Q & As

Rated 4.6 out of 5 by 38 reviewers.
Rated 5 out of 5 by Excellent product Extremely happy with this electric blanket. Duel sided controls are great especially when my other half is cold and I am too hot. Very easy to operate and very easy to change settings. My husband has bad eyesight and he finds the controls very easy to use and the blanket heats up to max. very quickly if required. Recommend this product. 13 February 2016
Rated 5 out of 5 by great product was a gift and and was very much appreciated, apparently really does the trick! 26 January 2016
Rated 5 out of 5 by Brilliant. I am getting a much better night's sleep now. The twin controls suits us really well because we like different temperatures to ensure we do not wake up cold and end up pinching more than our fair share of quilt! 19 January 2016
Rated 4 out of 5 by Perfect for all night warmth Streets ahead of other electric blankets when it comes to all night heat - you never get over powered by the heat because it adjusts to your body temperature. The only downside is the preheat is not as warm as I have experienced with other blankets. The other minor annoyance is the timer sets for 9 or one hours and nothing in between which would be useful. We brought the first blanket for use in our caravan and I was so impressed I had to have one for the home. 07 January 2016
Rated 4 out of 5 by Good product but annoying light. The blanket is really warm and has many temperatures to choose from. I love that it is dual control. My previous dreamland blanket was better in the sense that it heated up faster and you could choose more time settings. This only gives two options. My main gripe with the blanket is the light on the controls is so bright it lights the whole room up! Turned it upside down in the end so I could get some sleep! 29 December 2015
Rated 5 out of 5 by O M G it's fantastic Bought one of these as a present 1 year ago and the recipient was delighted we have since purchased three more including one for ourselves after resisting many years. The dual control is a superb idea. Body temperatures differ so with this you can set each side to suit your individual need. It has 1 to 6 heat setting. On no.6 it warms up in around 5 minutes so you can turn it on and it will be warm by the time you get in. It has function to allow you to set it to go off automatically after 1 hour or 9 hours so you can put it down to number 1 and go to sleep save in the knowledge it will turn off. Cant recommend this item highly enough. Go to bed with a satisfying grin on your face! 29 December 2015
Rated 5 out of 5 by Nice and toasty on cold nights I just love this electric blanket. It fits by an elastic edged trim which secures below the mattress. It has more or less stayed in place too. My previous blanket was the tie type and that was forever slipping around the bed and I quite often ended up with the controls stuck in my back. I was tempted to order an oversize blanket to avoid this happening, but decided to go with the actual size of my mattress. Perfect fit. It heats up immediately and on the highest level I would really struggle to keep it on for more than 10/15 minutes when I'm in the bed as it is red hot! Exactly what I needed. The dual control is great too. My husband is much warmer blooded than me. I would definitely recommend this blanket 24 November 2015
Rated 4 out of 5 by Dreamland mattress cover This is an excellent product and fits snugly over the mattress eliminating wrinkles. The timer is a bonus and the mattress cover heats up quickly, which is great on cold evenings. 24 November 2015
