How to stop your top mattress from sliding
If your top mattress keeps sliding off, make sure the two are the same size and that there is enough grip between them. A correctly sized top mattress and a suitable non-slip underlay can help keep it in place. Worn or damaged materials may also contribute to the problem, so check the condition of both if the issue persists.
What causes a top mattress to slide?
A top mattress can slide for several reasons, from an incorrect fit to insufficient grip between the surfaces. Identifying the cause can help you choose the right solution.
- A mismatch in mattress and top mattress size: If your top mattress is smaller than your mattress, it may shift into the space around its edges. If it is too large, it may hang over the sides, making it more likely to move out of position.
- Worn mattress or top mattress materials: Over time, the fabric and filling of a mattress or top mattress can deteriorate. Changes to the surface may reduce the grip between the two, making it harder for the top mattress to stay in place.
- Insufficient grip between the surfaces: Some mattress and top mattress materials provide less friction than others. If there is not enough grip between the two surfaces, your top mattress may gradually slide out of position, particularly when you move during sleep.
- Frequent movement during sleep: If you tend to toss and turn, your movements may cause your top mattress to shift over time. This can be more noticeable when the top mattress does not fit properly, or the surfaces underneath provide insufficient grip.
Why should you avoid having your top mattress move around?
A sliding top mattress can create uneven support, gaps between sleeping surfaces, and reduced comfort during the night – all of which ultimately result in reduced sleep quality.
“A top mattress should help improve comfort, not disrupt it. Ensuring a proper fit and stable foundation can go a long way towards keeping your top mattress in place and supporting a more comfortable night's sleep.”

What can you do to keep your top mattress in place?
The best way to stop your top mattress from sliding depends on the cause. Start by checking its fit, improving grip between the surfaces, and assessing whether wear or damage is contributing to the problem. In some cases, a properly fitted sheet that securely covers both the mattress and top mattress may help reduce movement.
1. Make sure your mattress and top mattress are the same size
One of the simplest ways to stop your top mattress from sliding is to ensure that it matches the size of your mattress. A correctly sized top mattress should fit neatly across the mattress without leaving gaps at the edges or hanging over the sides.
If your current top mattress is too small or too large, consider replacing it with one that matches your mattress dimensions. It could also be the other way around; if your mattress is too small or too large, replacing it with one of a more suitable size could help improve stability.
2. Use a non-slip underlay to improve grip
If your top mattress fits correctly but still slides around, there may not be enough friction between the two surfaces. Placing a suitable non-slip underlay between your mattress and top mattress can help improve grip and keep the top mattress in place.
Choose an underlay designed for this purpose and make sure it is compatible with your mattress and top mattress. A suitable rug underlay may also be an option if its material and design are appropriate for use between mattresses.
3. Check whether your top mattress needs replacing
If your top mattress continues to slide despite fitting correctly and having adequate grip underneath, check its condition. Worn fabric, deteriorated filling, or other damage may contribute to the problem.
If your top mattress is worn out, replacing it may help it sit more securely on your mattress. Read our guide on when to replace your top mattress to help assess whether it is time for a replacement.
How to stop two top mattresses from sliding apart
If you use two top mattresses side by side, they may gradually move apart and leave a gap between them. First, make sure both top mattresses fit the bed correctly and that their edges meet neatly in the middle.
If they continue to separate, a suitable non-slip underlay beneath each top mattress may help reduce movement. You can also consider whether a single top mattress sized for the entire bed would be a more practical solution, provided it is compatible with your mattress setup.
