Why choose a king mattress?
A king mattress with a high pocket spring count easily accommodates two sleepers while providing the utmost support. Paired with comfort layers like gel infused memory foam, you will get the best night's sleep possible.
Whether you're sleeping alone, or with a partner, a king mattress in a box gives you plenty of space to stretch out without worrying about your toes getting cold. At Sleep Republic, we've experimented for years on how to combine pocket springs and memory foam in one mattress. We're happy to say we've found the perfect outcome. 2250 pocket springs, plus memory foam, and other comfort layers — and we can fit it all in a box for easy delivery.
As long as you're located within the range of our partnered delivery companies, we can get your king size hybrid mattress in a box to you within a few days. We've worked for years to find the best delivery companies to deliver to locations all over Australia.
