The bed that
grows with you.
And them.
Castaway is the first motorized split king bed that opens in the middle, revealing a hidden center platform for a bassinet, a growing toddler, or everything you'd rather not keep on the floor. Two Twin XL mattresses. One king surface. A room that stays a bedroom.
Nobody designed a bed
for real life with kids.
We did.
Every parent figures it out the hard way. A bassinet squeezed to one side. One person handling the night. A nursery down the hall that turns every wake-up into a full reset.
Castaway was built for those early years, and everything that comes after. Two Twin XL platforms glide apart on demand, revealing a concealed center space that's always been there. It's space for a bassinet, a pack-and-play, or the small mountain of diapers, wipes, bottles, and burp cloths that somehow takes over your nightstand in those first months. No wobbly side tables, no extra stands crowding your bed, and no reshaping your entire room around temporary gear. As your kids grow past the bassinet years, that same space becomes a shared middle surface, so you keep your room, your bed, and your sanity.
- ✕ No more one parent handling every wake-up alone
- ✕ No more balancing bottles and wipes on the edge of your nightstand
- ✕ No more defaulting to the couch just to get through the night
- ✕ No more choosing between closeness and actual sleep
The wakeup you know by heart.
Now it happens at arm's reach.
The bed only moves
when you tell it to.
Every parent asks us about this, and honestly, they should. Before you put any piece of furniture anywhere near your kids, you want to know exactly how it works and what could possibly go wrong. So here's the short version, no sensors that could malfunction, no software that could glitch, just a simple push-to-operate switch that keeps you in control of the entire bed, every second it's moving.
Push-to-operate switch.
The bed only moves while you're actively holding the switch down, which means it cannot open or close unless a person is actively holding the switch the entire time. There's no timer, no remote, no app, and no voice command that could ever get the motor running on its own.
Stops the second you stop pressing.
The bed doesn't need to finish what it started, and it doesn't keep moving once you let go. If you stop pressing three seconds in, the bed stops three seconds in, and it stays exactly where it is until you decide what to do next. That goes both ways, opening and closing.
Slow, controlled, and impossible to miss.
It takes about seventeen seconds for the bed to open fully, which is intentional. The motion is slow, steady, and deliberate, and because the bed is driven by a real motor, it makes an audible sound while it's running. You'll know when it's moving, it's not something that happens silently.
Safety is the part we care about most, so we wrote a full breakdown of how Castaway is designed, tested, and meant to live in a bedroom with kids and pets.

your family grows.
From the early days with a bassinet within reach, to the toddler who always ends up in the middle, to the years when you get your bed back, Castaway adapts without needing to be replaced.
Their bassinet, between you. At arm's reach from both parents.

needed at 3 a.m., built in.
You tried the bassinet-beside-the-bed thing. You tried the bedside sleeper. The solution was never another accessory, it was the bed itself.
Both parents, equal access.
A bassinet in the middle keeps both of you within arm's reach, instead of one parent handling every wake-up alone.
Room for the middle kid.
Once they're past the bassinet stage, they have a defined space between you, not sideways across your pillows.
Opens in about 17 seconds.
Slow, smooth, intentional motion. Operated by a push-to-operate switch, the bed only moves when you tell it to.
Your room stays your room.
No extra furniture crowding the room. Your bedroom doesn't have to become a second nursery to function for your family.
Two mattresses, your way.
Twin XL on each side means you and your partner each get your own surface, without compromise.
Becomes a king. Seamlessly.
Closed, Castaway creates a unified king sleeping surface. Guests would never know it opens.
Push-to-operate.
That's it.
Castaway uses a single push-to-operate switch, housed behind the nightstand. The motor only runs while you're holding the switch, so the bed can't move on its own, and can't be activated by a curious toddler from the mattress.
Clear the surface.
Before operating, check that the bed surface is clear of objects, pets, and people. We recommend operating with the lights on.
Press and hold.
The push-to-operate switch is behind the nightstand, out of a toddler's reach. The bed only moves while the switch is held down; release, and motion stops instantly.
Center platform, revealed.
About 17 seconds of slow, smooth, intentional motion to fully open the bed and reveal the hidden center platform that sits beneath the two Twin XL beds. The same switch closes it again. The beds glide back together into one king surface.
For your newborn, use a bassinet.
Castaway's hidden center platform sits lower than the bed surface, which can accommodate a legless bassinet placed on top, bringing it closer to your level.
For infants, we always recommend sleeping in a certified bassinet or bedside sleeper that meets current safe-sleep guidelines, never directly on any mattress surface.
Instead of placing the bassinet on one side of the bed, it can be placed between both parents, with each within reach. As your child grows and no longer needs a bassinet, the center surface becomes a shared middle space.
Infants sleep in a bassinet.
Place a legless, safe-sleep-compliant bassinet or bedside sleeper on the center platform. Never place an infant directly on any mattress surface.
Older children can share the middle.
Toddlers and older children who are past safe-sleep age can rest on the center platform between both parents.
Operate with a clear, visible surface.
Always check the bed is clear of people, pets, and objects before using the push-to-operate switch. The bed only moves while the switch is actively held.
Follow pediatric safe-sleep guidance.
For newborns, follow guidance from your pediatrician and the American Academy of Pediatrics. Castaway is a bed frame, not a sleep product for infants.
"I would have killed for a product like this when my daughter was little. Those first months were a blur of a bassinet wedged beside the bed, a nightstand buried in diapers and wipes, and a bedroom that stopped feeling like mine. I kept thinking there had to be a better way to set up a room during this stage of life. There wasn't. So years later, we built one."
Good ones.
