Q & As

Rated 4.5 out of 5 by 26 reviewers.
Rated 5 out of 5 by The Best This is the best electric blanket I have ever bought. Heats up within 5 minutes. Wouldn't hesitate to recommend. 09 December 2014
Rated 5 out of 5 by Super heated mattress cover We found this to be an excellent product with superfast heating for a quick bedtime warm up. It provides a very comfortable quilted mattress cover with dual controls and 6 heat settings (no.6 being the fast warm up before bed - it takes only five minutes or so to provide a really comfortable temperature. There is a control to set the heating to be on for 1 hour or 9 hours and then it switches off automatically. Very easy to use the only thing which would be an improvement is the length of the cable from the blanket to the control which could be a little longer as it tends to fall off the bedside table rather easily at times. All in all we highly recommend it and consider it to be excellent value for money. 18 March 2014
Rated 1 out of 5 by Disappointed This is my 3rd blanked in 25 years and it's very disappointing that the irritating features from the last dreamland fleecy blanket that I bought about 8 years ago are still present in this one plus they've added a few more to really bring out my Victor Meldrew tendencies. - The wires are no thinner than the one I bought 8 years ago and I can still feel them! - The socket bit where the controller joins the blanket is still at the side of the bed just below the pillow so I catch my arm on it all the time, and of course there's no way to check where this is before you buy the product and once opened you can't return it! The one part way down the bed is smaller thank goodness. - The controller is still upside down as I and I expect most people use it. - Now the press button temperature control only goes up so you have to cycle through all the settings if you want to change the temperature down a bit, which is tricky to do upside down. - Now the neon blue glow of the controllers when they turn themselves off is awe inspiringly bright. You truly will not believe how bright a pair of them is! It does warm the bed nicely, but so have all the blankets I've had over the years. Why have none of the issues with the last version of their top of the range blanket been fixed in all these years? Very disappointed! 30 January 2014
Rated 5 out of 5 by A must for cold weather... I bought this mainly for my partner who feels the cold (a common femal trait!?), she absolutely loves it - and so do I!! Dual controls are perfect, you can control the temperature of the own side of your bed. Machine washable and adds extra comfort as its basically a mattress protector. You cannot feel and heating elements and there are no cold spots!! Great product. 30 January 2014
Rated 5 out of 5 by Warm Bed Dual controls work fine and remembers your most recent setting. Warms bed rapidly. Easy to fit. 12 November 2013
Rated 5 out of 5 by So Easy and Convenient to use Fits my double mattress really well and is so comfortable. Cannot feel any wires or ruching of material to cause discomfort when laid on. 16 October 2013
Rated 5 out of 5 by Really useful product The nattress cover is very good quality, excellent fitting that provides the smoothness to the entire bed. Very good and safe power control pads with safe and natural heating down time as a result, it provides real joy and comfort in sleeping well. It has been a real joy and feeling safe in exiting the use of Hot Water Bottle. I would recommend its use especially to the elders, because its safe. 14 January 2013
Rated 5 out of 5 by Simply wonderful ! Couldn't believe how quickly this heated the bed. Great that it had "dual controls" for each side of the bed. I really don't know how we've gone so long before getting an electic blanket, but I wouldn't be without it now. Blissful!! 13 January 2013
