Avocado Green Tight Top Split King Mattress with Head Up Only Base

Yes, this mattress is exceptionally well-suited for temperature regulation. It is constructed with organic wool and cotton, which are naturally moisture-wicking materials that draw heat and perspiration away from the body. Because it avoids polyurethane and synthetic foams—which are known to trap heat—this hybrid design promotes airflow through the coil system and latex layers, helping you maintain a cool, dry sleep environment even in warmer coastal or southern climates.

A split king setup is the ultimate solution for partners with different sleep preferences. Unlike a standard king, which moves as one unit, this configuration consists of two separate Twin XL mattresses. This allows each person to independently control the head-up feature of their side using the wireless remote, ensuring one partner can sit up to read or alleviate snoring without disturbing the other's flat sleeping position.

To ensure the mattresses can move independently on the adjustable base, you will need a split king sheet set. This typically includes two Twin XL fitted sheets (one for each mattress) and a single King-sized flat sheet and pillowcases. We recommend choosing sheets with deep pockets and high-quality elastic to ensure they stay securely in place when the head of the mattress is elevated.

This mattress utilizes GOLS-certified organic Dunlop latex, a material renowned for its buoyant and responsive nature. Unlike synthetic foams that can create a "sinking" feeling, this latex cradles the body while providing immediate pressure relief. Furthermore, the internal support system features 1,379 individually wrapped coils arranged in seven patented zones, specifically engineered to provide ergonomic support to the shoulders, hips, and lower back.

Elevating the head is a common recommendation for managing symptoms of acid reflux, GERD, and snoring. By using the RTG Sleep 2900 adjustable base to raise the mattress, gravity helps prevent stomach acid from rising and keeps airways more open. This "head-up" functionality allows for precise positioning to find the most therapeutic angle for your specific health needs.

A "tight top" mattress features a firmer, more responsive surface compared to the thick, plush layers of a pillow top. This design is ideal for sleepers who prefer a more supportive feel and easier movement in bed. The absence of extra padding on top also makes it a durable choice, as it is less prone to the sagging or body impressions that can sometimes occur over time with softer materials.

Because a split king consists of two independent mattresses placed side-by-side to allow for individual movement, a small seam is necessary. To minimize the feel of this gap, this mattress is hand-tufted in up to 24 locations. This traditional artisan technique binds the layers securely without the use of chemical glues, creating a more stable, uniform sleeping surface across the edges of each mattress.
