Niagara Sleep Solution King Ultra-Soft Mattress Topper — Bamboo-Rayon Cover, Cooling Plush 78×80

If your mattress feels too firm or traps heat, this king-size topper blends 7D hollow and 3D fine fibers with a rayon cover derived from bamboo to create a plush, breathable surface. It delivers a cushioning layer that reduces pressure points and promotes a cooler night’s rest for hot sleepers. The topper ships compressed for convenience, is machine-washable, and carries OEKO-TEX STANDARD 100 certification for textile safety.

How does the topper change the feel of my firm mattress?

The Niagara king topper adds a pillow-top layer that softens firm surfaces to reduce sharp pressure on shoulders and hips. It produces a cloud-like surface without altering mattress support dramatically, so the underlying support system still works as designed.

• 78 × 80 in king size covers the whole mattress surface
• 600 GSM / 83.0 oz filling blends 7D hollow with 3D fine fiber for loft
• Rayon-derived bamboo cover provides a silky, gentle hand
• Preserves mattress support while adding cushioning

Will this topper keep me cooler if I run hot at night?

The bamboo-rayon cover and the lofted fiber fill increase airflow compared with dense foam, helping heat dissipate faster. While not an active cooling device, the materials are sweat-absorbent and designed to feel cooler to the touch and move moisture away from skin.

• Breathable 7D hollow + 3D fine fiber core lets air circulate
• Rayon from bamboo cover is moisture-wicking and soft
• Lightweight loft reduces trapped heat versus memory foam

How easy is it to fit, maintain, and care for the topper?

The topper includes an elastic skirt designed for deep-pocket mattresses from 8 to 21 inches so it stays in place. It’s machine-washable and retains its properties through repeated laundering when cared for per instructions.

• Deep-pocket skirt with extra-length stretch fits thick mattresses
• Machine-washable; maintain shape with low-heat tumble if needed
• Ships compressed — shake, pat, and allow 48 hours to fully loft

What materials and certifications should I be aware of?

The cover is 300 thread count rayon derived from bamboo with a 150 GSM elastic skirt. The fill is a 600 GSM blend of hollow and fine fibers. The product is OEKO-TEX STANDARD 100 certified, indicating it meets textile safety limits for harmful substances.

• 600 GSM / 83.0 oz fiber fill: 7D hollow + 3D fine fiber blend
• 300 TC bamboo-derived rayon cover and 150 GSM elastic skirt
• OEKO-TEX STANDARD 100 No. 15.HCN.57692 certification
