Perhaps you just bought an adjustable base and are looking for the right mattress to go with it. Maybe you are looking to upgrade the existing mattress that came with your base. Whatever the case, you’ve come to the right place.

Choosing a mattress for an adjustable bed is trickier than a regular mattress. You see, not all mattresses are compatible with adjustable beds. The right mattress should not only match your support and firmness needs, but also seamlessly bend with the movement of the adjustable bed.

Usually, all flexible mattresses are compatible with adjustable beds, but some might be better than others. In our experience, latex, memory foam, and some pocket coil mattresses pair up well with adjustable beds, while innerspring mattresses are simply just a no-no.

In this guide, we will try to educate you on what factors you should consider while buying an adjustable bed. We will also introduce you to our top 5 mattress picks for adjustable beds available in the Australian market today.

Few points to keep in mind:

1) Not all mattresses are compatible with adjustable bed.

Though you don’t need any special type of mattress for an adjustable bed, you do need the mattress to be flexible enough to match the movement of the base. The ideal mattress should be pliable and not be too thick (15″+).

Innerspring mattresses are almost certain to not be compatible with adjustable bases. The coils in innerspring mattresses make them too rigid, and they can’t bend with the movement of the bed. Generally, memory foam, latex, polyfoam, and hybrid mattresses are compatible with adjustable bases. But it’s always a good idea to check with the manufacturers before you make your final decision.

2) Always choose a mattress that offers a sleep trial.

When it comes to adjustable beds, no matter how good the quality of the mattress is, there is no guarantee that it will be compatible with the base. That’s why we always recommend choosing a mattress that comes with a sleep trial. This way, you won’t be stuck with a mattress you don’t like, and can return it if it’s not a good fit.

How did we pick?

Our first and most obvious criteria were whether the mattress is compatible with adjustable bases, significantly narrowing our options. Next, we only included mattresses with a sleep trial or exceptional positive customer reviews, leaving us with 12 options.

Our team then tested each of the selected mattress options on the Peacelily adjustable base, checking for the adaptability of the mattress with base, the support offered, edge support, motion isolation, and overall comfort.

We then considered the brand’s reputation, warranty and price to arrive at our final five picks.

Our top picks:

1. Onebed X 12″ Mattress – Editor’s Pick


The well-rounded characteristics with a good balance of comfort and support, high-quality pocket coil construction and competitive pricing put the Onebed X mattress as our top choice. The mattress is supportive yet flexible enough to be used with adjustable bases, which is not always the case with hybrid mattresses.

The mattress boasts a hybrid design with a supportive 5-zoned pocket spring core and pressure-relieving memory foam layers topped with breathable Davina foam. The Onebed X has a medium-firm feel that should accommodate most types of people. Sleeping on the mattress, you experience decent body contouring, while the zoned coil core offers targeted support.

We also feel the Onebed X 12″ is an excellent choice for plus size sleepers because of its strong individually wrapped coils. Sleepers looking for pain relief may also do well on the mattress due to the memory foam’s ability to reduce pressure points.

What Makes Onebed X Stand Out?

  • It’s a great pick for hot sleepers.
  • High quality and durable construction.
  • Decent motion isolation and excellent edge support make it a good option for couples.
  • The bed comes with a generous 125-night sleep trial.


  • Individuals after a plush mattress.
  • People who like the hug of a pure memory foam mattress.

2. Peacelily Latex Mattress Best Latex (100% organic)


The Peacelily latex mattress is an all-natural mattress that eco-conscious buyers or fans of latex mattresses may appreciate. Surprisingly, the mattress is quite affordable for an all latex construction. Made with multiple layers of Dunlop latex and covered in an organic cotton cover, the mattress is responsive and highly supportive.

The unique feature of the mattress is that it’s dual-sided. You can choose between the medium or the firm side based on your preference.

Characteristic of latex mattresses, the Peaceily mattress is extremely breathable and promotes airflow. Even the hottest of sleepers should sleep comfortably on the mattress. The mattress is durable too – no wonder the brand offers a 25-year warranty on the mattress!

The mattress has a buoyant and responsive feel, and you tend to sleep more “on” than “in” the mattress. You don’t get much contouring, or a cradled feeling from the mattress, but rather, there is a generalised sinkage around the whole body.

Sleeping on the mattress, you can expect an exceptional amount of pressure relief around the shoulder and hip region. The latex construction also makes the mattress very supportive and a good pick for heavier folks.

What Makes Peacelily Stand Out?

  • Those looking for a durable mattress and a long term investment.
  • The mattress is a great choice for hot sleepers.
  • Those after a responsive and supportive mattress.
  • People looking for an organic mattress.
  • Individuals unsure of their firmness preferences – it’s a dual firmness mattress.


  • Those who prefer the hug of memory foam.

3. Ergoflex 5G Mattress – Best Memory Foam


Medical Disclaimer: Please consult your GP for any specific medical advice. Consider the following information for educational purposes only.

