Tanzanite Sleep Mattress
Price range: £159.99 through £389.99
A medium-firm mattress that works as hard as you do.
The Royal Ortho Open Coil Mattress – Medium Firmness is built around one principle: give your body the support it actually needs, without the unforgiving rigidity of a full orthopaedic feel. The result is a mattress that sits right in the sweet spot, firm enough to keep your spine aligned, comfortable enough to wake up without that familiar ache in your lower back.
Support that comes from the construction, not just the marketing.
Open coil spring systems have been the foundation of quality British mattresses for decades, and for good reason. The interconnected coil network in the Royal Ortho distributes your body weight evenly across the entire surface, with no sagging under the hips, no unsupported gaps at the shoulders. If you’ve been waking up stiff, the issue is often a mattress that’s stopped pushing back. This one does.
What’s inside:
- Open coil spring system, consistent, full-surface support
- Medium firmness rating, suitable for back, side, and combination sleepers
- Hand-tufted Damask fabric cover, durable, breathable, built to last
- Even weight distribution reduces pressure on joints and the lower back
- Traditional orthopaedic construction, spinal alignment from the ground up
Who it’s for.
This mattress suits anyone who wants reliable support without a rock-hard feel. It’s a strong choice for back sleepers and combination sleepers who shift position through the night, and for anyone who’s been on a soft mattress that’s lost its shape, leaving them sleeping in a dip. It also pairs well with any of Style Beds’ upholstered bed frames, particularly with ottoman or divan bases, where a medium-firm mattress complements the solid base structure.

Frequently Asked Questions (FAQ’s)
Medium-firm is widely considered the most back-friendly firmness level. The Royal Ortho’s open coil construction supports spinal alignment and reduces pressure on the lumbar region, making it a practical choice if lower back discomfort is a concern.
Open coil springs are interconnected, meaning the entire spring network responds as a single unit, providing even, consistent support across the entire surface. Pocket springs move independently, which is better for motion isolation between two people—open coil suits solo sleepers or couples who prefer a firmer, more responsive feel.
Yes. The Royal Ortho works on slatted bed frames, divan bases, and ottoman storage bases. For best results and to protect your warranty, use slats no more than 7cm apart.
The Royal Ortho is delivered flat, not rolled. This preserves the integrity of the open-coil system, ensuring it’s ready to use from day one.
