Can you put a hard board on the mattress?

Sleeping on a hard board is good for your health.

1, Support: Hard wood boards can provide extra support, which is good for people with back or joint problems.

2. Durability: hardwood boards are usually more durable than mattresses and do not need to be replaced frequently.

3, temperature regulation: hardwood can help regulate body temperature, because it does not absorb heat like a mattress.