When it comes to pain relief, be it back, shoulder or hip, you need a mattress close to a medium or medium-firm that supports your spine in a neutral alignment. Memory foam is often the preferred option for sleepers looking to alleviate back pain as it contours and molds to your body shape, and prevents pressure point formation.

The Ergoflex 5G is a PURE memory foam mattress and could tick all the right boxes for anyone looking for a mattress for pain relief. You can expect an ample amount of pressure relief and support from the mattress.

The mattress feels slightly firmer than medium (7/10) initially, but characteristic of memory foam mattresses, you slowly melt into the mattress and enjoy a good amount of sinkage and hug around the body.

That said, memory foam can be a love it or hate it material. Some sleepers find the quicksand feeling or hug too constricting, while many find it comforting. For a memory foam material that is often notorious for trapping too much heat, the Ergoflex 5G does a good job of regulating temperature. Being an all-foam bed, the mattress is compatible with all adjustable bases.

What Makes Ergoflex 5G Stand Out?

  • The mattress offers excellent pressure relief, deep contouring and support.
  • Helps maintain neutral spine alignment.
  • Quite affordably priced for a pure memory foam bed (like-for-like alternative to Tempur supreme, which costs 3x the price)
  • For a memory foam bed, it doesn’t trap too much heat.


  • Those who don’t like memory foam’s “hugging” feel may not find the mattress comfortable.
  • 30-day sleep trial, which is lower than the industry average.
  • Combination sleepers may find it challenging to switch positions on the bed.

4. Ecosa Mattress – Best For Changing Sleep Needs


If you’re unsure about what firmness you need, or find that your sleep needs change over time, the Ecosa mattress may be a good option. The Ecosa mattress can be adjusted to three firmness levels – medium (6), medium-firm (6.5) and firm (8) simply by flipping or changing the position of layers. The adjustable firmness makes it accommodating enough for a range of sleepers.

The mattress has a balanced foam feel that cushions the body, but you don’t get the sinking “in” feeling as you would with a memory foam mattress. You should expect good support in all configurations with an above-average bounce and pressure relief. Compared to all-foam beds, the Ecosa mattress sleeps cooler; however, it’s not as cool as latex or hybrid mattresses.

What Makes Ecosa Stand Out?

  • Its adjustability – you can customise the firmness level to better suit your needs.
  • The mattress is very versatile and suitable for a range of sleepers.
  • In-built mattress protector.
  • 15-year warranty.
  • Value-for-money pricing.


  • Heavier or plus sleepers may not be well catered to on the mattress.
  • Those after a plush soft mattress may not find it comfortable.

5. Emma Comfort Mattress – Best Affordable


Budget shoppers looking for a quality mattress for their adjustable base may consider the Emma Comfort mattress. It’s an all-foam bed with rather simple construction, and is fully compatible with adjustable bases. There is a 3″ thick proprietary Airgocell foam layer on top for pressure relief, followed by a 7″ thick high-density HRX zoned foam base for support.

The mattress feels approx. 7/10 on the firmness scale, making it slightly firmer than a medium-firm. The industry standard for medium-firm is 6.5/10, where 1 is the softest and 10 is the firmest. You sleep more “on” than “in” the mattress. There is a bit of sinkage around the body but nothing too substantial.

The mattress is supportive, and the zoned construction, which is firmer around the hip region and softer near the shoulder area, allows for extra pressure relief. The mattress performs quite well in the temperature regulation and motion isolation department.

The Emma Comfort mattress is a great affordable option if you’re looking for an adjustable bed-friendly mattress. It offers a well-rounded sleep experience with good support, pressure relief and temperature regulation.

What Makes Emma Comfort Mattress Stand Out?

  • The mattress offers excellent bang for your bucks.
  • The balanced feel should please most average weight back, side or stomach sleepers.
  • Good temperature regulation and motion isolation.


  • Not suitable for plus size sleepers.
  • Edge support is average.
  • It might feel too firm for petite sleepers.

Buying a mattress from the same manufacturer as the adjustable bed vs from a different one

Many adjustable bed manufacturers would suggest you buy their in-house mattress to go with the base. While this is partly true, there are both pros and cons to it. 

If you buy the mattress and the adjustable base from the same manufacturer, you can be certain that the mattress is compatible with the base. The mattress would match the size, and you should not face any mattress slipping issues, as both the units would have been extensively tested. The downside to this option is that you might have to compromise on your mattress preference, as the selection would be limited to the mattresses offered by that manufacturer.

On the other hand, buying from different manufacturers gives you more choice and flexibility. You can pick a mattress that better suits your needs. However, there is no guarantee that the mattress would cohesively work with your adjustable base, as both the units might not have been tested together.

If you’re going for a mattress other than the one offered by your adjustable base manufacturer, then our suggestion would be to stick to name brands and the ones that offer free sleep trials. Most of the big brands have standardised mattress sizes, and some of them will even mention if their mattress is compatible with an adjustable base or not.
