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

For rugs placed on wood, laminate, vinyl, stone, tiles or other smooth flooring, our Supergrip Anti-Slip Underlay is the recommended choice.

At first glance, Supergrip may look similar to many lower-cost underlays available elsewhere. The difference is in the performance.

Our Supergrip is a higher-quality, more durable product designed to grip effectively and continue working over time. Cheaper alternatives may look much the same, but can quickly lose their effectiveness and need replacing. Supergrip costs a little more because it is made to work properly and last.

With a thickness of approximately 3mm, it provides excellent grip without adding unnecessary bulk beneath your rug.

Choosing the right underlay is simple:

  • Rug on fitted carpet: choose Foxi Anti-Creep Underlay
  • Rug on hard or smooth flooring: choose Supergrip Anti-Slip Underlay

Why Choose Frith Rugs Supergrip?

Not all rug underlays perform in the same way. While many products may appear almost identical, the quality of the materials and construction makes a significant difference.

Our Supergrip has been selected because it offers:

  • Strong, dependable grip
  • Long-lasting performance
  • Excellent stability on smooth floors
  • A discreet, low-profile 3mm thickness
  • Better durability than many inexpensive alternatives

If you want an underlay that does the job properly and continues to perform, Supergrip is worth the difference.

How to fitFoxi underlay

How to Fit Foxi Anti-Creep Underlay

Foxi is quick and straightforward to install:

  1. Make sure the carpet and the back of the rug are clean and dry.
  2. Lay the underlay with the white side facing the fitted carpet.
  3. Position the printed side against the back of the rug.
  4. Centre the underlay so it supports as much of the rug as possible.
  5. Trim it so that it sits just inside the edges of the rug and remains hidden.
  6. Carefully lower the rug into place and smooth it flat.

The underlay may be supplied slightly smaller than the rug so that it remains concealed. Larger sizes may also be supplied in more than one piece; this does not affect its performance.
