Q & As

Dreamland 6988 Sleepwell Mattress Cover, Super Kingsize 4.8 5 43 43
Great product Heats up quickly, very helpful that there are 2 controls one for each side of the bed. 17 December 2014
Bliss! This seemed like an extravagant purchase but it is wonderful - worth every penny. The superkingsize fits easily over a very large/deep mattress. The fast warm-up means no waiting around if you come home late. The night sensor which (noiselessly) adjusts the temperature to suit you as the night progresses is a marvel, though even the bottom setting is warm. All in all, this is making winter bearable! 16 December 2014
Can't Live Without It Heaven - an excellent electric blanket and even better because it is a mattress protector. You won't find a better one. 09 December 2014
Comfortable and dreamy We have a very deep Visprung mattress and this fitted perfectly, it add a nice comfort layer and warms the bed perfectly with easy to use dual controls. I have had it set on number 5 and it does not get very hot, just warm therefore if you are looking for a heated blanket which gets very warm I'm not sure this is for you. 09 December 2014
Brilliant - best purchase of the year I had been thinking about getting an electric blanket for years and finally got around to it this year. Now that I have my only regret is that I didn't but it years ago. No more cold feet and the warmth is comforting without making you too hot. I thought the dual control would be essential as my husband wasn't as keen on the idea but now he is as big a convert as I am! 18 November 2014
Super Efficient ! We were directed straight to the right spot. Described what we needed to a very courteous assistant, who immediately produced the exact article to fulfill our requirements. And it is excellent. All done In the twinkling of an eye! That would be hard to beat anywhere. 20 April 2014
Excellent buy, although expensive. Easy to use. Heats up quickly. Look forward to going to bed. 15 April 2014
Heaven on Earth This is one of the best products I have ever purchased. I look forward to going to bed every night. It is sheer heaven. 18 February 2014
