Why consider it
Sealy
Sealy Mellbreak Ortho Plus Mattress
A firm traditional sprung mattress using Sealy's PostureTech support system and reinforced edges. It is scored most strongly for back/front sleepers, firmer preferences and edge support, with more conservative pressure-relief and motion-isolation scores.
- Firm PostureTech support
- Reinforced edge construction
- Double-sided design
- Good value in the traditional sprung category
Silentnight
Silentnight Ortho Dream Star Miracoil Mattress
One of Silentnight's firmest mattresses, built around Miracoil springs and Eco Comfort Fibre. It scores highly for firm-feel shoppers, back/front sleeping and value, but its extra-firm character makes it a weaker fit for side sleepers seeking deep pressure relief.
- Extra-firm support
- Miracoil no-roll-together design
- Reinforced edge support
- Strong value at its current from-price
