The Nolah Signature 12” is an all-foam mattress with a 12-inch profile. It’s made from different layers of foam that work together to give balanced comfort and support. The top layer uses Nolah’s AirFoam, which is designed to stay cooler and relieve pressure better than standard memory foam.

The mattress feels soft enough to cushion your body but still supports you so you don’t sink in too much. The foam contours to your shoulders and hips, which can help reduce discomfort for people who change positions often during the night. It also stays cooler than many foam mattresses, which is helpful if you tend to sleep warm.

Its construction feels well thought out. The layers are built to last without making the mattress too heavy or hard to move. You still get steady support from edge to edge. For many sleepers, it could work well for both everyday use and long-term comfort.

If you own the Nolah Signature 12”, there are certain things you should know to keep your warranty valid. Following these guidelines can help you take care of your mattress and make it last for years.

Key Takeaways

  • The Nolah Signature 12″ provides soft comfort coupled with firm support, so it’s perfect for combo sleepers who move around.
  • Nolah’s AirFoam is cooler than standard memory foam, which allows hot sleepers to have a better night’s sleep without breaking out into a sweat.
  • The Limited Lifetime Warranty only covers the original purchaser and a proper foundation with less than 5.5″ between slats.
  • Taking off the cover or substituting a subpar foundation can invalidate your warranty, so leave that cover on and utilize good support!
  • Turn the mattress over every few months to maintain even wear and comfort, no flipping required due to its one-sided construction.

How to Avoid Voiding a Nolah Signature 12’s Warranty

Understanding the Nolah Signature 12” Warranty

The Nolah Signature 12” mattress comes with a Limited Lifetime Warranty to show how Nolah values complaints and real user experiences, and safety concerns are clearly addressed through transparent policies and verified customer feedback.

For the first 10 years, you get full replacement coverage, which feels reassuring. After that, the warranty becomes prorated, which still helps if something goes wrong later on. This warranty is only valid for the original purchaser, so it’s not something you can pass on. If you’re thinking of giving it away or selling it later, just know the warranty won’t carry over. That part feels a bit limiting, especially for those who move often or upgrade regularly.

For the warranty to stay valid, the mattress has to be used with a solid foundation. That detail sometimes gets overlooked, but it really matters. Using it on a saggy base or the floor could cancel the warranty altogether.

The brand seems serious about durability, but they also expect the customer to follow the rules. Anyone interested should read the fine print to avoid surprises. It’s always better to know what you’re agreeing to before problems show up.

Who This Limited Lifetime Warranty Covers

This warranty only covers the first person who bought the mattress directly from Nolah or an approved retailer. If you’re not the original buyer, the warranty won’t apply to you. Keeping your receipt is important, as Nolah asks for it to honor the warranty. It’s not one of those policies you can pass down or transfer to someone else. Even if the mattress gets gifted or resold, Nolah still won’t honor the warranty. That’s something worth knowing before you assume coverage continues.

This warranty sticks with the original owner for as long as they own the mattress. Once they give it away or sell it, the protection ends right there. You basically lose the benefit the moment the mattress changes hands. It’s valid in the U.S. and Canada, but not in U.S. territories. So if you live in Puerto Rico or Guam, this might not work for you. They’ve made that pretty clear in the policy details.

What This Limited Lifetime Warranty Covers

The warranty applies if the mattress develops a visible indentation deeper than 1.5 inches, as long as it’s been on a proper support system. A frame with wide slats or poor reinforcement doesn’t count. The mattress needs consistent and solid support to stay in shape. It also covers cracks or splits in the foam or springs that happen under normal use. This means the damage wasn’t caused by jumping on the bed or dragging it around. Just regular sleeping and rotating shouldn’t lead to structural failure.

Manufacturing flaws in the mattress cover are part of the warranty, too. If the stitching starts to come undone or parts of the cover are poorly assembled, that’s not something owners should just accept. It’s a defect, not wear and tear.

Still, the warranty only holds if the mattress is properly supported from day one. Many overlook the frame setup, assuming any base will work. But if the slats are too far apart, or the frame can’t handle the weight, coverage is void.

What This Limited Lifetime Warranty Does Not Cover

Foam softens with regular use, and that’s completely normal. It still supports the body even if it feels a bit different over time. A slight change in feel doesn’t mean the mattress stopped doing its job. Comfort issues past the 120-night trial fall outside of warranty protection. The brand gives that window to decide if it feels right long-term. After that, they expect owners to stick with their choice unless there’s a defect.

