SilentnightSelf Heating Double Mattress Topper - Warm Cosy Mattress Pad Topper Featuring Heat Reflecting Foil and Thermal Lining to Retain Heat - Double

Nicely made, fits great is comfortable and does keep the bed warmer.

Now purchased two of these toppers, cant believe the difference it has made, already have a Winter tog quilt on the bed but couldnt get warm despite a heated wheatbag at my feet, had to throw a travel rug on top before I could get warm enough to sleep, this self heating topper arrived just in time to face the coldest night so far this winter, minus 4 degrees, the difference was noticed immediately, the topper somehow felt slightly firmer than the mattress without adding height, but very noticeable was the absence of cold from the mattress as you lay down, the heat was soon spreading into a cosy warm bed without the need for supplementing extra covers on the quilt , had to kick the wheatbag out as well, to be honest I wonder if I could revert to the Summer weight tog the bed was so warm

It works but don't expect miracles. The technology is simple enough, it stops heat from your own body escaping into the black hole of a cold mattres. Makes bed a bit cosier, but its not like electric blanket

Really well made, also like fact you can reuse the bag it's packaged in. All edges seamed well, good elastic straps to fit at each corner. Didn't take as long to get warm in bed, felt much more comfortable on bare feetand legs and retained heat throughout the night

Very warm and cozy. I like it.

Adds an extra layer of comfort to the mattress & retains body heat well

A great product that has helped keep me warm in bed without having to turn heating up. Within a minute or two of being in the bed you feel lovely and warm and wake up in the morning feeling warm still.

Keeps you warm but you do not overheat - brilliant.
