Q & As

Rated 4.7 out of 5 by 89 reviewers.
Rated 5 out of 5 by Sleep well with Sleepwell Electric Blanket Bought because my old one stopped working. I did not want a fleece mattress cover but a cotton cover and this was ideal. Would recommend this product 06 April 2016
Rated 5 out of 5 by Brilliant fit and functionality! Heats up quickly and feels very comfortable to sleep on. Dual controls are very useful as my husbands preferences are different to mine. An excellent buy, especially with John Lewis's 3 year warranty. 09 February 2016
Rated 5 out of 5 by LOVE this blanket By far the best electric blanket I have ever owned. Heats up very quickly, my husband loves that he can put it on the timer, especially when I am away! The fitted sheet style is great, as it makes it VERY easy to fit to the bed. The controls position is good, easy to access and does not dig in when you are sleeping!! Some have said that the heat does not come up the bed far enough, but I haven't found that to be the case. Definitely worth the money and with the JL 3 year warranty, much better than buying from other retailers! 08 February 2016
Rated 4 out of 5 by Good quality but... This is an excellent electric blanket. It heats quickly and does not reflect heat like some fleece blankets. The controls allow one or nine hours of use and there are six heat settings. That said, I have mine on a timer* and sometimes the heat setting changes from 6 (hot) down to 4 (warm). * Actually it's on my home automation system and I turn it on just before I go to bed. 26 January 2016
Rated 5 out of 5 by Excellent quality product Does exactly what it says on the tin. Put on for 5-10 minutes before bed and the bed is really cosy. Useful features. So glad I bought one. 26 January 2016
Rated 5 out of 5 by Dreamland 6897 Fab product, dual controls for split side temp control for personal preference, a quality product from a name that you can trust for safety standards & fit. I Can highly recommend to all, 12 January 2016
Rated 5 out of 5 by Do not miss out on this product We have been promising ourselves a new blanket for years but were afraid that the new ones were inferior to the ones with bendy wires.However this is a must for the oldie,who forgets to put the blanket on and get a row from the significant other.It really does heat up in 6 minutes and is a very comfortable extra layer on the bed.Worth every penny. 12 January 2016
Rated 5 out of 5 by Electric blanket I bought this electric blanket following good advice received from the sales assistant. It fits the bed well and heats up very much more quickly than any blanket I had previously owned. It warms the bed almost instantly, thus being very energy-efficient. 07 January 2016
