Comfort Exactly how you want it
The BreatheTech hyper soft bamboo knitted cover together with specially manufactured Antigravity Surface Foam ensures the ultimate softness without impeding sleeper moveability (compared to memory foam for example), and coolness.

Get the Firmness just the way you like it at home.
A split firmness system to suit each individual sleeper. Get it perfect at home, without any pressure.
Not just foam. Real Steel Springs for Proper Back and Body Support.
This mattress is setup to ensure the ultimate body support. A layer of adjustable variable firmness foams together with a perfectly calibrated twice tempered steel multizone pocket spring system ensures that the support is rock solid, and directed to the right parts of your body in just the right amount.

More Functional Space on the Bed thanks to Perimeter Springs
A Perimeter Zone of high strength Twice Tempered Steel Springs ensures that you can sleep right up to the edge, without collapsing it and rolling off (as often occurs with foam only mattresses which lack spring support). This provides up to 20 percent extra functional space on the top of the mattress, and makes ‘the Queen size mattress feel like a King’.

Refreshable Cover and Foamsso you can keep it like new.
Designed so you can keep it like new. The BreatheTech™ Cover is built and tested to resist pilling so you can Machine Wash it as often as you like - you can even replace it with a new one whenever you want.
Even the foam can be removed and vacuumed, or eventually replaced if you prefer. The high quality springs, which are built to last, mean this is possible even several years down the track.

A mattress that sags after a year or two of use can be seriously detrimental to your body
This is why the Mach II is built with Indestruct twice tempered steel springs to overcome the shortcomings of a foam only mattress. The two layers of foam that rest on top of the springs are 100% high-density AirGrown foams, which are incredibly sag-resistant. And just to be sure, we tested it with 8 years of simulated heavy usage.
There's no doubt about it. This mattress is built to last.
