Strong Support for Better Alignment
A firm mattress keeps your spine in a neutral position by preventing excess sink-in, especially around the hips and lower back. This can ease discomfort for some sleepers and is often recommended for those who suffer from back pain or require orthopaedic support.
It’s also a good match for front sleepers and heavier body types who benefit from extra resistance.
Types of Firm Mattresses Available
iSleep’s firm collection includes a mix of:
- High-density memory foam for contouring without sag
- Pocket sprung models for firm lift with natural airflow
- Hybrid styles that balance strong support with subtle pressure relief
These designs minimise sink-in and motion transfer, offering a consistent feel across the entire surface.
Durable Build, Easy Delivery
Each mattress is built using durable core materials, reinforced edges, and breathable outer covers. Many include washable zip-off layers to make upkeep simpler.

Frequently Asked Questions
Is a firm mattress too hard to sleep on?
Not necessarily. While firm mattresses offer strong support, modern materials add just enough cushioning to prevent discomfort. They’re designed to feel stable, not rigid.
Who should choose a firm mattress?
Firm mattresses are best for back sleepers, stomach sleepers, and heavier individuals. They help reduce pressure on the spine and prevent sinking into the bed.
Can a firm mattress help with back pain?
Yes. A firm mattress can assist with spinal alignment and relieve lower back strain, particularly for those with mild discomfort or posture-related issues.
Are all iSleep firm mattresses delivered rolled and boxed?
No, due to their structure, our hard mattresses like the Luxe Hybrid Pocket and Luxe Cooling Mattress models cannot be delivered rolled.
