You found the mattress. You got it home. Now comes the best part: actually sleeping on it.
But a new mattress can also bring a few questions. How long will it take to get used to? What exactly are all those layers doing? Is your partner tossing and turning going to wake you up? And do you really have to flip this thing every few months?
If you’ve recently purchased a Beautyrest Black or Serta iSeries NXG mattress, here’s what to know about the comfort, support and cooling technology now working underneath you.
How long does it take to adjust to a new mattress?
Give your body at least 30 nights to get acquainted with your new mattress.
Even when a mattress felt perfect in the showroom, sleeping on it for eight hours is different from testing it for a few minutes. Your body is getting used to a new combination of support, pressure relief and cushioning, while the mattress’s comfort materials are settling into their everyday feel.
So if night one isn’t immediately the best sleep of your life, don’t panic. Give it some time.
Warners’ Stellian’s 120-night comfort guarantee includes a minimum 30-night adjustment period before a qualifying mattress exchange.
Will my new mattress feel different after a few weeks?
It can, and that’s normal.
Premium comfort materials may become a little more conforming as you spend more time sleeping on them. At the same time, your body is adjusting to a mattress that may support you very differently than the one you just replaced.
Think of it less as the mattress “wearing out” and more as the two of you getting to know each other.
Why did my mattress feel softer in the store?
Because the mattress you tried in the showroom has already had a head start on its break-in period.
Showroom mattresses have had plenty of people sit, lie and test them, so their comfort layers have already had time to soften and conform.
The mattress delivered to your home, on the other hand, is brand new. No one has slept on it, tested it or broken in those comfort layers yet.
That means your new Beautyrest Black or Serta iSeries may initially feel a little firmer than the one you remember from the showroom. As you sleep on it night after night, the comfort layers begin to settle and conform to your body, bringing the feel closer to what you experienced in the store.
So if your first thought is, “Wait, was this the same mattress I tried?” give it some time. A brand-new mattress just hasn’t had nearly as many visitors as the showroom model.
What makes a Serta iSeries NXG mattress supportive?
Several layers work together to contour around the body and relieve pressure quickly.
Serta iSeries combines:
- Carbon Fiber Memory Foam
- NXG Memory Foam
- Micro Coils
- HD Memory Foam
Together, these materials are designed to provide instant pressure relief while maintaining the support underneath you.
That’s especially important around areas like your shoulders and hips, where more pressure tends to build up while you sleep.
How does Beautyrest Black support your body?
Beautyrest Black is built around individualized support from head to toe.
At the center of the support system is Triple-Stranded Pocketed Coil® Technology, designed to respond individually to your body’s movement and weight.
Instead of one large interconnected support system moving together, the pocketed coils can respond more independently. That helps create personalized support across different areas of your body.
It’s basically the mattress version of: you do you.
How does Beautyrest Black provide pressure relief?
Beautyrest Black pairs its coil support system with FORM™ HD material for additional pressure relief and comfort.
The comfort materials help cushion areas that press more deeply into the mattress while the coil system underneath continues providing individualized support.
That combination lets the mattress feel comfortable without losing the supportive feel underneath.
How do Beautyrest Black and Serta iSeries NXG help you sleep cooler?
Temperature management isn’t just about making a mattress feel colder. It’s about helping create a more comfortable, balanced sleep environment throughout the night.
That can matter whether you’re the person kicking off the covers at 2 a.m. or the one pulling them back on.
Serta iSeries NXG
Serta iSeries starts with a CoolFeel™ Cover designed to provide an immediately cool, comfortable feel when you first get into bed.
Underneath the cover, Carbon Fiber Memory Foam helps manage heat while also contributing to pressure relief.
Select models also feature the CoolFeel™ Plus System, adding another layer of temperature-management technology.
For warm sleepers, that can help prevent excess heat from building up around the body. But temperature management can benefit cooler sleepers, too. Rather than constantly trapping heat, these materials are designed to help create a more balanced sleep surface, making it easier for your bedding and room temperature to do the rest.
Beautyrest Black
Beautyrest Black uses its Sleep Climate™ Surface and BlackICE® Max technology for temperature management.
These technologies are designed to help regulate the sleep environment while the mattress’s support and pressure-relieving layers do their jobs underneath.
For someone who sleeps hot, that can mean less unwanted heat buildup. For someone who tends to sleep cold, the goal isn’t to make the bed colder. It’s to help maintain a more consistent, comfortable sleep surface so you’re less likely to experience dramatic temperature swings during the night.
Think of it less as a “cold mattress” and more as a mattress designed to help keep your sleep environment in a comfortable zone.
Will I feel my partner moving on the other side of the bed?
A premium mattress can help reduce how much movement you notice from another sleeper.
Beautyrest Black’s Triple-Stranded Pocketed Coil® Technology provides individualized support, meaning movement on one part of the mattress doesn’t require the entire support system to move with it.
Serta iSeries NXG combines foam comfort layers with its coil and micro-coil systems to provide contouring support while responding to each sleeper.
Will your mattress stop someone from stealing the blankets? Unfortunately, mattress technology has limits.
Do I have to flip my Beautyrest Black or Serta iSeries NXG mattress?
No. These mattresses are designed as one-sided mattresses and don’t need to be flipped.
