We have a king size mattress. But the bedframe is longer than the mattress. I’m not entirely sure what happened, but I wish I would’ve seen a review that said that. Because it’s too long, there’s a gap either at the foot of the bed, or at the head of the bed. Meaning our stuff falls through the cracks of the head of bed. It’s incredibly annoying, mostly because it’s our pillows that go first. When we had our boxspring and our mattress on the bedframe, it was entirely too tall. So now we are facing buying a shorter boxspring to make it somewhat better. It’s a great bedframe, but it’s just too long, I wouldn’t have ever thought of measuring it when it said it was a king size bedframe on the website. ￼￼
