Meet the FATHOM Firm Twin Mattress, a precision-engineered 8-inch memory foam bed designed for everyday comfort in compact spaces. Shipped in a box for convenient setup, it expands to a twin size that fits a wide range of frames and foundations. Built to deliver balanced support and a cool sleep surface, it aims to keep you comfortable through wide temperature swings and nightly movement.

Advanced Cooling Comfort: The AeroFusion gel memory foam layer is designed to promote breathable performance. It adapts to your body’s curves while helping dissipate heat, so you can feel cradle-soft support without a hot, stuffy surface. The result is a sleep surface that tends to stay cooler through the night, even during warmer seasons.

• Breathable memory foam contours to your shape while promoting steady airflow
• Cooling properties help reduce nighttime heat buildup for a more comfortable rest

Removable Fiberglass-Free Cover and Easy Care: The top surface features a fiberglass-free design and a cover that can be removed for cleaning. This simplifies maintenance and helps keep the sleep space feeling fresh with routine washing or spot cleaning as needed.

• Fiberglass-free design reduces concerns about exposure in the sleep area
• Removable cover enables straightforward cleaning and refreshes the surface

CertiPUR-US Certified Materials: The foams in this mattress meet independent standards for content, emissions, and durability. This certification provides reassurance about materials used in daily sleep, without heavy chemical odors or harsh additives.

Designed for Twin Spaces and Everyday Use: The 8-inch profile is practical for guest rooms, small apartments, or shared bedrooms where space matters. Memory foam layers promote even weight distribution, potentially reducing pressure points and helping you settle into a more relaxed rest across the surface.

• Twin size that pairs well with most frames
• Memory foam contouring supports a variety of sleeping styles

Care and Sleep Experience: Upon unboxing, allow the mattress to fully regain its shape before regular use. The removable cover supports easy cleaning, and the overall design emphasizes a calm, supportive surface without aggressive odors. While results vary by individual, many sleepers appreciate the blend of support and cooling comfort for nightly routines and weekend resets.
