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.

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.

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.

Heats quickly and evenly
Heats up quickly. Have not noticed any cold or hot areas. Heating element wires are unintrusive, they are not noticeable when lying in bed. Much better than a heated blanket. Does not get folded over to create a hot spot like a blanket.

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.

DO NOT BUY!!!
I spent a lot of time reading reviews and comparing before I bought this. Hopefully I can help you not make the mistake I made. There are so many bad things about this mattress warmer I hope I can list them all. 1 price; It is really expensive for the poor quality. I admit I did think it would be better because of the price point (over$80 for twinxl). 2 Thickness/ padding; there isn't any buffer. It feels and sounds plasticky because of the waterproofing, you can feel every wire. 3 Heating. the heating is terrible. there are no wires at all down where your feet go so the bed does get warm but the only way to keep your feet from freezing is to sleep in a fetal position. My feet are my biggest concern. I bought this so I didn't have to try to sleep with socks on in the winter, I hate that. Another thing with the feet is there's a huge honking plug there. You have to sleep crooked to keep from hitting the big hard plastic bump on the left and on the right is a huge sewn on directions and warning label which is even more plasticky than the pad itself (and therefore even colder). 4 Plug; Due to the plug being at the bottom the cord then runs all the way back to the hear of the bed to plug in which we had to run under the mattress on top of the box spring to not interfere with under bed storage. 5 The remote; The remote is HUGE its like double the size of a computer mouse and takes up a ton of room. It also does not have a memory so I would choose heat level 3 and 3 hours and every night I had to plus sign up to 3 from 1 and minus sign down to 3 from 8. For over $80 it should remember the setting and I should only need to change it if I change my mind, annoying. I ended up returning this Serta and purchasing the Bwarm mattress pad and it solved every problem. It is not waterproof so I just put my mattress protector over it. It has a thick quilted removable topper over the wires so you can't feel them. it has 2 zones feet and body that can be set separately and it remembers the settings on it's much more appropriately sized remote. The plug is at the head of the bed and on the vertical side where you can't feel it making for far less cord to mess with. I am much happier with the Bwarm all around.

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.
