Very Firm Mattresses

What are the benefits of an extra firm mattress?

75% of UK bad sleepers are woken by pain or discomfort. Due to their high level of support, very firm mattresses offer several benefits, including:

• Better spinal alignment - Very firm mattresses provide the most support for your spine, helping to alleviate back pain and improve posture.
• Reduced pressure points - Mattresses in extra firm comfort grades provide consistent support for the hips and shoulders.
• Enhanced durability - Due to their harder feel, very firm mattresses are less likely to sag over time and have minimal bounce, ensuring long-lasting comfort.
• Great for distributing weight - Ideal for heavier individuals, such as those over 14 stone, extra firm mattresses give you that extra support while distributing weight evenly to prevent you sinking into the mattress.

Will a very firm mattress suit my sleeping position?

An extra firm mattress is best for back and stomach sleepers, as it provides adequate support for your lower back and keeps the spine in the correct position while preventing the body from sinking too deeply. If you’re a side sleeper or you change positions during the night, or if you’re lighter than 14 stone, you’ll need more cushioning around the shoulder and hips, so a medium-firm or soft mattress may be better for you. For help, we offer a wide range of mattresses for your sleeping position.
