Choose Flexibility With An Adjustable Firmness Mattress
What To Consider When Shopping For An Adjustable Firmness Mattress
For most sleepers, a mattress with customisable layers is ideal. However, a half-and-half configuration or air mattress may suit firmness-incompatible co-sleepers or those with specific health requirements.
Also consider the firmness range offered, as this will differ by model and brand.

Is An Adjustable Firmness Mattress Worth It?
Adjustable firmness mattresses, especially high-tech air mattresses, may be slightly more expensive. However, when you weigh the cost of sleeping on a hastily purchased mattress that’s too firm or soft, the in-built flexibility is well worth it.
