Who needs a Bonnell spring mattress? The answer is someone who wants a relatively firm and comfortable sleeping surface. And that is what you get with our Giselle Beddings Glay Series Bonnell Spring Mattress. The Bonnell spring system uses springs that are hourglass shaped to provide better support for your body, more resilience and better ventilation. Our mattress delivers all of the above with a level of comfort that surpasses expectations and a medium firmness that many Australians desire. The mattress is meticulously constructed with layers of premium materials. High-density foam fills the inside of the mattress in between the stable Bonnell spring core and a soft quilting layer rests on top. Essentially, you get a solid mattress that retains its shape well for long-lasting use, while still being supple and comfortable for you to enjoy all its inherent benefits. So, indulge in a mattress that knows your sleep well. Befriend a Giselle Beddings mattress today.
