Q & As

Rated 4.4 out of 5 by 5 reviewers.
Rated 5 out of 5 by lovely warm bed excellent really fast heat up and no cold spots as it covers the mattress completely lovely 04 February 2015
Rated 3 out of 5 by Connectability This electric under blanket has connection on the right hand side only. No consideration is given to if RH side connection is not possible. I sent an e mail to Dreamland to ask them if anything could be done to have connection on LH side or longer cable to connect the cable to power socket on the LH side of the bed. I was told that it is not possible and if required I should reverse the blanket. It was a layman's solution to the problem as underside of the blanket is only covered with thin cotton sheet whereas the top is quilted . If the blanket is made reversable with quilted cover on both top and bottom then it could be called reversable to suit connection on any side of the bed. I am not happy the way it is now connected as the controller is lying on the bed itself on the LH side. 10 November 2012
Rated 5 out of 5 by So good I bought another one - see my top tip This mattress cover more than exceeded expectations. It's excellent quality, fits really well and performs brilliantly. It does what it says on the tin - the bed really does warm up in just five minutes. I thought my induction hob heated up quickly; I never thought I'd find a product that did the same on a bed. I'm now ordering another one, this time a double. Although these products are a little more expensive, they really are worth every penny. Well done John Lewis for stocking such brilliant products! TOP TIP: Measure your mattress size carefully before buying. There's a hygiene seal on the packaging which once undone, means you can't return the product unless it's faulty. 08 November 2012
Rated 5 out of 5 by Brilliant Blanket This is the best electric blanket I have ever owned. It is supremely comfortable, it heats up in 5 minutes if necessary, it is washable, and it has an amazing control. But best of all the skirt is deep enough for my mattress, (in contrast to the previous model), and this ensures a great fit. 16 March 2012
Rated 4 out of 5 by useful Fits better than any other electric blanket we have ever had 08 February 2012