That means you can forget the old mattress routine of wrestling a queen or king mattress upside down every few months.
One less household chore. We’ll take it.
Do I need to rotate my new mattress?
Routine rotation isn’t required for the Beautyrest Black and Serta iSeries NXG mattresses we’re discussing here.
Always follow the care instructions that come with your specific mattress, but you do not need to build regular mattress flipping or turning into your calendar.
Are body impressions in a new mattress normal?
Yes. Some settling and comfort impressions are a normal part of how your new mattress is designed to work.
Beautyrest Black and Serta iSeries mattresses are designed to conform to your body, so a little settling is normal. You may notice slight impressions where you sleep most or even a small ridge in the middle of a King mattress where no one spends much time.
That doesn’t mean the mattress is losing support. The comfort layers are simply doing their job.
And if that middle ridge starts looking a little too proud of itself, roll toward the center and snuggle once in a while. Problem-solving has never been cozier.
Deep or persistent sagging is different, so if something looks unusual, check the support underneath and your mattress warranty guidelines.
Can I use an adjustable base with my mattress?
Yes. The Beautyrest Black Hybrid XCS and Serta iSeries NXG Hybrid mattresses we sell at Warners’ Stellian are compatible with adjustable bases.
An adjustable base lets you raise or lower different parts of the mattress, giving you more flexibility for sleeping, reading, watching TV or simply finding a position that feels most comfortable.
If you’re considering adding an adjustable base, a Warners’ Stellian mattress specialist can help you choose the right one to pair with your mattress.
Does the foundation under my mattress matter?
Yes. Even a premium mattress needs proper support underneath it.
The right frame, foundation, platform or adjustable base helps your mattress perform the way it was designed to.
For Queen and King mattresses, proper center support is especially important. An unsupported or uneven foundation can affect how the mattress feels and may contribute to sagging over time.
If you’re replacing an old mattress but planning to keep the existing foundation, it’s worth checking that setup before your new mattress arrives.
Do I need a mattress protector?
Yes, and it’s one of the easiest ways to help protect your mattress investment.
It helps guard against everyday spills, stains, sweat and moisture without changing the feel of the mattress underneath.
For Warners’ Stellian’s 120-night comfort guarantee, you’ll need to purchase and use one of the Bedgear mattress protectors we sell with your new mattress. It’s a simple step that helps keep the mattress clean, protected and eligible for the guarantee.
Look for a breathable protector so you’re adding protection without getting in the way of the cooling and comfort features built into your Beautyrest Black or Serta iSeries mattress.
What sheets work best with a premium mattress?
Start by making sure your sheets fit the height and setup of your particular mattress.
Premium mattresses can be taller than the mattress you replaced, especially models with additional comfort layers. Measure the mattress height, including your mattress protector, and check the pocket depth on the fitted sheet before you buy.
If you have a split-head mattress with an adjustable base, you’ll also want sheets made specifically for a split-head setup. These are designed so each side of the head of the bed can move independently while the lower portion of the mattress stays together. A standard fitted sheet won’t give you that same flexibility.
Breathable sheets are also a great match for a Beautyrest Black or Serta iSeries mattress, especially if temperature comfort is important to you. They can work alongside the cooling and temperature-management technologies already built into the mattress instead of trapping extra heat.
No sense investing in a mattress designed to keep you comfortable all night and then wrapping it in sheets that fight against it.
Why does my mattress feel so different from my old one?
Because there’s probably a lot more happening inside it.
If your previous mattress was several years old, moving to a Beautyrest Black or Serta iSeries can mean an entirely different combination of foams, coils, cooling materials, zoned support and pressure-relieving technology.
For example:
| Serta iSeries NXG | Beautyrest Black Hybrid XCS |
| 5-Zone Coil Support System | Head-to-toe individualized support |
| Serta Micro Coils | Triple-Stranded Pocketed Coil® Technology |
| HD Memory Foam | FORM HD material |
| NXG Memory Foam | Pressure-relieving comfort material |
| Carbon Fiber Memory Foam | Sleep Climate™ Surface |
| CoolFeel™ Cover | BlackICE® Max |
| CoolFeel™ Plus System | Advanced temperature management |
Your body may simply need some time to adjust to having support and cushioning in different places than it did on your previous mattress.
What if I’m still not comfortable after 30 nights?
If you’ve given the mattress a fair adjustment period and something still feels off, it’s worth looking at your entire sleep setup.
Before deciding the mattress isn’t right, consider:
- Is the mattress properly supported?
- Is your pillow right for your sleeping position?
- Is your foundation in good condition?
- Would an adjustable base make you more comfortable?
- Is the firmness level right for how you normally sleep?
If you’ve worked through those questions and the mattress still isn’t right for you, Warners’ Stellian offers a 120-night comfort guarantee on qualifying mattress purchases, with a one-time exchange available after the required adjustment period and subject to the terms of the policy.
Your Mattress Is Doing More Than You Think
When you’re asleep, you probably aren’t thinking about micro coils, carbon fiber memory foam or triple-stranded pocketed coils.
And that’s kind of the point.
Your Serta iSeries or Beautyrest Black mattress is designed to combine support, pressure relief and temperature management behind the scenes so you can focus on the part that actually matters: getting comfortable and getting some sleep.
