About this item

  • [Product includes] Contains 36 pieces of moisture-proof gaskets that can be spliced ​​(single piece size: 11.8 inches × 11.8 inches), which can be easily assembled into a complete cushion layer of 83 inchs × 83 inches, perfectly matching the queen-size bed of the RV, seamlessly fitting.
  • [Dry and Lasting] Moisture is easily accumulated between the RV mattress and the bed board, breeding condensation water. This product uses a scientific lifting design to form an air circulation layer at the bottom of the mattress, effectively blocking moisture, saying goodbye to the musty smell, and making sleep more refreshing and comfortable.
  • [High-quality Material Selection] High-density environmentally friendly plastic material, with both flexibility and strong load-bearing capacity (over 3,000 pounds), moisture-proof and pressure-resistant, lightweight and durable, no tools are required for installation, and it can be assembled and used.
  • [Multi-functional Use] It is not only a moisture-proof tool for RVs, but can also be used in scenes such as motorhomes, yachts, and campers to solve the problem of moisture in sheets caused by temperature difference/humidity, and protect sleep dryness in multiple scenes.
  • [Usage Tips] Newly unpacked products may have a slight plastic smell. It is recommended to place them in a ventilated place for 1-2 days before use. The smell will dissipate naturally and will not affect the use effect.