Any physical damage such as spills, burns, rips voids the warranty, no matter how it happened. It doesn’t cover accidents or wear caused by pets, kids, or moving. Taking care of the mattress is important in keeping coverage intact.

Mattresses bought secondhand or from random resellers don’t qualify for warranty help. Only purchases from authorized shops count, and only the original buyer gets coverage. If just one part of a mattress set has issues, they only replace that specific piece.

Mattress Cover

If you take the cover off your mattress, you might lose your warranty. For many brands, removing it automatically cancels the Limited Lifetime Warranty. Most people don’t realize this until it’s too late.

The cover isn’t just for looks. It protects the inside of the mattress from damage, dirt, and moisture.
Once it’s gone, the mattress is more likely to get damaged, and the company sees that as breaking the warranty terms. You might think opening it up to clean or check inside is harmless. But doing that can cost you your warranty and possibly money if you need repairs later. Keeping the cover on is the safest way to keep your warranty valid.

A lot of people only find out about this rule after they’ve already removed the cover. Knowing it now can save you from stress and extra costs in the future. Read your warranty details, follow the rules, and your mattress will stay protected.

Buyer Responsibilities

Purchasers have a clear role if they want to benefit from the Limited Lifetime Warranty. They need to send the mattress or mattress cover back to Nolah along with proof of the original purchase date. The return must go to the specific address listed in the warranty terms.

Once Nolah gets the claim, they check if it meets the warranty conditions. If it does, they will either repair the mattress or send a replacement, depending on what works best. The repaired or replaced mattress is then shipped back to the original purchaser. Nolah tries to handle these warranty claims as quickly as possible however, some cases may take longer due to their complexity. Patience may be needed during this process.

Overall, the warranty process depends on the purchaser carefully following these steps. Providing proof of purchase and returning the mattress correctly are essential for making a valid claim and getting support from Nolah.

Using an Improper Foundation

Using the wrong foundation for the Nolah Signature 12″ mattress can lead to issues. Foundations, box springs, or frames with slats that are spaced more than 5.5 inches apart don’t give the support a mattress requires. This type of setup can result in early wear and could damage the mattress over time.

Mattress warranties typically have strict guidelines regarding acceptable bases. If the foundation doesn’t meet these spacing requirements, the warranty could be voided. This means that any problems caused by inadequate support won’t be covered, which can be really frustrating for the owner.

Proper support is essential because it helps keep the mattress’s shape and comfort intact. Without it, the mattress might sag or form lumps, which can negatively impact sleep quality. It’s important to double-check the base before setting up the mattress to prevent these issues. Even if the mattress seems fine initially, an unsuitable foundation can lead to hidden damage. Over time, the mattress may lose its durability and comfort, reducing its lifespan.

Sticking to the recommended guidelines safeguards your investment and ensures the mattress performs as it should.

Maintaining the Mattress Properly

Maintaining a mattress properly can extend its lifespan and keep it comfortable for years. Rotating it regularly helps prevent uneven wear, which often leads to sagging and lumps. This ensures consistent support across the entire surface.

Using a mattress protector is important for maintenance. It protects against stains, spills, and dust mites that can damage materials over time. Keeping the mattress clean preserves its feel and promotes better hygiene.

Finally, a sturdy and supportive bed frame is essential. A weak foundation can cause the mattress to sag prematurely, no matter how well it is cared for. Ensuring the slats or base stay in good condition affects the mattress’s overall durability.

Rotating And Flipping

The Nolah Signature 12” mattress feels supportive from edge to edge. There is no flipping needed since it is designed to be slept on one side only, just as the setup instructions explain. This simplifies your routine and keeps things straightforward.

Rotating the mattress 180 degrees every few months is a good habit. This helps distribute wear evenly across the entire surface so no spot becomes overly compressed. It remains a simple step that maintains comfort over time. This rotation practice does not involve flipping the mattress but ensures you get the most out of the side you do sleep on. It keeps the feel consistent and prevents early sagging. Over time, it contributes to the mattress lasting longer without losing support.

Overall, following this rotation schedule helps preserve the mattress’s quality. It provides a low-effort way to keep things feeling fresh and comfortable for years. Taking care of your mattress in this way results in better sleep nights ahead.
