What Is a Split King Adjustable Bed?
A split king adjustable bed is two Twin XL adjustable bases placed side by side inside a king-size bed frame. Each base has its own motor, remote, and controls — meaning each partner can adjust their head and foot elevation completely independently.
The dimensions work out perfectly:
| Configuration | Width | Length |
|---|---|---|
| Standard King | 76" | 80" |
| Split King (2x Twin XL) | 76" (38" + 38") | 80" |
Same total size, but with the massive advantage of independent control. This is why split king has become the most popular adjustable bed configuration for couples.

Split King Adjustable Bed Buying Guide
Split King vs. Standard King Adjustable Bed
The biggest decision when buying a king-size adjustable bed is whether to go split or standard. A standard king adjustable base uses one motor system — both sides move together. This is cheaper (you only buy one base) but means any adjustment affects both sleepers. A split king uses two independent bases, so each person controls their own side. If you sleep alone or always want the same position as your partner, standard king saves money. For couples with different sleep habits, split king is almost always worth the extra cost.
Total Cost: What to Budget
A split king setup requires two bases and two Twin XL mattresses. Here's what to budget:
- Budget split king: $950-$1,100 (two bases)
- Mid-range split king: $1,100-$2,000 (two bases)
- Premium split king: $3,200-$4,000+ (two bases)
- Add $400-$2,000 for two Twin XL mattresses (varies widely)
Dealing with the Middle Gap
The #1 concern about split king beds is the gap where the two mattresses meet. In practice, this gap is typically 0.5-1 inch and most couples adapt quickly. If it bothers you:
- Mattress gap filler: A foam wedge insert that bridges the two mattresses ($20-40)
- King-size topper: A 2-3 inch memory foam topper across both mattresses unifies the surface while still allowing independent adjustment
- Connector straps: Keep the bases snug against each other to minimize separation

Sheets and Bedding for Split King
Standard king sheets will NOT work on a split king — they can't accommodate independent movement. You need either two sets of Twin XL fitted sheets or purpose-made split king sheet sets (which have separate fitted sheets but a shared flat sheet and comforter). See our guide on the best sheets for adjustable beds.
