How can a mattress be kept from slipping on a sofa without causing damage?

Non-slip mats or rubber rug grippers create friction between the mattress and sofa, preventing unwanted movement while protecting both surfaces from damage.

For instance, contemporary Australian furniture brands like Koala, Fantastic Furniture and Eva often design products with non-slip features or recommend similar accessories to enhance stability.

Using these mats or grippers is a simple and cost-effective way to keep a mattress securely in place on a sofa, without relying on adhesives or hardware that could harm the upholstery.
