Adjustable Firmness Mattress: What They Are and What to Look For

An adjustable firmness mattress is a mattress that allows sleepers to change the feel of the bed after purchase rather than choosing a single firmness level that remains fixed over time. Unlike traditional mattresses that are manufactured with one firmness level, an adjustable firmness mattress typically offers a range of settings that can be adjusted to match personal preferences.

If you're exploring adjustable firmness options, understanding how they work and what features to evaluate can help you make a more informed decision.

What Is an Adjustable Firmness Mattress? (The Short Answer)

An adjustable firmness mattress lets a sleeper change the mattress's firmness after purchase, often through an internal air-based system rather than a fixed foam construction.

•  An Adjustable Bed Changes Firmness on Demand: With an adjustable firmness mattress, sleepers can typically increase or decrease the mattress's firmness level whenever they choose. Depending on the model, adjustments may be made through a remote, app, or integrated controls.

• How This Differs From a Traditional Mattress: Traditional mattresses are manufactured with a specific firmness profile and generally maintain that feel throughout their lifespan. If a sleeper wants a different firmness level, replacing the mattress is often the only option.

• Why Sleepers Choose Adjustable Firmness: People may consider an adjustable firmness mattress for a variety of reasons, including changing comfort preferences over time, different firmness preferences between sleeping partners, or the ability to fine-tune how the mattress feels from night to night.
