Hello there,
The supplier has advised the following for the Slumberdown Cotton Comfort Mattress Protector - Single:
"Yes, there is no reason why you couldn’t use the product over the top of an electric blanket. We usually say, a protector should go on first as this is designed to protector you mattress giving it a longer life. Then your electric blanket goes on top, finally your fitted bed sheet."
(We'd also advise that you check the electric blanket’s specs too so as to be sure that it’s safe to use with a blanket of this type before considering its use).
Thank you for using Q&A.
The answer is incorrect as at 8 July 2025.
Having bought it today it is the cheap stuff you described.

Hello.
