Which Side of the Bed is the Controller Switch

OK I am a bit thick. I am simply told the Controller is on the Left hand side. But is that on the Left when you are laying on the bed or on the Left when you are looking at it fitted on the bed. In that case the Controller is on the Right hand side when you are laying down. Asking this question because I would obvoiusly like to operate the Controller when I am laid down.

1 Answer

Hi Billh,

I have looked into this for you and can confirm that when lying down and using this product the controller will be on your right.
When looking straight on at the product from the foot of the bed the controller will be on the left.

I hope this helps,
Thank you for using Argos Q&A


Does it HAVE to be kept on all night

1 Answer

Hi, thank you for your question.

Having looked into your query, I can advise that the Silentnight Essentials Heated Underblanket - Double does not have to be kept on all night. It is at your own discretion which setting you decide to use. This item has 3 heat settings that are suitable for all night use.
However, if you chose to turn it off then you may do so when you require, suited to your body temperature.

Thank you for using Q & A.


can I use this with a memory foam mattress?

2 Answers

I've looked into this too as we all have memory foam toppers on our beds in my house and have found that makers of Memory Foam products advise that as memory foam is temperature sensitive and softens from your body’s temperature then the heat from an electric blanket will soften it further. As a result you may find that too much excess heat will not allow your mattress or topper to support you correctly.

They advise to use electric blankets with memory foam products only for short periods of time prior to bedtime to warm it up and never to keep it switched on whilst in bed, which isn't something I'd personally do anyway.


Thank you for your question.

I have looked into this and I can confirm that the Silentnight Essentials Heated Underblanket cannot be used with memory phone products.
