenly.
