Saatva has sent me two free toppers, both after I asked. The first came while my Saatva Classic was breaking in, and the second in December 2025.

From 2012 to 2016, I slept on an inexpensive memory foam mattress from IKEA, on IKEA slats. After four years, my back started aching all the time. The foam had changed too, with a dip and lumps by the end.

That’s when I started researching hybrid mattresses, the kind with innerspring and memory foam together. In 2016 I bought a full-size Saatva Classic, and the delivery guys took the IKEA mattress away. Another plus I love about Saatva is their white glove delivery.

The Classic went close to ten years with no dip I noticed, and we only let it go because the full was getting too tight once my wife was pregnant. Now we’re on a queen Saatva Memory Foam Hybrid.

If your own bed has started to dip or go lumpy like that IKEA one, it may be going the same way.

Which signs mean your mattress is actually worn out?

A dip or lumps that stay put mean the mattress is wearing out. They come from the soft layers on top breaking down, so you sink through toward the firmer core and the bed sags in places instead of holding you up.

Look for a body-shaped dent that’s still there after you get up, foam that’s shifted, or slats you can feel through the mattress. You might also catch yourself rolling toward the middle.

Run a hand across the bed and feel for sudden drops or soft spots, then measure any dip you find.

Waking up with a stiff or sore neck, back, shoulders or hips counts just as much.

To see if it’s the bed, spend a night or two somewhere else. If you sleep better at a hotel or a friend’s place, that’s a strong sign too.

Springs poking you, new squeaks from an innerspring, allergies or waking up hot can also come with a worn mattress. On their own they don’t settle it, so look for one of the strong signs alongside them.

How the bed feels tells you more than its age. If you’d still like a number, how long a mattress lasts has the usual years and which kinds of bed hold up longest.

If none of this sounds like your bed, it probably has some life left in it. Lucky you!

Why is it so easy to miss?

Because it happens a little at a time, and owners say it often took a new bed to show them how worn the old one was.

Until then you get used to it. A slow sag just starts to feel like your side of the bed.

What else could it be?

A new bed, a weak base or the wrong firmness can all feel like a worn-out mattress. Even a brand-new one can leave your back aching for the first few mornings, and owners say that can just be you adjusting.

The frame or base can let a mattress dip, too, so check what’s under yours before you blame the mattress itself.

And if you sleep on your side, a medium-firm mattress might simply be too firm for you.

What should you do about it?

Sagging? Check your warranty before you shop, because a dip that’s deep enough is the company’s to fix. Measure the dip and file a claim if it goes past the depth your brand covers.

Not ready to buy yet? A topper can make a shallow dip feel better for a while, but it won’t fix the sag, so think of it as a way to buy time before a new mattress.

When the strong signs are there and nothing above helps, it’s time for a new one, and I’d go with the same Memory Foam Hybrid as ours.
