A split top air adjustable mattress is a mattress designed for adjustable bed bases that allows each sleeper to raise or lower the head of their side independently while still sharing a single mattress.
When it comes to sharing a bed with a partner, finding the perfect sleep setup can be challenging. You might prefer a firmer mattress while your partner likes it soft. You might want your head elevated for reading, while they want to lie flat. This is where split top air adjustable mattresses become game-changers. For a full overview of air adjustable technology, see our air adjustable mattress guide. For a comparison with split king setups, see our split king guide.
What is a Split Top Air Adjustable Mattress?
A split top air adjustable mattress features a unique design where the top portion (typically from the waist up) is divided into two separate sections, while the bottom remains one piece. This allows each partner to adjust their side's firmness independently, raise or lower their head position without affecting their partner, and maintain a unified mattress appearance without a visible split down the middle.
Unlike traditional split king mattresses that are completely separated, split top designs keep the foot of the bed together, preventing the annoying gap in the middle. Also see our split top vs split head comparison to understand the difference.
Why Split Top Mattresses Are Perfect for Adjustable Bases
Independent Head Adjustment
Each person can raise or lower their head section independently. This is perfect when one partner wants to read or watch TV while the other sleeps, someone needs elevation for acid reflux or breathing issues, you have different preferences for zero gravity positioning, or one person snores and needs head elevation.
Customizable Firmness on Each Side
Air adjustable technology means each partner controls their side's firmness level — from soft to extra firm with the touch of a button. Change firmness as your needs change during pregnancy, injury recovery, or aging. See our mattress firmness guide for help choosing your starting point.
Unified Foot Section
The connected foot section means no gap in the middle for sheets to fall through, easier bed-making with standard king-size sheets, and a more intimate sleeping arrangement than fully split mattresses.
Choosing Between 10" and 14" Split Top Options
Beverly Hills Bed offers split top air adjustable mattresses in two thickness options. See our air mattress thickness guide for a full breakdown of how thickness affects comfort and support.
10" Split Top Air Adjustable Mattress
The 10" split top air adjustable mattress is perfect for couples who want a lower-profile aesthetic, easier bed entry and exit (great for those with mobility concerns — see our seniors guide), a firmer more responsive feel, and budget-friendly premium sleep technology.
14" Split Top Air Adjustable Mattress
The 14" split top air adjustable mattress delivers luxury-level comfort with maximum cushioning, a high-end hotel-quality aesthetic, extra support for heavier individuals, and enhanced pressure relief for chronic pain or joint issues.
Real-Life Scenarios Where Split Top Shines
The Reader and the Sleeper
One partner can raise their side to a comfortable reading position without disturbing the other's sleep — especially useful when paired with wallhugger technology that keeps you close to your nightstand.
The Snorer Solution
When one partner snores, elevating the head can significantly reduce snoring. With split top design, only the snorer's side needs to be elevated. See our zero gravity guide for more on how elevation reduces snoring.
Health Condition Management
For couples where one person has acid reflux, sleep apnea, or circulation issues requiring elevation, split top mattresses allow for therapeutic positioning. See our best adjustable bed positions for back pain for more positioning strategies.
How Split Top Works with Adjustable Massaging Bases
When paired with dual adjustable massaging bases, split top air mattresses create the ultimate personalized sleep system with independent massage controls, separate positioning (zero gravity, anti-snore, or custom positions), wireless remotes, preset positions, and under-bed lighting. See our adjustable bed frame features guide for a full breakdown of available features.
Making the Bed: Easier Than You Think
Use standard king-size fitted sheets (the unified foot section makes this possible). For the best fit, look for deep-pocket fitted sheets if you choose the 14" option. See our bedding collection for compatible options.
Investment in Better Sleep Together
Split top air adjustable mattresses eliminate the compromise that often comes with sharing a bed. No more meeting in the middle on firmness, no more disturbing your partner when you adjust positions, and no more sleeping in separate rooms. Compare with the Sleep Number comparison to see how our split top technology stacks up.
Perfect for Different Life Stages
Split top air adjustable mattresses adapt to your changing needs: pregnancy (adjust firmness and elevation as your body changes), injury recovery (customize support during healing), aging (easier bed entry/exit and therapeutic positioning — see our seniors guide), and weight changes.
