Q & As

Rated 4.6 out of 5 by 32 reviewers.
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
Rated 5 out of 5 by Super bedtime Bought this Electric Mattress Cover to replace broken one. Fits great on deep mattress and with individual controls for either side it is better as I dont like my side too hot, but my other half likes his side toasty, so everyone is happy. Bring on the cold weather. 03 November 2015
Rated 5 out of 5 by Does what it claims Have had this type of electric mattress cover previously and always been pleased. This one bought to replace previous one and the newer model has much better and easier controls. Have washed previous ones and they do wash well. 03 November 2015
Rated 5 out of 5 by Relaxing! I like the idea that the mattress cover can be machine washed. 12 May 2015
Rated 5 out of 5 by Wonderful - wish I'd bought it sooner! We've found this to be brilliant; really comfortable, separate controls, fast warm up, able to leave it on all night if desired. Couldn't be better. 31 March 2015
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
