Review: 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!

## Questions & Answers

**Q: The “Do’s and Don’ts” guide says not to lay on top of it but it’s a fitted mattress pad. Can we talk about that?**
A: Hello Amazon Customer, 

The item is designed to be used with a fitted sheet over the mattress pad.  It is not designed to be used without it.   Thank you.

**Q: Does it come with a 5 year or a 3 year warranty? One description says 5 and the other one says 3.**
A: The manual in the package says 3.  That last one I had was at least 10/11 years.  I bought a new one because it had been washed so many times, the seams started to fray.

**Q: Does it have a cooling feature?**
A: No it does not have a cooling feature

**Q: How do you turn it off? I know this is a silly question, I just do not see anything indicating it is off, or how to except for using the timer**
A: The same button that turns it on will turn it off. It is hard to tell in the dark but you will see the number go away if you press it again. Or you can set the timer.

### ⭐⭐⭐⭐⭐ Good purchase
*by A***R on March 7, 2026*

It is SO nice to get in to a warm bed on a cold night. Not since I owned a heated water bed has bedtime been so pleasant, I only need the low heat setting. I like to start the heater a half hour or so before bedtime. The controller allows me to have the heat turn off during the night, after I have the bed up to my normal temp.
