Exceeds expectations; defines next-gen bed heating. Superior app.
I’ve used heated mattress pads for decades because they’re super-effective, highly efficient, & convenient. They’ve looked like crap til now, & have all been at least 50% ungainly wiring harnesses & controls by weight. Awkward & dumb. Sunbeam set a new standard here, with a single, compact, extremely well-designed controller. It has 1 wall plug, & 1 cable which plugs into the bottom of the mattress pad. That’s for a queen or king, with split zones. You & your partner each want to control your respective side? Download the surprisingly well-designed & well-executed app & use your phone. Setup is easy, control is simple (even scheduling regular run-times), & it hasn’t crashed or lost its Bluetooth connection since I installed a month ago. In fact, 2 weeks in I bought a 2nd Sunbeam & scrapped an inferior product purchased earlier this year. I was amazed at how easy it was to add to the app as a new device, renaming both so we’d know which bedroom we were turning on. Wish list? Sure: a) it would benefit from more heat transfer wire in the “foot pockets,” & b) I’d be happier if they’d up the amps to deliver about 20% more heat on the “high/preheat” setting. That said, no regrets & a strong “buy” recommendation.

WORKS GREAT!!! LOVE IT
I hate buying electric heating products because you never know what you’re going to get. I have purchased quite a few heating pads over the years but Sunbeam products have always been the overall winner. I felt I could trust Sunbeam again while choosing a heated mattress pad. I have Reynauds disease and cannot sleep with cold feet. This high quality heated mattress pad is better than what I expected. I love it, I’m thinking of getting another just to have on hand. It has a multi leve, easy to usel heat control that gooes from low L, then numbered levels up to high. High gets too hot for me!! It heats up fast and has automatic shut off after 10 hours. I can’t tell youo about the WiFi option because I don’t use it. I am very pleased with this product. It’s well worth the price..

A Winter Must Have. Quick Heat and WiFi Connectivity
I really like this Sunbeam Mattress Heating Pad, especially at the price point. I upgraded from an older Sunbeam pad to the Sunbeam Connected Restful Quilted. This heating pad heats up much quicker and warmer than my old one. I like to pre-heat the bed and there is a feature for that, but I have not tried that feature yet. Level 5 for 5-10 minutes is plenty so far. The WiFi connectivity is convenient and was the main reason for my purchase of this model. However, connecting the WiFi took some patience and many retries (Unplugging the controller from the wall outlet). You will want the Sunbeam Bedding S2 app, there are two different Apps, at least on iPhone. Choose Bluetooth during initial setup instead of AP Mode. AP Mode didn't function. Once the App is configured it is easy to connect with Alexa. I use Alexa to turn it on before bed and to set an off timer. I took a "star" off for a couple of odd things, not deal killers at all. The connector is at the foot and on top, I can feel it with my feet. If you turn off the blanket with the App you have to wait a period of time before you can turn it back on with the App. Most of the time this is not a problem, but was an initial concern while testing during App configuration. Also of note there is only a single controller for both sides, which works perfect for me.

Sooooooooooo nice 👍
After doing bedtime for our children, my wife and I would joke about how terrible it was to get under our cold sheets and have that shock disrupt our ability to quickly get back to sleep. With this Bluetooth/programmable electric mattress pad, we schedule it to automatically turn onto Low at 8:30 pm and, like magic, warm bed awaits. I tend to run a bit warm at night, so I like that it lets me schedule to turn off after 1 hour while my wife keeps her side running until 6 am. Have had for maybe 3 months and would definitely buy again (and again and again).

Three Years of Warmth and Convenience: A Smart Sleep Solution
I've been using the Sunbeam Polyester Wi-Fi Connected Mattress Pad since 2021, and it continues to impress. Here's why: Convenient Preheating: The Sunbeam app allows me to preheat the bed before getting in, ensuring a warm and cozy start to the night. Morning Warmth: I schedule the pad to turn on in the morning as the house heats up, making it easier to get out of bed. Voice Control: Integration with Alexa adds hands-free convenience, allowing me to adjust settings without lifting a finger. Durability: After three years of use, the mattress pad remains reliable and effective. Overall, this mattress pad combines technology and comfort seamlessly, enhancing my sleep experience.

