Medium Firm Feel and Who It Suits
A medium firm mattress rates around 6 on the firmness scale. It offers a balance of support and pressure relief. This feel suits back sleepers and combination sleepers. Side sleepers may need extra cushioning, while stomach sleepers might prefer firmer options.
Why Fiberglass-Free Matters
Fiberglass is sometimes used as a fire barrier in mattresses. It can become airborne if the cover is damaged. This can cause skin and respiratory irritation. Choosing a fiberglass-free mattress avoids these risks.
