Alvar™ Seat Cushion

The Alvar™ Seat Cushion is an ergonomic seat cushion built on a Hypercell cell structure with Hyper Foam. The construction spreads body weight across a wider area while keeping the pelvis stable. A non-slip underside holds it in place on car seats, office chairs, kitchen chairs, and wheelchairs.

Cell Structure Instead of Ordinary Foam

Standard foam cushions compress permanently and trap heat. The Hypercell construction with Hyper Foam is built to hold its shape rather than flatten, and it stays cool in use. The cell structure moulds to your body without losing its form, distributing load evenly across the seat.

How to Use the Cushion

Place the cushion on the seat with the non-slip underside facing down — the base keeps it in position without straps or fixings. It is designed to be used without a cover, so the cell structure can move freely. If you want extra protection, a very thin, stretchy cover that follows the cushion’s shape is the recommended option.

Where It Works

Alvar™ adapts to whatever chair you’re on. It suits car seats on long drives, office chairs through a working day, kitchen and dining chairs, and wheelchairs for extended seated use.

Put an Alvar™ Seat Cushion on the chair you sit in most and take the pressure off.

Frequently Asked Questions

Does it hold its shape or sink over time?
The Hypercell construction with Hyper Foam is built to spread load without quickly going flat, so support stays even month after month.

How is it different from a cheap foam cushion?
Ordinary foam flattens within weeks and traps heat. Alvar™ uses foam technology built to last for years and stay cool.

Does it come with a cover?
No. It’s designed to be used uncovered so it keeps its pressure-spreading properties. A very thin, stretchy cover is the only recommended addition.

Will it slide around on my chair?
No. The stable base and non-slip underside keep it in place.

Which chairs can it be used on?
Car seats, office chairs, kitchen chairs, and wheelchairs.
