Keep Your Rug Securely in Place with Premium Rug Underlay
Our underlay is designed specifically for rugs!
A beautiful rug should stay exactly where you place it. The right rug underlay helps prevent unwanted movement, keeps your rug looking neater and protects both the rug and the floor beneath it.
At Frith Rugs, we offer specialist underlay for rugs placed on fitted carpet and hard flooring. For rugs on carpet, choose our trusted Foxi Anti-Creep Underlay. For wood, laminate, vinyl, tiles and other smooth floors, choose our Supergrip Anti-Slip Underlay.
Stop Rugs Moving, Slipping and Creeping
Even a heavy rug can gradually move out of position. On smooth flooring, rugs may slide underfoot, while rugs laid over fitted carpet can slowly creep, ripple or bunch up with everyday use.
A good-quality underlay creates a more secure layer between the rug and the floor, helping it stay flatter and more stable. This means less time adjusting your rug and more time enjoying it.
Foxi Anti-Creep Underlay forRugs on Carpet
Rugs placed over fitted carpet can be particularly difficult to keep in position. The direction of the carpet pile, combined with regular foot traffic, can cause the rug to gradually move across the room.
Foxi Anti-Creep Underlay is our recommended solution for rugs laid over fitted carpet. It grips between the carpet and rug, helping reduce creeping, rippling and movement.
It is ideal for:
- Living room rugs
- Bedroom rugs
- Hallway runners
- Rugs beneath coffee tables and furniture
- Busy family spaces
- Areas with frequent foot traffic
Foxi is made from synthetic material and does not require permanent fixing or adhesives. Its approximately 4mm thickness also adds a subtle layer of cushioning beneath the rug.
With more than 30 years of proven use, Foxi is designed to provide dependable grip and long-lasting performance.
Made from synthetic material, Foxi leaves no sticky residue and does not need to be permanently fixed to the floor. Its approximately 4mm thickness also adds a subtle layer of cushioning beneath the rug.
Foxi has been a trusted name in rug underlay for more than 30 years. Unlike thin, low-cost alternatives that may quickly lose their effectiveness, it is designed to provide reliable grip, comfort and durability.

Supergrip Anti-Slip underlay forRugs on Hard Floors

Choosing the right underlay is simple:
