Memory Foam Mattress 12 in Twin Medium Firm - Pressure Relief

Our review of this 12 in medium firm memory foam mattress finds it best suited for someone who wants balanced support with a cooling feel without the bounce of innerspring designs. The mattress combines 3 in of gel memory foam, 2 in of comfort support foam and a 7 in flex comfort base to deliver a medium firm feel that conforms to different sleep positions. The single biggest reason to buy is the pressure-relieving gel layer that helps reduce shoulder and hip pressure while the breathable cover and wave-shaped support layer improve airflow for a cooler night's rest.

Key Features

• Layered construction: The 3 in gel memory foam over supportive foam layers contours to body curves for even weight distribution and pressure relief.
• Medium firm feel: A combination of foam thicknesses provides a balanced firmness that works for side, back and stomach sleepers.
• Certified foam and cover: The mattress uses CertiPUR-US certified foam and an OEKO-TEX Standard 100 cover to reduce exposure to certain harmful chemicals.
• Breathable cover and airflow layer: A wave-shaped support layer and knitted cover improve ventilation to help dissipate heat and odors faster.
• Removable cover: A bottom zipper allows the cover to be removed for cleaning, extending the usable comfort of the mattress.
• Compressed-in-box delivery: The mattress ships rolled for easy moving and expands to full size within about 72 hours.

Who It's For

This mattress is a sensible choice for dorms, guest rooms or a primary twin bed where balanced support and pressure relief matter. It particularly suits sleepers who want the hugging feel of memory foam but need firmer backing for spine alignment during back or stomach sleeping.

Those who prefer a very plush, pillow-top feel or who need extra edge support for heavier body types should look elsewhere. Also, if immediate full loft is required, know that it can take up to 72 hours to fully expand and for any transient odor to fade.
