Secgo King Mattress Topper — 100% Waterproof Bamboo-Rayon, 1000GSM Plush Support & Deep-Pocket Fit to 21"

Secgo’s Premium 100% Waterproof King Mattress Topper is a breathable bamboo-rayon mattress pad with a waterproof bottom layer and 1000GSM 3D filling that upgrades comfort and protects mattresses up to 21" deep.

Replace or refresh your mattress without the expense of buying a new one: this Secgo topper combines a soft rayon-from-bamboo surface, air-channel vents, and a leakproof base to add plush support, moisture management, and reliable protection. The design balances cushion and support using a 1000GSM 3D Snow Down filling while fitting securely on deep mattresses from 8" up to 21".

How does this topper handle spills and accidents?

The topper uses a full-coverage waterproof barrier on the bottom side to block liquids from reaching the mattress. Liquids are stopped at the base while the top layer remains soft and breathable for comfort.

• 100% leakproof bottom layer prevents liquid seepage into the mattress
• Waterproof protection covers the entire underside, not just edges
• Top fabric stays soft and absorbent; only the bottom is waterproof

Will it keep me dry and comfortable through the night?

The top panel is rayon made from bamboo with a patterned weave and added air vents to promote airflow and wick away light moisture. It enhances comfort for most sleepers but does not provide active cooling for extremely hot sleepers.

• Breathable rayon-from-bamboo surface with visible air vents
• Moisture-wicking fibers move perspiration away from skin
• Not a cooling-specific model—choose Secgo cooling lines for heavy night sweats

What kind of support and feel does the 1000GSM filling deliver?

The 3D Snow Down filling is engineered to create a soft-yet-supportive comfort layer that accommodates side, back, and stomach sleepers. It adds cushioning to reduce surface pressure while offering enough structure to preserve mattress responsiveness.

• 1000GSM density for a balanced soft-firm feel
• 3D construction helps maintain loft and even fill distribution
• Designed to promote neutral spinal alignment and surface pressure relief for many sleepers

How secure and easy is the fit and care?

Elastic skirt and deep-pocket construction fit mattresses from approximately 8" to 21" firmly to reduce shifting. The topper is machine washable for routine care; follow low-heat or air-dry recommendations to keep materials soft and loft stable.

• Deep-pocket skirt fits 8"–21" mattress depths snugly
• Machine-washable; avoid high-temperature drying and high-speed spin
• Designed to stay in place and retain softness over repeated washes

Who is this for? The Secgo Premium 100% Waterproof King Mattress Topper is aimed at sleepers who want to protect an existing mattress from spills while adding cushioned support and breathable comfort. It fits deep beds, families seeking a chemical-safe option, and anyone wanting an easy mattress refresh without replacing the mattress. If you sleep extremely hot, consider Secgo’s cooling-specific models instead.
