Cozy warmth on cold nights
This heated mattress pad has been wonderful for cold nights. It warms up quickly and evenly, the controls are easy to use with multiple heat settings, and the auto shut-off gives peace of mind. Preheating the bed before I climb in is a game-changer in winter. It's soft, fits my mattress snugly, and washes well. A cozy upgrade I wouldn't want to go without.

Heated mattress pad
Nice heating pad for chilly nights saves on turning heat up to sleep and warms the bed instead of having a heated blanket over top of you. Plus the multiple heat setting and timer function makes it really nice adjust timer for how long you think you might sleep and to comfy temp and it saves it so each time you turn it on it returns to that setting even after a power outage.

Oh, WOW!
My bedroom is upstairs and I leave the baseboard heat in there off most of the time. There is a pellet stove there and, when it gets really cold outside, it is on. Like today, for example! So: it is cool in the bedroom. I have an electric blanket that I've used for years to 'preheat' my bed before jumping in. But I felt it wasn't quite doing the job. Looking for a mattress pad heater, after 'looking' at others, I landed on this one. When I go in to do my evening ablutions, I turn on both the blanket (it has a 'preheat' setting) and the mattress pad, usually to 6 or 7. By the time I am ready to jump in bed, it is TOASTY in there! The title of this review comes from what I said the first time I crawled in! Oh WOW! OMG would be fitting as well! I have never left it on all night: I preheat the bed, then turn it off, and leaving the blanket on the lowest setting or, depending on the room temperature, turn it off as well. Controls are easy to figure out. Seems to be a well-built unit. Lying on it adds another layer to my padded mattress which also has a mattress pad on it! Double comfort! I am pretty sensitive and, opposed to other post on this, I do NOT feel the heating coils. It might be because I use thick flannel sheets, but I don't think I would feel them even with regular sheets. This pad is doing exactly what I bought it for!

Yes it was hot, hot, hot!
We replaced a unit that we have had on our air adjustable air mattress for years. Our old one was a very simple unit with a heat setting that would stay on until you shut it off. This unit took a bit to get used to with adjustable heat settings and auto shut off that is selectable. It took a bit to get used to it as somehow it stayed on all night and even at the lowest setting, it is extremely warm. If you are cold blooded, this is the unit for you. If you want the bed to warm up quickly, I would turn it on for 10 to 15 minutes and then turn it off. I saved quite a bit over what Kohls was asking for the same identical unit.

it’s got a timer, and each side of the bed it’s own temperature gauge.
Heaven! What a wonderful way to stay warm and cozy even at -18! Never used our room heater. Couldn’t wait to get into bed!!!!!!!

It’s a Heated Sheets
Bought this for my parents, and they love it. Easy to install, weight and durability are good, heats up well and helps them with their backs and muscle recovery.

Roasty Toasty - I'll never be cold again
This thing is amazeballs. It works too well- this is day 2 of having it on my bed and my husband and I both feel like rotisserie chickens after having it on for a few mins. We haven't found the sweet spot yet for what level to put it on. We've went hard and started at level 10... We are in fact not in need of heat that intense. We live in North Carolina. 😂 I am not disappointed with it working too well, I hate being cold and I bought this because I've been huddled under a heated throw blanket since this particularly harsh winter started. Husband didn't want to like it but he loved it immediately. I can crank my side up to hellfire hit and his side stays at whatever temp he wants. Annnnd since it helps ease his diagnosed back issues, I can get my FSA to reimburse me. Huge win. 10/10 would buy again.

Too hot, and you can feel the wires
This mattress heater is decent, but it's a significant downfall to have just 5 heat settings, especially when the lowest setting is too hot. My previous one from another company (Electrowarmth) had an analog control dial, so you could find tune it to your heart's content. It was designed for 12v use, so basically for truckers and RV'ers like me. But it's super easy to connect it to a 110v if I want, by sniping the tip off an old laptop power adapter; doing the same to the 12v plug; and twisting the wires together. Boom, 12v-to-110v. Another smaller issue with this one is that I can feel the heating wires in my back. They're not poking out or anything of course, but just very close to the sleeping surface, which wasn't the case with my old one. In fact, the only reason why I decided to try this one instead of just ordering another one of the same kind that I already had was that this one arrived in a couple days, and the other one wouldn't arrive for a couple weeks, which was well after I actually needed it. Oh yeah, another minute issue is that they tell you not to safety-pin it to your mattress (because they are afraid you'll poke one of the wires and damage it), but it is rather loose in the middle, since that's where one gets in and out of bed. Whereas my old one simply sewed in tabs among the edges specifically for pinning, so it sat tightly/nearly underneath the sheets. Anyway, if you're fine with the points above, it's not a bad option, and I like the idea of having a built-in timer. But at least for me, the deal breaker is the lowest setting being too hot for my liking. Hope this helps!

Love it
I was searching for a high end matress protector (protect from liquids, etc) but also wanted a full bed heating pad. After reading about how some matress protectors conflict with full bed heating pads I thought this would be perfect. And it is. Top quality matress protector with a full bed heating pad built in. Easy to use controller with long cords (to the outlet and the wired controller to the matress protector). Couldn't be better. When I ordered I noticed a few reviews that had issues with warranty but based on my experience so far as long as you take care of it and follow the washing instructions etc I don't forsee any issues. And yes, it's even machine washable. Not the cheapest product on the market but honestly it's the best and worth spending the $$$ for a more comfortable sleep.
