Thinking About Which Comfort Level You Need
Firm Mattresses

If you want a firm mattress, a Restonic king-size mattress might be a good choice for you. These firm mattresses encourage circulation and blood flow, aiding in deeper sleep. They deliver proper weight distribution, which comfortably prevents pressure by balancing your body without having your back or joints sink. They are ideal for back sleepers and are designed with a 34-36 pound indentation load deflection ranking. One downside is that they may be uncomfortable if you're not accustomed to sleeping on hard surfaces, so it can take a few days to get used to them. On top of that, they can put strain on specific pressure points, so if you want a mattress that relieves pain in pressure points, this is not the mattress for you.

Extra Firm Mattresses

Looking for a good extra firm mattress? Consider a Restonic king-size mattress. Extra firm mattresses deliver proper weight distribution to support your back and joints and other sensitive areas. They encourage circulation and blood flow, so they promote deeper sleep. They are perfect for back sleepers and have a 39-42 pound indentation load deflection ranking.

On top of that, they can be uncomfortable if you're not accustomed to sleeping on hard surfaces, so it can take a couple of days to get used to them.

Medium Firm Mattresses

Looking for a good medium firm mattress? Consider a Restonic king-size mattress. These mattresses provide proper weight distribution, supporting your back as well as other vulnerable areas.

They are a win-win situation, catering to couples that have one individual who enjoys to sleep on their side and the other on their back or stomach.
