Q & As

Rated 4.6 out of 5 by 78 reviewers.
Rated 5 out of 5 by Is the connector really a problem? When I set out to buy this product I was somewhat concerned about a number of customer reviews on the JL web site. A number of reviews had made some critical observations regarding the connector located on the blanket being obtrusive. Since this appeared in several reviews I decided to contact the manufacturers to see if this problem had been reported to them. There customer services advisors contacted me and said that in there view this was not a problem. They pointed out that some individuals who lie right on the very edge of the blanket might experience a "lump" which they find uncomfortable. However for most people who sleep away from the edge will not come across this phenomenon. I decided to take the plunge and buy the blanket which I must say is first class. The connector position is not intrusive to us and we hardly notice it is there! I have no hesitation in recommending this product. 10 December 2015
Rated 5 out of 5 by Works well Works well. One poster said the cables are placed uncomfortably, near pillows etc. I haven't had a problem with this. 09 December 2015

Rated 5 out of 5 by Super Blanket My Husband and I love this blanket it is so cosy and gives you the warmth exactly where you need it. The dual control is great as it gives us both our own individual settings. I have already recommended this blanket to all my friends. 02 December 2015
Rated 5 out of 5 by Have a a number of Dreamland excellent mattress covers Always a first class product with warranty and I continue to purchase as I so enjoy the controlled timer#warmth 01 December 2015
Rated 5 out of 5 by Really pleased with this product We've only had this product for a couple of months but so far so good. Main concern was the connector for the power-supply and how close that would be when you're sleeping but we haven't found this a problem at all. It sits a couple of inches in from where you lay but it's not right by the head so we really haven't noticed it at all. Blanket really comfortable - the independent sides work well especially if one of you likes a higher temperature. It heats up really fast- so far so good. 01 December 2015
Rated 5 out of 5 by Dreamland 6987 Sleepwell Mattress Cover, Kingsize Excellent product, gets very hot very quickly. Good quality, easy to use and fit to the mattress 01 December 2015
Rated 5 out of 5 by Dreamland 6987 Sleepwell Mattress Cover We bought this electric blanket to replace a fleece electric blanket we'd purchased some time ago from John Lewis. We are delighted with the padded cover, it fits our king size mattress perfectly. It has dual control so our independent heating needs at night are easily catered for. All in all a good purchase. 24 November 2015
