Split king and split cal king
A split king is two Twin XL SBKD3 bases side by side, so each sleeper controls their own side. A sync cable lets both halves move together when you want, and connecting straps keep them from drifting apart. Use two Twin XL mattresses, or one king split-top mattress.
Will it fit my bed frame?
The SBKD3 fits inside most standard bed frames, or sits directly on a platform or slats thanks to its zero-clearance design. Head- and footboard brackets are available as an add-on. Measure the inside of your frame and text John at 805-617-6878 if you are unsure.
SBKD3 or something fancier?
Want massage, USB charging and an under-bed light? Look at the SBKDP2. Want the base to glide toward the wall, or lumbar support? See the SBKDG2 Glide and SBKDL2 Lumbar on the adjustable base comparison chart. Lost your remote? We also carry the SBKD3 replacement remote.
Pair it with a mattress
Memory foam and hybrid mattresses flex best on an adjustable base. Popular SBKD3 pairings: the 12" ActiveAlign Reactive Copper Zoned and the 12" Copper, or save with a sleep system package.
