## Description

The LUCID 4 Inch Bamboo Charcoal Memory Foam Mattress Topper brings you the benefits of memory foam pressure point relief combined with the odor and moisture control of bamboo charcoal. Bamboo charcoal has many great qualities: it eliminates odors, absorbs excess moisture, regulates temperature, and is an excellent choice for people with allergies. Combined with contouring memory foam, it is an innovative masterpiece. Bamboo charcoal is created from the bamboo plant. First it is burned at high temperatures, then it is ground into a fine powder. Finally, it is infused in our memory foam. Bamboo charcoal has been used in medications and skin care products, and is completely safe to use in fabric and bedding products. This topper is ventilated for superior airflow and temperature regulation.

Review: Extremely comfortable! - I love my extra firm mattress but lately I’ve started getting joint pain. Bought this memory foam topper and my joint pain is gone! Just had to trim the end of the mattress as it’s California King (my mattress is European King size which is 10cm shorter). Highly recommend this mattress topper!
Review: depends on room temp - hotter the softer colder the more support also gets warm after 25 degrees

## Questions & Answers

**Q: Why should I get a topper?**
A: Whenever your mattress is ready for a refresh, but your wallet isn’t, it’s time for a topper. Or if you wish your mattress is softer, or if you are in a dorm or renting—a topper is a great solution! Upgrade your bed without the hassle.

**Q: Will my topper come in a box?**
A: Yes! We make it easy. Lucid memory foam toppers come compressed and rolled in a box, are easy to move, and set up in seconds. Just unbox it and let it decompress for 24 to 72 hours before sleeping on it.

**Q: What are the benefits of bamboo charcoal infusions?**
A: Bamboo charcoal infusions help manage moisture and may create a more hygienic sleep space. It also helps regulate odors for a fresher sleep environment.

**Q: What height topper should I get?**
A: The 2-inch profile adds a soft layer of support to your mattress. The 3-inch profile is very plush and adds even more comfort. The 4-inch profile is almost like a mini mattress, with an extra deep, plush feel, sink-in feel.
