1. What is the firmness of the Sleep Firm?
The Sleep Firm Mattress features an exceptionally firm surface tailored for back and stomach sleepers needing rigid posture support.
Because of its lack of give, it is not ideal for exclusive side sleepers unless they specifically want a very hard bed. The brand offers a 150-night trial to let you test the firmness risk-free.
2. Does the mattress require flipping or rotating?
The Sleep Firm Mattress is a single-sided, layered construction, meaning it should never be flipped upside down. However, to ensure even wear over its lifespan, it should be rotated 180 degrees (swapping the head and foot ends) every two weeks for the first three months, and once every three months thereafter.
3. What type of bed base or frame is recommended?
To preserve the structural integrity and validation of the mattress warranty, it must be supported by a flat, rigid, and well-ventilated surface. Recommended bases include:
- Solid timber or steel platform bases.
- Specially designed ensemble bases.
- Slatted bed frames, provided the gaps between the slats do not exceed 7–8 cm. Flexible sprung slats are generally not recommended as they can alter the intended extra-firm feel.
