Healthopaedic Billionaire Ortho Mattress

If you're a preferred back sleeper or you're of a larger weight group, a firmer mattress is better designed for you. For those with larger statures, your weight will be evenly distributed across a firmer mattress which will help you wake up feeling like you've been properly supported. If you prefer to sleep on your back then this will ensure that your lower back receives the support it needs to promote healthy spinal alignment.

Probably not. Although much of it is also down to preference, a firmer mattress will be too firm for side sleepers and cause the spine to rest in an unnatural position. This means you can wake up feeling pain in your back due to improper spinal alignment. The same premise applies to people of a light stature, as a softer mattress is suitable to support your body weight properly.
