Your cushion. Added warmth.
Keep the cushion cover you love and add warmth underneath. The Warmpi heated inner cover fits between your own filling and decorative cover. You use a ready-made heating system, with no sewing of heating elements or electrical wiring to assemble.
incl. VAT · supply your own filling and decorative cover
A 45×45 cm heated inner cover, your own suitable cushion insert or loose cushion filling, a decorative cover and a suitable 5V/2A power bank. The inner cover has a zip, a short USB-A cable and a rear power bank pocket. A cushion insert, filling and decorative cover are not included.
Check both your filling and outer cover. There must be room for the 45×45 cm inner cover, the zip must close normally and the control must remain accessible. A very thick insert or tight cover will not automatically fit. Ask for advice first for 50×30 cm cushions or other shapes.
Open the zip and place your cushion insert or suitable loose cushion filling inside the heated inner cover. Distribute the filling and keep the cable and connector clear. The panel is at the front: the heated area is 30×30 cm, not the entire 45×45 cm cushion.
Connect the USB-A cable to a suitable power bank and place it in the rear pocket. Pull your decorative cover over the assembled cushion. Keep the control accessible beside the zip and avoid trapping the cable or plug. Follow the product instructions to switch on and select one of the three heat settings.
If you already have a suitable power bank with a 5V/2A output, choose the inner cover without a power bank. Check that your battery fits the 20×12.5 cm pocket; the integrated USB-A cable is 15 cm long. You can also choose a Warmpi 10,000 or 20,000 mAh power bank. Your selection on the product page determines the price and what is included.
A grain-filled or rice-filled heating pad is a different product with a different heating method. This guide uses a complete electric inner cover inside your cushion. Never put the electric inner cover in a microwave or modify its panel or wiring. Watch the product instruction video before first use.

It is designed for suitable 45×45 cm cushions. Size, filling thickness, zip and access to the control all matter. Warmpi can assess other sizes or constructions separately.
No. It sits around your filling and underneath your decorative cover, so your own colour and fabric stay visible.
Not with a suitable cover and filling. You use the zip and existing connectors rather than building an electrical heating element.
Remove it from the electric inner cover and follow its own care label. Do not assume that those washing instructions also apply to the heated inner cover; use the product-specific instructions for that. Never wash the power bank.
