Split King: The Best of Both Worlds for Couples
Tired of fighting over mattress firmness or sleep positions? The Split King bed offers the perfect solution for couples who want shared space without sacrificing individual comfort. By combining two Twin XL mattresses side by side, a Split King delivers customizable support—while still feeling like one big bed.
Whether you need different firmness levels, want to reduce motion transfer, or plan to use an adjustable base, this setup could be your sleep dream come true.
📏 Split King Bed Dimensions
A Split King is made by placing two Twin XL mattresses (38″ x 80″) side by side, creating the same total dimensions as a Standard King.
- Width: 76 inches (193 cm)
- Length: 80 inches (203 cm)
- Shape: Rectangular (same as Standard King)
- Split: Vertically down the middle
This configuration fits King-size frames and headboards, but the mattress surface is divided into two.
🧍🏼♀️🧍🏻A Sleep Divorce-Friendly Bed Option
More and more couples are trying something called sleep divorce—choosing to sleep separately for the sake of better rest. But sleeping apart doesn’t always mean separate rooms.
The Split King bed is one of the best sleep divorce solutions for couples who want their own space without giving up the shared bedroom. Each person gets their own mattress with their own settings, yet you can still be close enough for connection.
If you’re dealing with:
- Snoring
- Different bedtimes
- Tossing and turning
- Conflicting comfort preferences
… a Split King allows you to customize your sleep without the emotional distance.
