Mattresses for adjustable bed bases

In the pursuit of a restful night’s sleep, many turn to adjustable bed bases for their ability to address several needs—ranging from medical conditions to specific comfort requirements. Whether seeking relief from ailments, enhancing overall comfort, or facilitating easier access in and out of bed, the right combination of an adjustable bed base and a suitable mattress is paramount.

Adjustable beds are designed with mechanisms that allow users to customize the positioning of the head and foot sections of the bed. This adaptability is particularly beneficial for individuals with conditions such as sleep apnea, acid reflux, or chronic pain. Moreover, adjustable beds cater to personal comfort preferences by providing various ergonomic positions, potentially improving circulation and reducing pressure on certain body parts.

In this guide, we delve into the intricacies of selecting mattresses that not only complement the versatility of adjustable beds but also cater to the unique demands arising from personal comfort preferences and the desire for enhanced accessibility.

Can any mattress be used on an adjustable bed base?

No, not every mattress is suitable for use on an adjustable bed. Adjustable beds require mattresses that can flex and bend without losing their structural integrity. Traditional innerspring mattresses, for example, may not be compatible as their rigid design can be damaged when the bed is adjusted. Instead, mattresses specifically designed for adjustable beds are recommended. These types of mattresses better conform to the bed’s movements. Therefore, it’s crucial to choose the right mattress to ensure optimal performance.

Can I use a memory foam mattress on an adjustable bed base?

Absolutely. Based on our experience, foam mattresses significantly surpass their sprung counterparts when paired with adjustable bed bases. The flexibility of memory foam, in contrast to the rigidity of metal springs, enables a more seamless and accommodating bend, better adapting to the contours of the bed and elevating your overall sleep experience.

How thick should a mattress be for an adjustable bed?

Yes, indeed. To ensure optimal performance and flexibility, we recommend choosing a mattress with a maximum thickness of 18cm. This is a fairly common depth for the majority of adjustable beds, and adhering to this guideline allows the mattress to flex and bend with an adjustable bed base, maximising both comfort and functionality.

What mattress firmness rating is best for an adjustable bed?

The key to a harmonious partnership between your mattress and adjustable bed lies in finding the right firmness. Generally, medium or medium/firm mattresses are the top choices for adjustable beds.

The softer the mattress, the more it can bend and adapt to the bed’s movements. While firmer options are available, consider they may limit the mattress’s range of motion, reducing compatibility.

How much will the mattress bend on an adjustable bed?

Predicting the exact degree of mattress bend is a complex task. The variability among different adjustable bed manufacturers and their mechanisms, coupled with the diverse characteristics of mattresses, makes it challenging to provide a one-size-fits-all answer.

The flexibility of your adjustable bed will depend on a combination of factors, so it’s best to consult with the bed base manufacturer to ensure compatibility.


In the world of adjustable beds, detail matters. To maximise the potential of your adjustable bed base, it’s imperative to choose a mattress with a depth not exceeding 18cm. This ensures that your mattress best adapts to the contours of the bed, providing you with the flexibility and comfort you desire.

Remember, when it comes to adjustable beds, the right mattress is the key to unlocking the full range of motion and comfort.
