Do Adjustable Beds Need Special Mattresses?

Your new adjustable bed is a piece of technology with excellent benefits for your sleep quality and overall health. However, purchasing one of these devices can be very expensive compared to standard beds and even more costly when considering you’ll probably need a new mattress.
Adjustable beds switch positions constantly. If your mattress doesn’t have good flexibility, it will not allow the mechanism to move. In other words, without the ideal mattress, you won’t enjoy the perks of your adjustable bed.
These are the best mattresses for your adjustable bed:
Why Do Mattresses Slide On Adjustable Beds?
There can be multiple reasons why your mattress slides when you use your adjustable bed. In most cases, the problem is the mattress itself. Sometimes it can be too big or might not have enough friction to remain steady.
Here are the main reasons why mattresses slide on adjustable beds:
How to Keep Mattresses From Sliding On an Adjustable Bed?
There are different ways to prevent your mattress from sliding off when adjusting the position of your bed. The ideal option is purchasing the correct sized mattress, but there are other things you can try.
Getting the Right Size Mattress
Adjustable beds need different mattresses than regular beds. When the bed switches positions, the mattress needs the flexibility to adjust. However, that's not everything a mattress needs.
It needs to be the right size. If not, it will slide off whenever the bed inclines in one direction. Usually, you can get good deals when buying adjustable bed packs, including the correct mattress and bedding for the bed dimensions.
However, if you prefer to buy accessories separately, you’ll need to pay attention to the bed’s measurements. Twin-size frames need twin-size mattresses, and the same goes for California king models.
Placing the Mattress Retainers Properly
Adjustable bed manufacturers understand that keeping the mattress from sliding is essential for a good customer experience. So, many of these companies have added holders to the headrest and footrest at the base to prevent any slipping. The mattress holder is simply a steel bar you can attach to one side of the bed.
Here’s what you need to do to install the retainers:
- 1Firstly, locate the mattress holder bar and its bushings.
- 2You’ll notice two holes in the base. Place the bushings in the holes by pressing them as firmly as possible.
- 3Once the bushings are in, you can attach the mattress retainer bar.
- 4Test your bed with the mattress before using it to sleep.
If the retainer bar does not help prevent sliding, you will need to consider buying a new mattress or the next option.
Buying an Anti-Slip Pad
One more option you have is to simply buy an anti-slip pad and place it in between your mattress and the adjustable base. This pad will adhere to your mattress, creating the necessary friction to prevent unwanted movement.
The only drawback of this option is that these accessories are not always easy to find and can be rather expensive.
Here are some other options if you prefer not to buy an anti-slip pad:
Tip: Some mattresses include anti-slip surfaces you can place on your adjustable bed. You only need to put the right side facing the base. They tend to be more expensive, but they are also extremely helpful.
How to Buy the Right Mattress for Your Adjustable Bed

Now that you have your new adjustable bed, it is time to turn your attention to getting the right mattress for it.
Here are the characteristics to consider when buying a mattress for an adjustable bed:
Note: Picking the right mattress for your adjustable bed is as important as the adjustable frame itself. If the mattress is uncomfortable, it doesn’t matter which position you use. You won’t find the sleep quality you’ve been looking for.
Conclusion
Finding the right mattress for your adjustable bed can be challenging, but it is essential if you want to prevent sliding. Ideally, you should find a flexible mattress with the right dimensions for your bed. However, you shouldn’t compromise on lumbar support or comfort.
If your mattress slides even with the right size, you can try installing the retainer bar on one side of the bed. It should prevent any unwanted movement. If it is still not enough, you can try placing a pad between the mattress and the base to create friction.
