Q & As

Rated 4.8 out of 5 by 67 reviewers.
Rated 5 out of 5 by Wonderful The mattress cover is really easy to fit and set up, if fits just like a fitted sheet to keep it in place. We set the heat at level 6 (fast heat up) before brushing teeth etc and then reduce it to 2 or 3 before getting into bed. Why haven't we invested in one of these before? is a common comment. The bed is toasty warm and no longer do we have that 30 seconds of catching our breath with the coldness of the sheets. I thoroughly recommend this to anyone who hates trying to get warm enough to get off to sleep, no more bed socks required here. 08 January 2016

Rated 5 out of 5 by Dreamland 6988 Sleepwell Matteress Cover, Super Kingsize Brilliant item The best heated blanket we have ever come across. It's made a wonderful difference to our bed. The fitted blanket warms the whole of bed Padded quilt effect enhances bed too! Highly recommended 07 January 2016
Rated 5 out of 5 by Excellent product Love this blanket, heats up in five minutes, then can be set low to stay on during the night on a timer. Blue light useful if you need to go to the bathroom in the night. 07 January 2016
Rated 5 out of 5 by cozy underblanket Replaced our old one for the same again as it is such a good blanket. Nice to have dual controls and fitted corners. 07 January 2016
Rated 5 out of 5 by Wonderful! This was recommended to me by a friend - they raved about it! - and so we decided to buy one. We were not disappointed and we now know WHY they raved about it so much. The blanket heats up within a couple of minutes - you don't really need it on any longer than that - and the bed seems to retain the heat throughout the night. Such a great buy and would highly recommend to anyone thinking of buying one 07 January 2016
Rated 5 out of 5 by Makes such a difference Number 4 setting for 1 hour is perfect and it heats up so quickly. 07 January 2016
Rated 5 out of 5 by Fantastic heat This blanket is brilliant. We ve had electric blankets for years, but then bought a bigger bed. This blanket heats up quickly and stays on for 9 hours if you like. Controls are so simple and its very comfortable. great for just taking the chill off the bed. 22 December 2015
