Fold the extra large heat pad in to 3 sections. Microwave the heating pad on a clean plate, flip after a minute, and then one more minute. The wrap is heavy. It can take longer to heat up. The wrap is also moist and takes time to heat up initially. This will all improve after repeated use.
Drape it over the neck, shoulder, tummy, back, arm, leg, or anywhere that needs attention. Use directly against the skin for better heat benefit.
Do not exceed 3 minutes of total heating time.
Freeze in a plastic bag for 2 hours.
How to clean: remove the cover and machine wash it. Do not wet the bladder filled with seeds. The seeds will stick together and the wrap can become unusable.

Size 10" x 24" x 1".
Weight: 4 lbs
Fill: US-grown human-grade flax seeds
Fabric: washable anti-pill fleece as the cover and 100% cotton as the bladder cover

Great for warmth in lower back area.

I bought this for my wife, as part of her birthday present. She already has several stuffed animals she warms in the microwave. It is difficult to have warmth in the lower back area with the stuffed animals.This product solves that problem very well.

Sam

Best Body wrap ever!

I purchased the body wrap several years ago and love it so much I ordered a second for my husband. It gives such relief to my back, shoulders, leg from Fibromyalgia. My gastro recommended I sleep with it across my stomach and it's been a huge help! It's like being wrapped in a warm hug! I Highly recommend this company and received a handwritten thank you with my order!

June Spradlin

Relieves back pain

I use this heat pad every single day after work. I stand all day and by the time I get off work I can hardly walk. I use this pad and it does bring alot of relief and makes it easier to fall asleep. Highly recommend!

Betty White

Perfect for back or shoulder pain

I suffer lower back pain and periodic pain in my right rotator cup. I have a few cold devices and heating devices but after I received the SunnyBay Store Reusable Pure Enrichment Heating Pad it's become my go to heating pad. The pad is 10 inches by 24 inches and covers a rather large area. Simply put it in the microwave and turn it on. The temperature will be dependent on how long you leave it in. I usually do 45 seconds to a minute. Of course you don't want to overdo it with the time. I either lay on my stomach and put it across my lower back or I lay on top or it. For my shoulder I drape it right over it and lay back. If you have neck pain you can wrap it like a shawl around your neck. The pad retains heat for around 20 minutes then begins to cool down. I'll throw it in the microwave for another 30 seconds to keep treating my pain. Although I use it for heat you can also put it in the freezer and use it as a cold compress. I use the pad every single day since receiving it.

Trevor Jerry

Versatile and Comfy!

Love this product! It is great for your neck, lower back, glute area. I usually use this the next day after my workout, the fabric feels comfortable against the skin and provides such a thorough relief in well needed areas. I also was able to order it in my favorite color purple which came out to be super cute. 10/10. Would definitely recommend to others!

Multiuse heating pad. Easy to use.

This heating pad is so cozy. The material is Avery soft almost blanket like material. It is easy to use and very diverse. You can use it for your neck, back, stomach (during the time of the month), feet, etc. The weight and the heat makes it super comfortable and relaxes your muscles. I really enjoy the leopard print as well. Worth the price.

Good for readers!

I'm an avid reader but often I get uncomfortable reading on my back so I lay on my side or prop up on my stomach. This works well until I go to move and have a crick in my neck from holding my head at an odd angle! I pop this in the microwave and then lay it across my neck and it really relieves the pain and it stays put while I read in one of my many positions! It's also soft and very comfortable!
