3 Inch King Memory Foam Mattress Topper with Cooling Cover — Open-Box, 21% Off

SOFT PLUSH CUSHIONING WITH ADJUSTABLE STRAPS & NON-SLIP BOTTOM: Take the hard edge off a too-firm bed with a generous 3-inch layer of plush memory foam that eases pressure on your shoulders, hips, and back with a contouring sink, so side and combination sleepers wake up feeling less stiff. Adjustable corner straps and a non-slip bottom keep it securely in place through the night, and the flexible foam bends easily with adjustable bases for comfort that holds its position.

BREATHABLE COOLING COVER, REMOVABLE & WASHABLE: A soft, breathable cooling cover wraps the topper and unzips for machine washing, so everyday care takes minutes; please spot clean the foam only and never put it in the washing machine. Slip the clean cover back on and your King bed feels fresh again, with added softness and no mattress

ADVANCED COOLING GEL & VENTILATION: Stop sleeping hot. Our topper features an open-cell, ventilated design with cooling gel infusions that channel heat away from your body. Unlike standard foam that traps heat, our gel-cooling technology is a long-term feature designed to maintain its temperature-regulating properties for years of cool, breathable, and restorative rest.

OEKO-TEX SAFETY CERTIFIED & FRESH UNBOXING: Sleep safe with a topper that is both CertiPUR-US and OEKO-TEX Standard 100 certified. What is OEKO-TEX? It is a global certification ensuring every thread and foam component is tested for over 350 harmful substances, making it safe for your skin and your family. Any initial "fresh foam" scent is non-toxic and will fully dissipate within 24–48 hours of unboxing in a well-ventilated room.

48-HOUR EXPANSION & MATTRESS PROTECTION: Your King topper arrives compressed for easy shipping; simply unbox and allow 24–48 hours for it to fully expand to its plush 3-inch thickness. This high-quality barrier also protects your mattress from wear, tear, and sagging, extending its lifespan while providing the luxury feel you deserve from CGK Linens.

Upgrade your bed with plush, pressure-relieving comfort using this 3-inch gel-infused memory foam mattress topper with a removable cooling cover. This is a true topper, not just a replacement cover; it adds a thick layer of gel memory foam on top of your existing mattress, unlike a thin mattress pad that mainly protects the surface. Designed for sleepers who prefer a softer, more cushioned feel, this topper adds an extra layer of comfort to firm or worn mattresses without the need to replace your bed. The soft memory foam helps create a plusher sleep surface that feels more inviting night after night, making it a great choice for side sleepers and anyone who wants added softness and pressure relief around the hips, shoulders, and lower back. The CertiPUR-US certified foam is tested for content, emissions, and durability, and the high-density foam is built to hold its shape and resist flattening over time. A breathable cooling cover helps create a fresher, more comfortable place to rest, while the removable, machine washable design makes everyday care simple; the cover unzips and washes easily, while the foam itself should be spot cleaned only. Adjustable corner straps and a non-slip bottom help keep the topper more securely in place and reduce shifting through the night, and it is compatible with many adjustable beds. Because it adds about three inches of height, we recommend a deep-pocket fitted sheet for a smooth fit. Please note this topper ships compressed in a box; once unrolled, allow it to expand in a well-ventilated room, and any slight new-foam scent will fade within about 72 hours. A simple way to refresh your mattress with soft gel memory foam comfort, a cooling washable cover, and a more secure fit for better everyday sleep.
