How do I know if my mattress is affecting my sleep?

Key signs include waking with back, hip or shoulder pain that wasn't there at bedtime, sleeping noticeably better elsewhere, visible sagging or indentations in the surface, feeling the springs through the mattress, and waking more frequently than usual without a clear reason.

How long does a mattress last?

Most mattresses last between seven and ten years. Memory foam tends to last slightly longer than innerspring models. After eight years, it is worth assessing whether the mattress is still providing adequate support, even if it still looks acceptable on the surface.

Can an old mattress cause back pain?

Yes. A mattress that has lost its structural support can allow the spine to fall out of alignment during the night, leading to lower back pain, hip stiffness or shoulder discomfort that is most noticeable in the morning and eases as the day progresses.

What firmness of mattress is best for sleep?

It depends on your sleep position and body weight. Side sleepers generally benefit from a softer surface that cushions the shoulder and hip. Back sleepers typically do better with medium-firm support. Most people find that medium or medium-firm works well as a starting point.

Will a new mattress fix my sleep problems?

A new mattress can help if physical discomfort or poor support is contributing to disrupted sleep. However, it will not resolve sleep difficulties caused by other factors such as stress, hormonal changes or a nervous system that struggles to settle at night. These may need to be addressed separately.

Is Your Mattress Ruining Your Sleep? Signs It's Time to Change

Sleep

When sleep gets worse, most people look inward. Stress, hormones, too much screen time, not enough exercise. These are all worth considering. But there's one factor that rarely comes up in the conversation — and it's been under you every night for the past decade.

Your mattress has a significant effect on sleep quality, and an old or unsuitable one can cause problems that are easy to mistake for something else entirely.

How Long Should a Mattress Last?

Most mattresses have a lifespan of seven to ten years, depending on the material and how they're used. Memory foam tends to last slightly longer; innerspring mattresses typically start to degrade sooner. After this point, the structural support begins to break down even if the surface still looks fine.

If your mattress is over eight years old, it's worth asking whether it's still doing its job — regardless of how it feels when you first lie down.

Signs Your Mattress May Be Affecting Your Sleep

None of these signs alone is conclusive, but several together are a strong signal.

You wake up with aches that weren't there when you went to bed. Lower back pain, stiffness in the hips or shoulders, or a neck that takes an hour to settle in the morning — these can all point to inadequate support during the night. A mattress that's too soft allows the spine to fall out of alignment; one that's too firm creates pressure points that build over several hours of stillness.

You sleep better elsewhere. If you wake up feeling noticeably better after a night in a hotel, a guest bedroom, or even on a sofa, that's useful information. It suggests the problem is the sleeping surface, not your sleep itself.

You can feel the springs. Any sensation of the internal structure through the surface of the mattress means the comfort layers have compressed beyond the point of usefulness.

The mattress sags or has visible indentations. A dip of more than an inch or two in the area where you sleep most is a clear sign the support is gone. This is particularly common in the centre of the mattress and along the edges.

You wake more frequently than you used to. Discomfort that isn't quite enough to fully rouse you can still pull you out of deeper sleep stages, leaving you feeling unrefreshed even after a full night. This kind of fragmented sleep is difficult to trace back to a mattress because you may not remember waking at all.

You've noticed increased allergy symptoms at night. Older mattresses accumulate dust mites, which are a common trigger for nighttime congestion, sneezing and skin irritation. If symptoms are worse in bed than at other times of day, the mattress is worth considering.

What to Look for When Choosing a New One

Replacing a mattress is a significant investment, and the market is overwhelming. A few principles help narrow it down.

Support and comfort are not the same thing. Support refers to how well the mattress keeps your spine aligned; comfort refers to how the surface feels. A mattress can feel soft and still provide good support — or feel firm and create pressure points. You need both working together.

Your sleep position matters. Side sleepers generally need more cushioning at the shoulder and hip. Back sleepers typically do better with medium-firm support. Front sleepers — though it's not ideal for the spine — need a firmer surface to prevent the lower back from arching.

Body weight affects feel. A medium mattress will feel firmer to a lighter person and softer to a heavier one. Trial periods (most reputable brands now offer 100 nights or more) exist precisely because it's impossible to know how a mattress will perform until you've slept on it for a few weeks.

Don't overlook the base. A good mattress on a worn or unsuitable base will underperform. Slatted bases should have gaps of no more than seven centimetres; solid bases suit most mattress types but may reduce airflow.

Mattress or Something Else?

It's worth being honest: a new mattress won't fix sleep that's being disrupted by something systemic. If you're waking repeatedly, struggling to fall asleep, or lying awake for long stretches, the surface you're sleeping on is unlikely to be the only factor.

Sleep quality — particularly after 50 — is often affected by how well the nervous system transitions into rest. Tension that doesn't release at bedtime, a mind that won't settle, or a body that stays in a low-level state of alertness through the night are patterns that go beyond the mattress.

Vitalisys Sleep Patches support that transition using a botanical blend of lavender, hops, cedarwood and jasmine, delivered through the skin across the night. They work alongside good sleep hygiene — including sleeping on a surface that actually supports you.

The Short Version

If your mattress is over eight years old, shows visible wear, or you consistently wake with aches or feel better sleeping elsewhere, it's worth replacing. Pair that with attention to what else might be affecting your nights — and you'll be addressing the problem from both directions.
