How Often Should You Replace Your Mattress?

The short answer is 7–10 years for most mattresses. The longer answer depends heavily on how it's built, how much weight it supports, and how well you've taken care of it. Some mattresses are ready for the curb at year six; some hybrids and latex beds are still going strong at year twelve. Here's how to tell where yours falls — and how to know when it's actually time.

How long each type lasts, honestly

• Innerspring: 5–7 years. Coils lose their bounce first, comfort layers wear second. The oldest and shortest-lived construction still on the market.
• All-foam: 6–8 years. Body impressions deepen over time and eventually stop rebounding — that's the failure mode.
• Hybrid: 8–10 years. Pocket coils and quality foams are the most durable combo for typical budgets.
• Latex: 10–15 years. The longest-lived option by a wide margin, which partly justifies the higher upfront cost.

These are ranges for a mattress used by a single average-weight adult with a proper foundation and a protector. Cut those numbers by roughly 20% for a couple, especially if there's a big weight difference, or for anyone over about 230 pounds. Cut by another 10–20% if you skipped the protector or use a sagging foundation.

The five signs it's time

1. You wake up sore or stiff — and it fades within an hour of getting up. This is the tell. Consistent morning soreness that resolves after you're out of bed is almost always a mattress problem, not a body problem.
2. You sleep better away from home. Hotel beds, guest beds, even the couch — if you consistently wake up feeling better anywhere other than your own bed, that's your body telling you.
3. There's a visible dip, sag, or body impression. Sight down the mattress from the foot of the bed with the sheets off. If you can see a depression where you sleep, the mattress is past its useful life.
4. You can feel individual coils or hear new noises when you shift. That means the padding above the coils has compressed and the coils themselves are starting to loosen.
5. Allergies flare up in bed. Old mattresses accumulate dust mites, dander, and mold spores in quantities that can trigger nighttime allergies even in people who don't have them during the day.

The 'is it broken or is it my body?' test

Spend two nights on a different bed — a well-made hotel bed, a guest room, a friend's spare room. If you wake up meaningfully better on the different bed, your mattress is contributing to the problem. If you wake up the same or worse, something else is going on — a pillow issue, a stress issue, an unrelated injury — and a new mattress won't fix it on its own.

How to make a mattress last longer

• Use a mattress protector from day one. Prevents most of what breaks a mattress early.
• Rotate 180 degrees every three months for the first year, every six months after.
• Use a proper foundation with slats no more than 3 inches apart, or a solid platform. Sagging foundations kill mattresses.
• Don't sit on the edge of the bed as a chair. It compresses the edge coils or foam in one spot.
• Keep pets off, or at least use a heavy quilt on top to catch the extra dander and oil.

What to do with the old one

Most mattress companies offer haul-away with a new purchase — take them up on it. If not, check your municipality's bulk-pickup schedule or a mattress recycling program. Over 75% of a mattress by weight is recyclable (steel, foam, cotton, wood), but almost none of that gets recovered if the mattress goes to a normal landfill. States like California, Connecticut, and Rhode Island run funded recycling programs; ByeByeMattress.com lists drop-off sites nationwide.
