Something wrong with your mattress? Let’s sort it out.
Four quick steps. Check it, measure it, photo it, send it. We take it to the maker for you.
In short: A Modern Mattress warranty is for defects in how your mattress was built, for up to 10 years depending on the collection (M Series: 5 years). Firmness at first, shallow dips and a hump in the middle are normal; keep the law tag on, and the maker makes the final call on every claim.
What do you see?
Tap the one that sounds like your bed.
Showroom beds have had lots of guests on them, so they feel softer. Yours is brand new, and your body is used to your old bed. About 3 weeks to get used to it, about 90 nights to fully settle in. Give it at least 21 nights.
What to expectMany dips are normal. If it is 1.5 inches or deeper with nobody on the bed, it could be a claim. The maker reviews every claim and makes the final call.
Is it normal?An edge that collapses with no weight on the bed can be a warranty claim. Lay a straight edge along it, measure the gap, then send it to us. The maker reviews every claim and makes the final call.
How to measureA broken or poking coil can be a warranty claim. Take a close-up of the spot with the other photos, then start your claim. The maker reviews every claim and makes the final call.
The photosA seam coming apart, not from damage, can be a warranty claim. Take a close-up with the other photos, then start your claim. The maker reviews every claim and makes the final call.
The photosStains, spills, burns and tears are not manufacturing defects, and a stain can void the warranty. A protector from day one keeps it clean.
Protect itThe feel is what our 100-night comfort exchange is for, with one exchange between nights 21 and 100.
Comfort exchangeFirm at first, then fitted to you.
Like a new pair of leather shoes. It starts firm, and every night it shapes to you.
Give it at least 21 nights. Your body is adjusting too.
Shallow dips are normal.
NormalYour comfort layers fit to your body. That leaves a soft dip where you sleep. Light body impressions under 1.5 inches are normal, not a defect.
A hump in the middle? Also normal.
Normal wearTwo people, two sides. Your sides do all the work, and the middle barely gets used, so it stays firmer. That is the hump. It can happen on any King, and it is normal wear.
The easy fix: sleep in the middle.
Firm middleSleep here too- Sleep in the middleA few nights a week for the first 90 nights. Movie night, lazy Sunday, kids piling in.
- Turn it every 2 weeksHead to foot, for the first 90 days. Then every 3 months.
Optional: a quarter turn. Turn your King 90° for a night or two so you both sleep across the old middle. It hangs over the base a little, so turn it back after. Skip this if your frame has side rails.
What can qualify.

- Body impressions 1.5 inches or deeper
- Sidewall collapse with no weight on the bed

Not covered
- Impressions under 1.5 inches
- The hump in the middle (normal wear)
- Any stains or spills
- Burns, tears or damage

- Changing your mind about the feel
- A missing law tag
Not loving the feel? That is not a warranty claim. Your 100-night comfort exchange gives you one exchange between nights 21 and 100.
Next stepMeasure it↓A broom handle and a ruler.
1.5″ or deeper can qualify- Strip the bedSheets, pads and toppers off. Nobody on the bed.
- Lay a broom handle across the dipRest it on the high points on either side.
- Measure the gapFrom the handle down to the deepest point. 1.5 inches or more can qualify.
Edges too. If a side bows out with no weight on the bed, lay a straight edge along it and measure the gap. Small, even dimples from the quilting are part of the design.

This little tag protects your warranty.
Keep it on
Never cut it offSwipe to see what not to do.
- It is your proof of warranty. It shows which mattress you have.
- It holds the details the maker checks: model, date and serial number.
- No tag, no claim. Without it, the maker cannot process a claim.
Where is it? A white fabric tag sewn into the side of the mattress, at the head of the bed. Under the sheets, out of sight, and easy to forget.

Keep your mattress in warranty.
Three habits that stop most problems before they start.
Spills stay on topUse a protector from day one.
Any stain, even a small spill, can void the warranty. A waterproof protector keeps it clean.
Head to footTurn it head to foot.
Every 2 weeks while it is new (the first 90 days), then every 3 months. Turn it, do not flip it: most mattresses are built one-sided. Two people, about a minute.
Remind me to rotateGive it the right support.
Any of these four works.
A bunkie board on a frame works too.
Not this
Sagging caused by the base is not covered. No amount of turning fixes a dip that comes from underneath.
Warranty questions, answered.
Is the hump in the middle of my bed a defect?
No. When two people share a bed, each side gets pressed down every night and the middle does not, so the middle stays a little higher. It is normal wear and can happen on any King. For the first 90 nights, sleep in the middle a few nights a week and turn it head to foot every 2 weeks.
How often should I rotate my mattress?
Every 2 weeks for the first 90 days, then every 3 months. Turn it head to foot. It takes two people and about a minute.
Should I flip my mattress?
No, unless your mattress is made to be flipped. Most mattresses today are built one-sided. Turn it 180°, head to foot, instead.
How long does a claim take?
From the day you send your claim to the maker’s final answer, allow up to 6 weeks. The maker reviews every claim, so their response time sets the pace. We keep you posted.
Why do you need the name on the original receipt?
The maker checks coverage against the original buyer’s name on the order, so we need it exactly as it appears on the receipt.
I do not have my receipt. Is that okay?
Yes. We can look up your purchase by the name on the order and the rough date. The law tag helps too.
Why do the photos have to be so clear?
Makers turn down a lot of claims because they cannot read the ruler or the law tag. Use daylight, hold the phone steady and zoom in close.
What happens if my claim is approved?
A replacement is arranged based on the maker’s decision. We contact you by email or phone to plan the next steps.
What bed frame do I need?
A solid platform, bunkie board or matching foundation with centre support. Slats should be no more than 2 inches apart. Broken slats or no foundation can cause sagging that is not covered.
I do not like the feel. Is that a warranty claim?
No. The warranty covers how the mattress was built. For the feel, you have our 100-night comfort exchange, with one exchange between nights 21 and 100.
Does the warranty transfer to a new owner?
No. It covers the original buyer only.
Still not sure? Ask us.
All warranty claims are handled by email.
