How do different material mattresses require varing thickness level?

Different mattress materials have different requirements for thickness:
Spring mattress: Spring mattresses need a certain thickness to provide support and resilience. Thicker spring mattresses generally provide better support, but may not be as comfortable as thinner spring mattresses.
Memory foam mattress: Memory foam mattresses can mold to your body shape, so they don't need to be too thick to provide good support and comfort. Thicker memory foam mattresses may be more comfortable, but they will also be more expensive.
Latex mattress: Latex mattresses have good elasticity and breathability, so they don't need to be too thick to provide good support and comfort. Thicker latex mattresses may be more durable, but they will also be more expensive.
Foam mattress: The thickness of foam mattresses can vary greatly. Thicker foam mattresses may provide better support and comfort, but they will also be more expensive.
