More Air Is Not Always Better
Excessive pressure can put unnecessary stress on seams and internal structures. Comfort can also become worse when the surface is overly rigid.
Adjust For The Sleeper
A useful firmness level supports the sleeper without excessive sag. Make small changes and give the material time to settle.
Consider Temperature
Temperature changes can affect pressure, which is another reason not to inflate aggressively at one moment and assume the setting will never change.
Frequently Asked Questions
How Do I Know It Is Too Firm?
If the surface feels unnecessarily rigid or the product is beyond the manufacturer's intended inflation state, release a small amount of air.
Can Overinflation Cause Damage?
Excessive pressure can stress inflatable structures. Use the manufacturer's instructions rather than intentionally pushing beyond them.
