Alaskan King Bed: The First Week Setup and the Decision That Matters Most

The box spring corners scraped the hallway wall before we even got it into the bedroom. That sound—drywall losing to compressed wood—is still in my head. But that's not the part you need to plan for. The part that actually decides if your week goes smooth or sideways is the mattress decision. And most people get it wrong.

The Alaskan king is huge. Like, 9 feet by 9 feet huge. That's not a typo. It's basically a California king with an extra foot in every direction. You can't just walk into a mattress store and grab one. You have to order it, and the delivery guys will hate you. But more on that later. First, the layout.

The Room Measurement That Saves You from Returning It

Get the tape out. Don't trust your eyes. An Alaskan king needs a room that's at least 14 feet by 14 feet if you want any path around it. I have a 12x14 bedroom and after the bed went in, I had about 18 inches on each side. That's enough to shuffle, not enough to open a dresser drawer fully. If your room is smaller, think about that before you order. I've seen people try to squeeze an Alaskan king into a 10x10 and they end up having to climb over the footboard to get out of bed. Not a joke.

Also, measure your doorways. The bed frame comes in pieces—the headboard, footboard, side rails—but the box spring or foundation? That's got to go through the door. We had to stand ours on its side and almost took out a light fixture. If you live in an apartment with narrow hallways, check the path from the street to the bedroom. Because once it's in, it's not going back out without a lot of swearing.

The one decision that matters most? Getting the right mattress setup. The Alaskan king is so big that most people opt for a split mattress—two twin XLs or a custom split. That way you can move each half separately. And if you and your partner have different firmness needs, split makes sense. But don't scrimp on the connector. The gap between two twin XLs can turn into a chasm if you don't get a bridge or a quality mattress topper. Spend the money.

Unboxing and Getting It On the Frame

The first night we slept on ours, the frame creaked. Not a gentle groan—a full-on squeak that woke me up every time I rolled over. Turned out we hadn't tightened the bolts enough. Torque them snug, then go another half turn. Loctite is your friend. And if you can, assemble the frame before you put the mattress on—much easier to tighten bolts when you can actually see them.

Another thing: the mattress itself is heavy. I mean, each half of a split king weighs about 130 pounds. If you're assembling alone, you'll hate every minute. Bring a friend or two. And don't be embarrassed to use the furniture sliders under the bed legs once it's in place—because you might need to move it an inch, and that's not an inch you'll push using your back.

The Biggest Surprise: Sheet Shopping

You can't just go to Target. Regular sheets won't fit. King deep-pocket fitted sheets are too small. You need Alaskan king sheets, and they're not cheap. We paid more for the sheet set than we did for some of the furniture in our living room. And if you have a mattress that's extra thick, watch the pocket depth. You might need to go custom. That's a hassle, but having to pull a corner sheet back up at 3AM is worse.

First Week Check: The One Decision That Really Matters

So here's the thing that will make or break your first week: the mattress firmness. Because a bed this big, you can't just flip it or swap it easily. We got a medium-firm split, and I still wonder if we should have gone softer. If you have any back issues, think about a split with an adjustable base. We didn't, and I regret it. You can't upgrade the base without lifting the whole mattress off and starting again.

Also, the room will get warmer. An Alaskan king traps heat. We ended up switching to a lighter comforter. That first week, we woke up sweating even with the AC on. Not ideal.

So if you're reading this because you're about to order one, slow down. Measure. Think about the split. Plan the delivery. Don't skip the base mistake article—that's a real fix. And when the truck shows up, have cash for the guys who carry it in. They'll deserve it.

One last thing. The first time you climb into a bed that's nearly the size of a small country, you'll feel ridiculous. And that's the right feeling. Because it's practical only if you have the space. If you don't, you'll know by week two, when you've developed a bruise on your hip from catching the corner of the dresser every night. Nobody needs that.

We're keeping ours, but only because we made the right choices the first time. Go read If Your Room Is Tight, Read This on Bed Shop before you hit checkout.
