Under Bed — The under-mattress bed warmer: a warm, dry bed every night

Under Bed goes under the mattress and takes the chill off your bed before you get in. Its gentle, dry heat rises through the mattress, reduces moisture and leaves it fluffy and comfortable: you get into bed and it is already warm, with your usual winter duvet.

A 180 × 60 cm heating panel that warms the base of the bed. It works on slatted bed bases and on solid board bases, such as upholstered bases or storage beds. During the promotion, the panel comes inside a free fabric cover, while stocks last.

3-level power controller, automatic shut-off after 10 hours and a 45 °C safety thermostat. The first time, leave it on for more than 2 hours to dry out accumulated moisture; after that, simply switch it on 1 hour before going to bed. Within a few days of use, the mattress is in optimum condition.

Recycled cardboard and no paper

Our boxes are recycled cardboard, with no plastic coating and no glossy finish. New boxes are unprinted: printing a box uses ink, solvents and energy and makes the product dearer without giving you anything. For some models we are using up every last printed box we have in the warehouse before moving to unprinted recycled cardboard: throwing them away would be a waste.

And there is no paper inside. The instructions and the warranty are online, always at hand, and they never get lost. That saves paper and ink, and they are always up to date: if we improve something, we update them straight away.

Frequently asked questions

How is it installed?

It goes under the mattress, on the slatted bed base or on a solid board base (upholstered base or ottoman), and you plug it in. No tools are needed.

How long beforehand should I switch it on?

The first time, leave it on for more than 2 hours so it dries out the moisture the mattress has built up. After that, on a daily basis, simply switch it on 1 hour before going to bed. Within a few days of use, the mattress is in optimum condition.

Does it really remove moisture from the mattress?

Yes: its dry heat rises through the mattress and reduces moisture, which helps to prevent dust mites and unpleasant odours and leaves the mattress softer. As well as taking the chill off when you go to bed, it looks after your mattress.

Do I need to change my bedding?

No. Use it with your usual winter duvet or blankets: the warmer the bedding, the better the heat is retained.

How is it adjusted?

With its 3-level power controller: a high setting to warm the bed quickly and lower ones to keep it pleasant. It also has a 45 °C safety thermostat.

Does it switch itself off?

Yes: it switches itself off after 10 hours of continuous use, in case you forget to turn it off.

If the bed warmer switches off, how do I reset it?

It switches itself off after 10 hours, so you can sleep soundly even if you leave it on. For the next night, set the control to 0 for 5 seconds and choose the level again: ready to warm the bed an hour before you go to bed.

Does it come with a cover?

During the promotion, the panel comes inside a free fabric cover, while stocks last. It protects the panel during shipping and in everyday use, and can be cleaned with a damp cloth.

What warranty does it have?

It has a 5-year warranty, plus 90 days to return it if you are not happy.

What do I do with it when it stops working?

It is an electrical appliance, so it does not go in the bin. Take it to a recycling point, or hand it in at the shop when you buy an equivalent one, as the waste electrical and electronic equipment (WEEE) rules require.
