Questions about beds and mattresses answered. And some stories told.

One-Piece King Adjustable Bed vs. Split King Adjustable Bed

When choosing an adjustable bed in King size, you’ll come across two main options: the one-piece King and the split King. Each has distinct benefits and trade-offs, and the “better” choice really depends on your sleep preferences, bedroom setup, health considerations, and budget.

Definitions

• One-Piece King Adjustable Bed
  A single adjustable base paired with a single King-size mattress. Both sides of the bed move in unison, so any adjustments affect the whole sleeping surface.
• Split King Adjustable Bed
  Two separate Twin XL (or comparable) adjustable bases placed side by side, each with its own mattress. Together, they create the same footprint as a King bed, but each sleeper has independent control over their side.

When a One-Piece King May Be the Better Choice

• You and your partner share very similar sleep preferences—for example, you both like the same incline, mattress firmness, and head/foot positioning.
• You prefer a continuous, seamless sleeping surface with no split down the middle.
• You’re working with a tighter budget, since one-piece Kings tend to be less expensive than split Kings.
• You don’t expect to use many independent adjustments (e.g., both of you usually sleep flat or both want the same head elevation for reading/watching TV).

When a Split King May Be the Better Choice

• You and your partner have different sleep needs, such as differing firmness levels or medical considerations (acid reflux, sleep apnea, circulation issues, snoring).
• You want independent adjustability, so one person can raise the head of the bed while the other lies flat.
• You’re sensitive to motion transfer—movements on one side of the bed are much less likely to disturb the other sleeper.
• You want a bed that’s easier to move and set up, since it comes in two separate bases rather than one large, heavy unit.
• You’re comfortable with a higher upfront cost, and potentially spending more on specialty bedding or accessories.

General Drawbacks to Consider (Both Types)

• Cost: Adjustable beds are generally more expensive than non-adjustable traditional beds.
• Maintenance: They contain motors, wiring, and remotes, which means more parts that could fail over time. A strong warranty is essential.
• Bedding Fit: Standard sheets may not stay snug during adjustments; stretchy or specially fitted bedding often works better.
