Frequently Asked Questions

Enjoy Solid Support with a Firm Mattress

With less give under pressure than softer mattresses, a firm mattress provides a solid foundation for a good night’s sleep.

Unlike plush mattresses that use additional comfort layers for a cushioned sensation, firm mattresses rely on high-density foam or latex, high-gauge springs and robust support systems to create an ultra-stable surface and prevent the body from sinking.

Why Choose a Firm Mattress?

Sag-resistant and durable, firm mattresses promote even weight distribution and help to maintain correct spinal alignment for peaceful, pain-free sleep. As a result, they’re often recommended for back sleepers, heavy individuals and those with lower back pain.

However, comfort preferences are personal, and other sleepers may simply prefer the feeling of a firm, non-yielding mattress.

The Ecosa Mattress: An Adjustable Firm Mattress in a Box

Looking for a firm mattress in a box? Enjoy free next-day metro delivery with the bestselling Ecosa Mattress. In durable ergonomic foam, our adjustable firmness mattress is engineered for spinal support and relief from back pain.

With three comfort settings – medium, medium-firm and firm – it’s easy to adjust the firmness level at home as often as you like.

Our Affordable, Eco-Friendly Essence Firm Mattress

Also available in plush and medium, our Essence Mattress is a quality, budget-friendly firm mattress. With five zones of high-gauge, zero-waste springs and eco-friendly materials including Bio Foam, it’s also gentle on the planet.
