Hey Kyle,
We are sorry that this topper sinks and is sliding down on the mattress.
While this topper is designed to sink less than the thicker profiles, it is still designed to provide a softer feel and will sink when weight is on it. Are you wanting a softer feeling bed or are you looking for something with more support?
If you are wanting a softer feeling bed still, then a topper made of a different material should be more comfortable for you. However, if you are wanting more support, then it may be time to invest in a new and firmer mattress instead.
Additionally, a fitted sheet should be enough to keep a topper in place. However, since it is still moving around, we would be glad to send a complimentary non-slip pad if you are interested.
Your satisfaction is important to us and we will work with you to find a solution. Please email us at: online@lucidmattress.com with more information so we can quickly assist you.
Thank you!
Lucid. Beds for the Whole Family.
