The Cooper Polyfoam Mattress

The zipper system

Just like the Sienna and Aurora, it has a modular zip system. You can purchase any “firmness number” Cooper mattress and we can adjust it to any other “firmness number”, (or any other ausbeds mattress of the same size) post-purchase. Still don’t like it? Get a refund really quick.

How is it different from the other ausbeds mattresses?

The only difference is in the 7.5cm comfort layer (the foam padding or polyfoam). The outer cover and the spring unit are exactly the same as the Aurora and Sienna. The cooper doesn’t have latex in it. It uses the same foam as 99% of mattresses on the market. We still use high-density foam for the comfort layer so there should be no issues with dipping.

Is it comfy?

Much of ausbeds mattresses’ comfort comes from the springs. Understanding that much of the comfort comes from getting the customer’s body weight adjusted to the spring is key here. And that’s exactly what we do at ausbeds. If it’s not the right spring, we can change the whole spring. It takes 5 mins.

What if it dips?

Like any mattress at ausbeds, all parts are replaceable. If it dips, we’ll easily be able to replace the layer rather than throw the whole thing away. We look at these layers much like a bicycle tire, if it wears out, replace it, no need to throw the whole bike away.

How do you change the mattress?

Each mattress is made up of components, we can easily drive out with the component and change it. This process usually takes no longer than 3 minutes. 

Is it difficult to change the mattress?

It’s really easy! We built the ausbeds factory from the ground up to solve this exact problem.

What if it still doesn’t feel right?

There are 3 firmness options in each mattress, if that doesn’t work, we can drive out and change your mattress to any of our 22 mattresses, or do a refund (refund information page).

How long is the warranty?

0 to 100 days – We can provide as many adjustments as you like in that time. If you still aren’t happy, you can get a refund if you don’t like it 🙂 and we’ll personally pick it up.

100 days to 10 years – You can call our factory anytime, and we will be there to help troubleshoot any issues that may arise, and we can replace any layer at all in the mattress.
