Full returns policy →Semi-Orthopaedic Mattress — Made in Britain
The Apol Semi-Ortho sits between standard and full orthopaedic specification — firmer than a medium mattress but not as rigid as a full orthopaedic. Made in Britain to order. The right specification for sleepers who find standard mattresses insufficiently supportive but find full orthopaedic mattresses too hard — the middle ground that suits a large proportion of back and combination sleepers.
Key Features
- Semi-orthopaedic medium-firm specification — between standard and full orthopaedic
- Sprung construction — reliable, durable support
- UK-made to order — British manufacturing, 1–2 week lead time
- Available from Single to Super King
- Recommended for back sleepers and those with mild back discomfort
- Free UK delivery
Who Needs Semi-Orthopaedic?
Many people find that a standard medium mattress doesn't provide quite enough resistance for their back, but a full orthopaedic mattress feels uncomfortably hard. Semi-orthopaedic specification is engineered for this middle group — firm enough to prevent the lower back sinking into misalignment during sleep, but with enough give to be comfortable for side sleepers and those without acute back conditions. Often the first step up when a GP or physiotherapist advises a firmer sleeping surface.

What is the warranty? 1-year manufacturer warranty. Rotate head-to-toe monthly during the first year for even wear.
How do I care for this mattress? Rotate head-to-toe monthly. Use a mattress protector. Do not fold or bend when handling.
Should I choose Semi-Ortho or full Orthopaedic? If you wake with back pain on a medium mattress, start with the Semi-Ortho — it provides meaningful additional support without the full firmness of an orthopaedic. Only step up to full orthopaedic if the semi-ortho still feels insufficiently firm after a settling-in period.
