Luxurious thick mattress pad is crafted with 1000gsm ultra snow down alternative filling, which is twice as much as traditional mattress topper. The filling is evenly distributed, which disperses body pressure and prevents sagging, providing a five-star hotel-like level of comfort. - Enhance Sleep Quality, If your mattress is too firm or if you are suffering from sleep problems and waking up with back discomfort, adding our mattress topper cover is an excellent solution. It will provide softness and comfort to old and hard foam mattresses, relaxing your body quickly and allowing you to experience a deeper and more restorative sleep. Say hello to waking up feeling energized and ready to conquer the day. - Super Soft & Fluffy, The mattress topper full incorporates a tight weaving technology and has a 50% 3D+50% 7D gold filling ratio. This ensures that the fibers can stretch more easily in a box-shaped three-dimensional structure, keeping the mattress cover fluffy and soft with a cloud like feel. Enjoy a long sleep without any loss of support. - Deep Pocket & No-Slide, The full bed mattress pad is 54x75 in size, featured a stretchable deep pocket ranging from 8 to 23 inches, which allows it to perfectly wrap your mattress. It can be easily placed on most mattresses, enabling you to turn over freely on quiet nights without any noise or worries about the movement of the mattress. - Cool Feeling & Sleep Well, The cooling microfiber topping material provides a refreshing sensation. By adding 50% virgin cooling microfiber into the fillings, the full size mattress pad allows for better airflow, ensuring comfortable and breathable sleep. The improved air circulation prevents night discomfort and overheating and maintain a balanced body temperature throughout the night. - Worry Free Service & Care Instruction, Machine-washable mattress toppers will save more energy and time. We advise leaving the mattress topper for several hours before use, or tumble drying it on low heat to fluff it up faster. Please feel free to contact us, and we will make every effort to solve any problems. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C8HZDG3X | | Age Range Description | Adult | | Best Sellers Rank | #9,001 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #34 in Mattresses Toppers | | Brand | Kayfia | | Brand Name | Kayfia | | Closure Type | Pull On | | Color | White | | Customer Reviews | 4.4 out of 5 stars 3,330 Reviews | | Fabric Type | Surface Layer, Bottom Layer, Filling, and Pocket – 100% Polyester | | Item Firmness Description | Soft | | Item Highlight | Overfilled Plush Pillow Top, Soft and Breathable Cover, 8–23'' Deep Pocket, 54x75 Inches, Machine Washable | | Item Type Name | Mattress Pad | | Manufacturer | Kayfia | | Manufacturer Part Number | 1 | | Material Type | Polyester | | Model Name | MP-900 | | Model Number | 1 | | Number of Items | 1 | | Number of Packs | 1 | | Other Special Features of the Product | 8-23" Deep Pocket Protector, Back Pain Relief, Boxing Quilted, Washable, Breathable, Cloud-Like Soft | | Product Care Instructions | Machine Wash | | Size | Full | | Special Feature | 8-23" Deep Pocket Protector, Back Pain Relief, Boxing Quilted, Washable, Breathable, Cloud-Like Soft Special Feature 8-23" Deep Pocket Protector, Back Pain Relief, Boxing Quilted, Washable, Breathable, Cloud-Like Soft See more | | Thread Count | 900 | | Unit Count | 1 Count | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** Kayfia - **Color:** White - **Fabric Type:** 100% Polyester - **Size:** Full - **Special Feature:** Breathable, Cooling, Deep Pocket, Pillow Top, Washable ## Images ![Full Mattress Topper, Thick Mattress Pad for Back Pain Relief, White - Image 1](https://m.media-amazon.com/images/I/71AyoruhPpL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The BEST!!!!
