Lavayoo XL aka Monstrosity is my wife's FAVORITE HEATING PAD. It is HEAVY, coming in at 10 pounds. This one is not for your kids or for your lovely granny. It will literally keep your bed warm under blankets for over 6 hours. 

More lava sand = more thermal mass = heat lasts longer...Its Science!

It is the first one she goes to 90% of the time. It provides a quick and easy way to soothe aches, pains, stress, and anxiety. They are perfect for migraines, back pain, neck pain, sore muscles, stiffness, poor circulation, cold feet, and more.

Just like any other heating or cooling pad, you can place your Lavayoo in the microwave or freezer for fast relief. What sets Lavayoo apart is the filling: odorless, ultra-rare lava sand—not food—so it lasts longer and stays clean.


Use Instructions

Heating:

  • Microwave: Heat for approximately 4 minutes to 5 minutes. Most microwaves work well at this time, but you may need to adjust slightly to suit your preference. Do not exceed 6 minutes.

  • Oven: Place on a cookie sheet to keep it clean. Heat at 200°F for 20–30 minutes. You may increase the heat slightly for faster warming, but avoid overheating—skin can burn at around 150°F.

Cooling:

  • Place the pad inside a sealed plastic bag to keep out freezer odors. Freeze for 2-3 hours, or store in the freezer so it’s always ready for use.

Washing:

  • Lavayoo pads can be washed by hand or in the dishwasher if needed, unlike food-filled heating pads. Watch this video to learn.

  • Dishwasher: Place on the top rack and run a normal cycle.

  • Drying: Place on a cookie sheet in the oven at 200°F for about 1 hour or until completely dry. Fine sand particles may come through the fabric; simply dust them off.

In Case of Damage:

  • The lava sand lasts forever, but the fabric may wear out over time. Replacement bags are available for purchase. Simply transfer the sand to a new bag and:

    • Sew it shut if you have a sewing machine, or

    • Use the included fabric glue to seal the opening.

  • You can also repurpose an old pair of jeans: cut off a leg, glue the ends, and create a new bag for free! Watch this video to learn how.

These Bamboo Pillowcases Made Me Realize I Sleep Hot
Color: 07 - Cream, Size: Queen (20" X 30"), Color: 07 - Cream, Size: Queen (20" X 30")
I bought these mostly because I kept hearing people talk about bamboo pillowcases and honestly thought it sounded a little overhyped, but I totally get it now. The first thing I noticed was how cool they felt compared to regular cotton. I tend to get warm when I sleep and flip my pillow a million times during the night looking for the cold side, and these actually stay noticeably cooler longer. They also feel really soft without having that weird slippery texture some silky pillowcases have. My skin has been less irritated lately and my hair definitely looks less frizzy in the mornings. I have thick hair that tangles easily overnight, and these have helped more than I expected. Another thing I appreciate is that they’ve washed well so far. I was worried they’d pill or lose softness after a wash cycle, but they still feel smooth and nice. They also just make the bed feel cleaner and more comfortable overall. One of those small upgrades that ends up making a bigger difference than you’d think.
