The topper combines a 2 in cooling gel memory foam layer with a 2 in quilted pillow top cover to create a 4 in buffer that aims to relieve pressure and reduce back pain. It is best for side and back sleepers who value a cloud-like surface with medium firm support and for anyone who wants an adjustable layer they can remove or combine for personal comfort.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 In 1 adjustable dual layer design:\u003c\/strong\u003e The separate 2 in gel memory foam and 2 in pillow top allow users to use one or both layers to tune overall thickness and support.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling gel memory foam:\u003c\/strong\u003e The gel-infused foam provides contouring support while attempting to limit heat retention compared with standard memory foam.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuilted breathable pillow top:\u003c\/strong\u003e The pillow top uses snow down alternative overfilling for a soft, cloud-like initial feel that cushions shoulders and hips.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree dimensional fiber structure:\u003c\/strong\u003e 3D and 7D fibers in the pillow top promote air circulation to reduce trapped heat and increase comfort.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable, washable cover:\u003c\/strong\u003e The 400 TC combed fiber topper cover is machine washable and designed to withstand regular cleaning without ripping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-year warranty and easy setup:\u003c\/strong\u003e Vacuum packed for shipping with a recommended 48-72 hour expansion time and a decade of warranty support.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe MASVIS dual layer topper is ideal for adults who sleep on their back or side and need extra pressure relief around the shoulders, lower back, and hips; it works well for those who want a hotel-like plush surface without sacrificing support.
