Elevate Your Sleep with the Dumos 4-Inch Memory Foam Topper King

Rethink your mattress with a topper designed to cradle your body while adapting to your night-time needs. The Dumos topper adds a 4-inch memory foam layer to your existing bed, offering a balanced blend of softness and support without replacing the mattress itself. The result is a sleep surface that can feel more responsive to your movements and contours, helping you wake refreshed.

Smart design for targeted comfort

The 5-zone ergonomic support is engineered to target key areas from head to toe. This layout can help distribute weight more evenly, potentially reducing the feel of pressure on hips and shoulders. It’s suited for side sleepers and anyone seeking a consistently cushioned feel along the body’s length.

• 5-zone ergonomic support targets head, shoulders, hips, knees, and feet
• Memory foam contours to your body for cradling comfort
• CertiPUR-US certified foams for trusted materials and safety

Cooling gel for a refreshingly cool night

The cooling gel infusion works with the memory foam to absorb and dissipate heat, helping to keep the sleep surface breathable during warmer nights or restless periods.

• Gel infusion actively absorbs surface heat
• Breathable memory foam promotes airflow for a cooler feel
• Compatible with a range of room temperatures for steady comfort

Uninterrupted sleep with versatile support

The topper offers a reversible feel that blends a softer and firmer surface in one product, giving you two comfort options without layering extra toppers. This design aims to reduce tossing and turning and adapt to evolving comfort needs without adding bulk.

• 2-in-1 reversible soft and firm feel
• Balanced support across thicknesses for varied preferences
• May suit different sleeping positions without extra toppers

Multi-scene versatility

Designed to be practical beyond a traditional bed, it can revive sagging dorm mattresses, bolster firm RV bunks, or serve as a plush camping pad. Available in 2, 3, and 4-inch options to tailor breathability and support to your setup.

Whether it’s a dorm room, a road trip, or a guest bed, the topper adapts to different spaces while staying easy to move and set up.

Safe, sealed, and simple setup

Delivered in a sealed, compressed roll for compact handling. Unpack, unroll onto your mattress, and allow a few days for full expansion and any transit odor to dissipate, revealing a ready-to-sleep surface.
