10 reviews for Serta Waterproof Heated Mattress Pad in White, King ST55-0118

  1. Janice M

    I recently replaced my old heated blanket with this one, and I’m glad I did. It’s waterproof, which is perfect for sleeping with pets, and it heats up much better than my previous one.

  2. Kathleen O

    This heated sheet is amazing! It keeps my bed warm during the winter and helps alleviate my body aches, especially from my previous ankle injury. It’s a lifesaver after a long day of manual labor.

  3. Dorothy M

    We are satisfied with this mattress pad that effectively keeps my husband warm, although it can become too hot on settings higher than “1”. We consistently use it on the lowest heat setting.

  4. Phyllis M

    After a delay in delivery, I received the product and immediately tested it by placing it on my bed and turning it on. The heat setting has a maximum of 10.

  5. Alicia R

    After switching from a heated blanket to this heated mattress pad, I am extremely satisfied with the consistent and adjustable heat levels, with level 4 being my personal favorite. I highly recommend this brand for anyone looking for a reliable and comfortable heating option.

  6. Michele A

    This product heats up quickly and I found that setting it to “1” provides the perfect temperature for a comfortable night’s sleep. Despite my initial concerns about the wires, I cannot feel them at all when lying on it. Additionally, the light turns off immediately after pressing any button.

  7. Jennifer H

    I absolutely adore this luxurious product! It quickly warms up my bed and has a timer that automatically shuts off after an hour, without any issues. I am truly in love with it!

  8. Kathleen C

    This heated mattress pad has many great features, including comfort, warmth, and easy-to-use controls with multiple heat levels. However, I did experience a design flaw with the cord plugging in at the bottom, and the cloth on my previous one fell apart. Thankfully, it was still under warranty, but it was still inconvenient.

  9. Lavelle P

    After experiencing issues with my electric blanket and a lack of heat in my house, I decided to look into heated mattress pads. I was pleasantly surprised by the results and found that the pad provided more consistent and comfortable warmth compared to my previous blanket.

  10. Mary L

    After 3 months of use, this product is still performing well. However, the lowest heat setting is slightly warmer than desired, with a maximum of 10 settings.
