The high-density NXG Memory Foam provides balanced contouring that adapts to all sleep positions. Medium feel offers enough cushioning for side sleepers' pressure points while maintaining sufficient support for back and stomach sleeping, creating versatile surface for combination sleepers who change positions.
The 5-zone hybrid coil system features alternating firm and plush areas that accommodate different sleep positions. Provides support beneath lumbar region for back sleepers, cushioning for side sleepers' shoulders and hips, and prevents excessive sinking for stomach sleepers. BestEdge Support maintains stability from edge to edge, maximizing sleeping surface.
The CoolFeel Cover provides cool-to-touch surface that delivers immediate cooling sensation when you lie down, helping you fall asleep faster. The fabric dissipates body heat for comfortable initial contact with mattress surface.
The Carbon Fiber Memory Foam layer actively draws heat away from body throughout the night. Carbon fiber's thermal conductivity pulls warmth from sleep surface and disperses it, maintaining comfortable temperature. This dual cooling approach combines immediate surface cooling with sustained heat dissipation for all-night comfort regardless of sleep position.
Use mattress protector to guard against stains. Rotate head-to-foot every three to six months for even wear. Avoid jumping or standing on mattress. Do not fold or bend. Allow new mattress to air out for 24-48 hours after unboxing.
Medium firmness balances support and cushioning to accommodate side, back, and stomach sleeping. Provides enough cushioning for side sleepers' pressure points while maintaining sufficient support for back and stomach positions. Ideal for combination sleepers who change positions throughout the night.
Medium offers middle-ground versatility. Plush (2500) provides more cushioning specifically for side sleepers while firm provides maximum support for stomach sleepers. Medium balances both, making it best choice for combination sleepers or couples with different preferences who need one mattress that works for everyone.
Yes, the medium feel accommodates different sleep preferences and positions. Motion control design minimizes partner movement impact while balanced firmness works for various body types and sleeping styles. NXG Memory Foam and 5-zone coils provide individualized support, making it excellent for couples with different preferences.
The medium feel adapts as you move between positions. NXG Memory Foam responds to your body in each position while 5-zone coils provide targeted support whether you're on your side, back, or stomach. This versatility makes medium ideal for combination sleepers who don't stay in one position.
