Q & As


Dreamland 6987 Sleepwell Mattress Cover, Kingsize 4.6 5 57 57
heated mattress cover I brought this for us as a surprise a month ago - and every night we use it we have happy faces! Just turn on the switch as you are preparing for bed and in five minutes you have a toasty warm bed to snuggle into. It is a bit expensive, but well worth it to see the smile on the face of your loved one - and I enjoy it too!! 15 April 2014
Socket is in the wrong place! The blanket does work well for heating control and is comfortable to have on all night on low settings. I have never understood though why the socket that the control cable attaches to has to be in the location it is?! It is right under your elbow / lower upper arm and is uncomfortable at times to sleep on if you happen to roll onto it - which is often. Why the designers of these blankets can't have a longer cable for the socket to be off the top of the bed or even put it right up in the top corner under your pillow is beyond me. My husband (who doesn't use his half as is always hot) is wanting to cut out his socket so he doesn't keep getting woken up when he rolls onto it!! 11 March 2014
Great product My wife and I are very pleased with this purchase. Having never used an electric blanket we have finally joined the ranks of the elderly in our late 50s and wonder why we didn't do so years ago. Getting into bed is so comfortable even on the coldest night. We barely notice the wires or the junction boxes near the bed edges and the digital controllers are superb - we usually use the 1 hour timers so it doesn't matter if we forget to switch off. 22 February 2014
Dreamland 6987 Sleepwell Mattress Cover King size Happier with this blanket although had similar product before. Replaced other one after 3 years because got new bed. Fits the Deep Mattress, and the controls are much better and do what we want. Comfortable to lie on too. 18 February 2014
Such a comfort! I am so thrilled with my Sleepwell mattress cover, I don't know why I didn't get one years ago. It is such a comfort on a cold night to get into a warm bed, it helps induce sleep. I suffer with aches and pains on waking in the morning, but if I pop it on for just an hour before getting out of bed it helps to ease the pain. Wonderful. 04 February 2014
Absolutely brilliant. How did I live without this. Lovely warm bed to get into at night. Having separate controls for each side of bed is perfect for me. Husband goes to bed much earlier than me but now we can both get into a warm bed 28 January 2014
Excellent product Had difficulty finding a cover that would fit our oversize mattress but this is perfect. It has a very stretchy fabric skirt that tucks under the mattress and the warming area is extensive. 16 January 2014
Unfortunate unreliability ruins a potentially excellent product I don't usually do reviews but I feel I should point out a particular issue with this product which has resulted in two failures and a final return for a refund. The first one worked well for a week and then my wife's side refused to switch on. Changing the fuse did nothing so John Lewis replaced it. The second one worked for about a month before developing the same fault. I think it is fair to give a product a second chance but not a third. Steer clear if you see any other similar reviews, otherwise it is an excellent product, amazingly quick to warm up - which was why we bought it. Our friends suggested it to us but they have since admitted they had to replace theirs out of warranty due to a fault. The blue light, as people say in other reviews, is far too bright. It really lights up the ceiling but a bit of electrical tape over the LED would stop that from being a problem. I didn't get around to trying it though! 14 January 2014
