If you mainly want warmth around your back or lower back, shape matters. A longer 50x30cm cushion fits easily behind the lower back or neck, while 45x45cm gives broader coverage.

Returns and warrantyTargeted back warmth
Long heated cushions for back and neck
50x30cm models are useful when you want to place warmth more precisely around lower back, neck, belly or lap.
Lower back
For lower back warmth, a longer cushion is often useful because it fits well between back and chair without taking too much space.
Neck and shoulders
A narrower format is easier to place around neck or shoulders. Always use the product comfortably without folding or squeezing it.
Sofa or office chair
Use Warmpi where you sit for longer: sofa, armchair or desk. Direct contact feels best.
When to choose 45x45cm
Choose 45x45cm if you also want a normal-looking cushion that can stay on the sofa.
