A split king bed combines two twin XL mattresses that come together to form a king-size bed. You may want a split king bed if you and your sleep partner have different firmness preferences or general sleep differences. Any two EGO Twin XL mattresses can be used in a split king sleep system.
Purchase a split king sleep system, select your EGO twin XL mattress. Add your mattress selection to the online shopping cart. Change the mattress quantity to (2). Follow the same process for your adjustable base selection -- add a base to the online shopping cart and change the quantity to (2).

Ensure your mattress is supported by a firm, flat foundation such as a foundation box, semi-flex box spring, or platform bed with adequate slats less than 2” apart. A foundation using slats more than 2” apart will cause memory foam to become wavy. If your current foundation has any dips, sags, or soft spots, it might be time for a replacement! We recommend platform beds or an adjustable base to receive the best performance from your mattress.
