People over 100 kg should choose a firmer mattress to prevent severe back, neck, and spine problems.
We’d recommend a firm mattress in the H4 range (Sleep Hero 8).
For people over 140 kg, an H5 mattress may be more appropriate (Sleep Hero 9 - 10).
A barrel pocket spring mattress is also a good choice, as it adapts well to the body and relieves pressure well.
