King Single Pocket Spring Mattress Extra Firm 33cm | EXTG

If you're someone who genuinely loves the feel of a firm, supportive bed — not the marshmallow-soft kind — this 33cm pocket spring mattress is built with you in mind. It's rated 8.0 Extra Firm, which puts it squarely in the territory of traditional hard-bed lovers, back sleepers, and anyone dealing with back pain who needs proper spinal support night after night. The 7-zone ergonomic design means different parts of your body get the right amount of support in the right places, from your shoulders right down to your legs.

What really sets this one apart is the dual-row edge support — instead of the usual foam border that quickly loses its shape, there are two rows of hardened springs running along the long sides. That means you can sit on the edge to tie your shoes or sleep closer to the side without that annoying sensation of rolling off. The 3cm egg crate foam comfort layer also helps with airflow, so if you run warm at night, it's a much better option than a dense memory foam mattress. It arrives vacuum-packed and will expand to full shape within a day of unpacking — no assembly needed.

This is solid value for a quality King Single mattress, and it's backed by a 5-year warranty for extra peace of mind. You can find it right here at EXTG, and if you'd rather spread the cost, you can grab it on Afterpay too.
