You've probably heard the term 'rocking' when people talk about mattresses, and it can sound a bit… well, wobbly. But in the world of mattress testing, it's actually a pretty important indicator of how a bed handles movement. It's not just about how much it bounces, but how much of that movement transfers across the surface.
When our team at U.S. News & World Report was putting mattresses through their paces for our 2026 mattress guide, we paid close attention to this. We had testers in our lab, getting a feel for each bed, and we also gathered insights from over 1,400 readers who'd been sleeping on these mattresses long-term. It's this combination of hands-on testing and real-world experience that really paints the full picture.
For instance, in our testing, we noted that some mattresses, like the Brooklyn Bedding Signature Hybrid, had testers feeling "bigger movements rocking the mattress." Now, that might sound like a negative, right? But it's all about context. This particular bed, which we ended up naming our Best Overall mattress, also boasts "strong support and overall testing scores." So, while there might be a noticeable transfer of motion, it doesn't necessarily detract from its overall performance, especially when you consider its affordability and the fact that it offers three firmness levels to suit different sleepers.
What we're really looking for when we talk about 'rocking' or motion transfer is how disruptive it is. If you share a bed, you don't want to be jolted awake every time your partner rolls over. Different mattress types handle this differently. Foam mattresses, for example, tend to absorb motion better than some hybrid or innerspring models. But even within hybrids, there's a huge range of performance.
It's a delicate balance. You want a mattress that offers support and comfort, but you also don't want it to feel like a rigid board. That slight give, that ability to cradle you without sinking too far, is what makes a mattress feel good. The trick is finding that sweet spot where you get the responsiveness you need without excessive motion transfer. It’s why we look at a whole suite of factors, not just one isolated characteristic, to determine what makes a mattress truly great.
