Finding the perfect pocket sprung mattress for heavy person in the UK isn’t just about picking the “firmest” option on the shelf. If you weigh over 100kg (approx. 16 stone), a standard mattress can lose its structural integrity within months, leading to the dreaded “middle sag.”
To get a restorative night’s sleep, you need a heavy duty pocket sprung mattress specifically engineered with thicker steel and reinforced boundaries. In this guide, we reveal the top-tested models available at Dreams and Bensons for Beds that actually hold their shape.
Why the “Spring Gauge” is More Important Than Spring Count
Most UK blogs tell you to look for a high spring count (e.g., 2000+). However, for a pocket sprung mattress for heavy person, the Spring Gauge (the thickness of the wire) is the real hero.
- Standard Gauge (1.2mm – 1.4mm): Likely to bottom out under 100kg+.
- Heavy Duty Gauge (1.6mm – 1.9mm): Essential for longevity and consistent spinal alignment.
Another “must-have” is reinforced edge support. For sleepers over 100kg, sitting on the edge of the bed to get dressed can permanently damage the border. A high-quality reinforced edge mattress UK ensures you can use 100% of the sleeping surface without feeling like you are sliding off.

Specialist Advice: Split Tension for Couples
If you weigh 110kg and your partner weighs 60kg, a “Firm” mattress might be perfect for you, but like a brick floor for them. Look for Split Tension options at Dreams or Bensons. This allows one half of the mattress to be “Extra Firm” and the other “Medium,” ensuring both partners get the correct pocket sprung mattress for heavy person support without compromise.
Final Verdict: Which should you choose?
- If you are on a budget: Go for the Dream Team Amersham. It offers incredible value for a true ortho feel.
- If you sleep hot: The TheraPur ActiGel 3800 is the gold standard for temperature control.
- If you want durability (10+ years): Invest in the Staples & Co Artisan—natural fillings settle better over time than synthetic foams under weight.
