If you're waking up sore, sleeping poorly, or noticing sagging, your mattress may need to be replaced. If your mattress still feels comfortable but the support underneath is failing, your box spring could be the issue.
Both mattresses and box springs wear down over time, and either one can affect how comfortable and supportive your bed feels. Understanding the signs of each can help you figure out what needs replacing so you can get back to better sleep.

Waking up in pain is often one of the clearest signs that your mattress needs replacing. As a mattress ages, it can lose its ability to support your body properly. When this happens, pressure points can develop that affect circulation and spinal alignment.
Common signs your mattress may need replacing include:
Your sleeping position also plays a role in how comfortable your mattress feels.
Back sleepers often benefit from medium-firm to firm mattresses that support the lower back. Side sleepers may prefer a medium-soft to medium-firm mattress that cushions the shoulders and hips. Stomach sleepers typically need a firmer mattress to help prevent pressure on the lower spine.
If you move between positions throughout the night, a medium-firm mattress is often the most versatile option.
If you're waking up tired even after a full night's sleep, your mattress may not be providing the comfort and support your body needs.
