Carpet Underlay

Carpet underlay is the quietest upgrade you can make to a home. The right underlay makes your new carpet feel softer underfoot, sound quieter, stay warmer in winter and wear beautifully for years longer. It’s a small detail that changes everything about how a room feels.

Sotto’s carpet underlay collection is a considered edit of premium PU foam underlays from trusted names like Cloud 9, Tredaire and our own Sotto Bronze, Gold and Platinum ranges. Every underlay here has been chosen for the same reason: it makes a real, noticeable difference to the carpet on top of it.

How to choose the right carpet underlay

The thickness of your carpet underlay is the easiest place to start. Thinner 6mm to 8mm underlay suits hallways, stairs and rooms where door clearance is tight. A plush 10mm or 11mm carpet underlay is a beautiful choice for bedrooms and living rooms, where you want that deep, soft, bounce-back feel underfoot.

Tog rating tells you how much warmth your underlay will hold in. A higher tog means a cosier, more insulating floor, which is lovely in bedrooms and upstairs rooms. For underfloor heating, though, you want the opposite: a specialist underfloor heating underlay with a low tog rating, so the heat can travel up through the carpet and into the room rather than being trapped below.

Why quality carpet underlay is worth it

Good underlay genuinely extends the life of your carpet. It absorbs the everyday pressure of footsteps, stops the backing from wearing against the subfloor and keeps the pile looking fuller for longer. It also softens sound in the room, which is especially welcome in family homes, upstairs rooms and flats.

Every Sotto carpet underlay is manufactured in the UK to high standards, with a focus on comfort, durability and thermal performance. Whether you’re after a hard-wearing underlay for a busy hallway or the most luxurious 11mm underlay we sell for a quiet bedroom, you’ll find it here.
