Main highlights

•The Leading Name in Mattress Toppers: Viscosoft is consistently recognized for the highest quality memory foam and innovative fabrics, offering luxurious sleep solutions for every budget and bed size — including harder-to-find sizes like Full XL.
•Upgrade the Comfort of Any Full XL Mattress: Whether you're outfitting a college apartment, preparing a guest room, or upgrading a basic full-size mattress, the Viscosoft Select High Density Full XL Mattress Topper adds exceptional comfort and support. Its longer length is ideal for taller individuals who want to stretch out without sacrificing support at the edges.
•Stay Cool Through the Night - Breathable Gel-Infused Foam: Shared apartments and dorm rooms often lack personalized temperature control, making sleep uncomfortable. Our gel-infused memory foam pulls heat away from the body, optimizing airflow to keep you cool all night—even in small, stuffy spaces.
•Tailored for Full XL Beds – Secure Fit & Easy Care: The Full XL topper stays firmly in place thanks to adjustable elastic straps and a slip-resistant base—no shifting, bunching, or sliding. The removable, machine-washable cover makes it easy to keep your bed fresh and clean year-round.
•Effortless Setup – Sleep Better In Minutes: Whether you’re moving into a new apartment, prepping for guests, or refreshing your current mattress, this topper sets up in minutes. It arrives compressed with a pre-fitted cover and stays snugly in place so you can enjoy an instant comfort upgrade with zero hassle.
•Durable, Long-Lasting Comfort – No Valleys or Sagging: Unlike low-density alternatives that compress over time, our high-density memory foam topper retains its shape and support year after year. It resists sagging, cratering, and flattening — even with nightly use.
•Trusted & Backed by a Satisfaction Guarantee: Proudly based in Charlotte, NC, Viscosoft stands behind its toppers with a 60-Day No Hassle Reimbursement Guarantee. Shoppers trust us to provide better sleep while away or in a new home.
•Reinforced Edge Support – Stay Supported from Center to Side: The reinforced edge-support foam provides stability whether you're sitting, lounging, or sharing the bed. No more sinking at the sides — just consistent comfort from edge to edge.
•Diverse Size Selection - As a leader in mattress toppers, Viscosoft offers products in a variety of sizes to enhance comfort in as many beds as possible. Along with options that perfectly fit all standard bed sizes, the Full XL accommodates evolving campus needs, futons and short-term rental owners that have placed this size bed in their properties to accommodate the diverse needs of their guests. The Twin XL is ideal for college dorms and split king beds, the Queen Short is designed for RVs and campers. This selection underscores our commitment to delivering a better way to great sleep to as many as possible.
