DUMOS Full 3" Dual-Layer Gel Memory Foam Mattress Topper — Bamboo Rayon Pillow Top, Cooling Support

DUMOS Full 3in Dual Layer Gel Memory Foam Mattress Topper combines a 2" gel memory foam base with a 1" bamboo rayon pillow top to add cushioning, cooling, and pressure-relieving contour to an existing mattress.

Swap a too-firm or aging mattress surface for a softer, cooler sleep layer without buying a new bed. This DUMOS topper uses a gel-infused slow-rebound memory foam foundation and a breathable bamboo-derived rayon pillow top to improve comfort, airflow, and surface temperature for a variety of sleep positions. It ships vacuum-packed and expands after unrolling.

How does this topper change mattress feel at night?

The two-layer construction softens an overly firm surface while still offering supportive contouring. The slow-rebound memory foam molds to body curves to reduce concentrated pressure, and the plush pillow top adds an immediate cloud-like surface.

• 2" gel memory foam base for gentle contouring and distributed support
• 1" bamboo rayon pillow top for a softer initial touch
• Overall 3" thickness for noticeable change in mattress feel
• Suitable for side, back and stomach sleepers who want extra cushioning

Will this topper help keep me cooler during sleep?

The topper is designed with temperature-conscious materials: cooling gel in the foam and a breathable bamboo-rayon cover that wicks moisture. Together they promote airflow across the surface and speed heat dissipation compared with plain foam or thick fabric covers.

• Gel-infused foam helps draw heat away from contact areas
• Bamboo-derived rayon top offers a silky, moisture-wicking surface
• Ventilated design encourages airflow to reduce trapped warmth

How does it stay in place on my mattress?

DUMOS includes a deep-pocket elastic skirt that secures the topper to mattresses between about 8" and 16" thick. The fitted skirt minimizes shifting during the night, making it compatible with most innerspring, foam and hybrid mattresses.

• Elastic deep-pocket skirt for snug fit on 8–16" mattresses
• Designed to reduce sliding and bunching through movement
• Easy to install—wraps like a fitted sheet around the mattress

What materials and safety standards are used?

The topper combines CertiPUR-US certified memory foam with an OEKO-TEX Standard 100 bamboo rayon cover, offering a fiberglass-free and non-toxic construction. It arrives compressed and vacuum-packed; allow 48–72 hours in a ventilated room for full expansion and odor dissipation.

• CertiPUR-US certified gel memory foam for low VOCs and safety
• OEKO-TEX Standard 100 bamboo rayon pillow top for soft, tested fabric
• Fiberglass-free construction and responsive customer support

Who this is for: The DUMOS Full 3in Dual Layer Gel Memory Foam Mattress Topper fits sleepers who want to soften a too-firm mattress, improve surface cooling, or refresh a guest bed without replacing the whole mattress. It works well for couples seeking improved pressure distribution, hot sleepers preferring breathable surfaces, and anyone who wants a simple, secure upgrade that fits 8–16" mattress depths. Follow unpacking guidance for best expansion and let the topper air out before first use.