Only as smart as its constant Error message
I've had several heated mattress pads before. The first two were Beauty Rest, I think, and were wonderful - the first lasted 5 years, and the second was donated after 3 years of use. The last one was a Bittenford (sp. ?) - purchased when I switched from a queen to a king bed. That one only heated one side of the mattress and was a disappointment. I had high hopes for this Sunbeam, especially after the 1/2-heated bed. I was excited about the "smart" feature - first because I often forgot to turn the heat on before I crawled into bed, and second because I wanted to be able to decrease the heat while sleeping. Aside from the pad having a nice, soft top and the wires not being prominent (I always put a waterproof mattress pad on top), I've been less than impressed with this purchase. 1) Set up: I follow directions when they are understandable. These weren't too bad. However, the instructions direct to put the mattress pad on the bed before connecting it to wifi. This is probably fine if your wifi signal is strong throughout the house, but it's inconvenient if your bedroom happens to be in an area with limited range. It's even less convenient if you not only put the mattress pad on, but made up your entire bed. :/ It's not an entire pain to set up unless you have 5G wireless in your home (which so many of us do). I have 2.4 and 5G networks available, but have only used the 5G...which meant that I needed to set up the 2.4, which led to several other devices needing to be reset/reconfigured. 2) Error message: Because I had made up my bed after first putting the mattress pad on my bed, I opted to wait until the next sheet change to strip it and try again. I manually turned the mattress pad on every night but crawled into a cold bed 3 out of 6 of the nights. Every "cold sheets" night, the controller read "E" and I had no idea why. The power problem was solved by unplugging/re-plugging it, but I still went to bed in a cold bed. I hoped connecting the pad to wifi would help, and it has. I've only received "E" messages 3 times since I set it up (3 weeks), which IS an improvement...but still unacceptable. It's also quite annoying that the mattress pad needs to either be reconnected to wifi (which, again, is a pain if you need to move the mattress pad closer to the modem/router) OR re-scheduled every time it's unplugged - even for a second. If you accidentally knock the plug while re-making your bed, or are trying to find the perfect placement for the ONE control, or have to reset the pad because you receive another inexplicable Error message - your settings will be erased. 3) App control vs. physical control: You can set the physical control to "pre-heat" and it will automatically switch to whatever the last heat setting was after the pre-heat cycle. On the app, though, you're able to set it to pre-heat, but it doesn't revert to the last heat setting once the pre-heat cycle is done; it powers off. Also, if you set the mattress to anything above a "4" using the app, you need to adjust the physical control within an hour (a safety feature, I know) or it powers down to a "4". *Also, Sunbeam asks for user location, content, usage data, contact info, and identifiers (in addition to diagnostics, which is the only thing they should need). 4 )Heat Performance: It has 10 heat settings. I like to set it to High before bed, but it doesn't always feel like "high" when I crawl in. It's also not very warm at the feet, which seems like a zone that should be prioritized. 5) I believe Sunbeam deletes app reviews. When I first got the mattress and tried to set it up, I was frustrated and left a review to reflect that frustration. When I finally got it set up, I returned to update the review, but it was gone...As were several other reviews that I had read prior to leaving my own. I just checked again to make sure I wasn't mistaken, but I'm correct. My review is still missing. Bad business practices and subpar product.... I'll be looking for my BeautyRest again and find a smart plug or something. I'd recommend you do the same.

Great alternative to a heated blanket
My son is 8 and he loves to be warm and cozy. He gets under my electric blanket, he will sleep under me like a baby chick under a hen, and he hates to be chilly. He has fleece sheets on his bed (https://www.amazon.com/gp/product/B088SZ61GD) and a wool blanket (https://www.amazon.com/gp/product/B08KQ5H22B), but he wants the bed warm when he gets in it. I let him use my electric blanket, but he said he had to wake up to turn it down / off, and he wasn't getting a good night's sleep. I bought 2 of these (because his brother is 9 and has a bed, too) and they are great!! some people are having technical difficulties, so let me walk you through it: 1. Open the box and scan the QR code to download the SUNBEAM APP. While it is downloading, put the mattress cover on the bed. Ours have the plug at the head of the bed because that is where the outlets are. They are at the edge and are behind their pillows. They do not create a problem. 2. Setup an account on the Sunbeam app and connect the mattress controller to your phone via Bluetooth. Then name your bed. I just have Boone's Bed and Cubby's Bed. Create your schedule(s) if you want. 3. If you have Alexa, then go to the Alexa App, open Skills, and choose the Sunbeam skill. Enable it and sign into your Sunbeam account that you just created through the Alexa app to link them. Now you can say "Alexa turn on Cubby's Bed" and the bed will turn on. If the bed temp is set above 5, you will have to tap the checkmark on the bed control to confirm you want it on, so keep that in mind. That is it. Now just enjoy the even, gentle heat from your mattress pad!

2.5 stars
Pros: it’s warm. You can use an app to start it. It has one controller. Cons: when I turn it on using the controller, it’s SO HOT!!! Like scalding hot on the lowest temp. It does not do this when turning it on with your phone. If you set up a schedule in the app so it turns on at a certain time, you have to hit the check button on the controller within an hour or it shuts off. I had two schedules one to preheat the bed for an hour and a half and the second to turn to a low setting for 10 hours. Woke up FREEZING in the middle of the night because it shut off after an hour of the second schedule that I was already asleep for. I bought a queen. I would LOVE for a company to have two options for queen and king sizes. I sleep in the middle of the bed. I don’t want two separate sections. Anyway, aside from that, it’s big. I can feel it under my sheet and it causes my sheets to bunch up and move around with it. It’s loose and I have it tucked under my mattress on all sides. My mattress is a 16”.

Brilliant idea!
A wifi electric blanket might seem like overkill, but nothing beats coming home after a late night to a warm bed!

Must have for cold winters!
Must have for Canadian winters! This is my second one and we love it. I do not have any complaints with it. I preheat my bed remotely when I leave work, so when I am home the bed is nice and toasty. Which is lovely especially after a cold night shift. There is safety features so you have to physically press a button on the controller before 1hour is up so it doesn't stay on preheat or high all the time unattended. Bonus it can be paired with Amazon Alexa so you can control it with your voice. We have it setup so we can tell Alexa to preheat the bed.

Heats up very fast.
It works so well. The WIFI connection is thought was a bit of a gimmick. It works amazing and the safety feature does well. Thanks Sunbeam.
