Don't Just Take Our Word For It

Real People. Real Sleep Transformations. Real Relief

I Was So tired of Waking Up Exhausted...

— Sarah, one of thousands of sleepers we talked to

We interviewed thousands of people about their sleep struggles:

  • "I tried three different mattress toppers from Amazon and they all flattened in weeks. Total waste of money."— Joyce M.
  • "I tried three different mattress toppers from Amazon and they all flattened in weeks. Total waste of money."— Joyce M.

The Pattern Was Clear, Every Current Solution Is Broken:

  • Your mattress is too firm and causes shoulder, hip, and back pain—but replacing it costs $1,500+ and you're not ready for that.
  • Cheap toppers promise relief but flatten within months, sleep hot, and smell like chemicals—leaving you thinking all toppers are garbage.
  • Memory foam mattresses trap heat and make you wake up sweating at 2am—no matter how many times you flip the pillow or kick off the covers.
  • "There has to be something better than this right?" — Jade S.
Here's What People told Us They

Here's What People told Us They Really Wanted:

  • Pain-free mornings (not "slightly better" — actually waking up without stiffness)
  • Sleep cool all night (no more 3am sweats or constant pillow-flipping)
  • Actually lasts (not another cheap topper that pancakes in 3 months)
  • Affordable (not $1,500 for a whole new mattress)
  • Works on any bed (firm, soft, old, sagging—doesn't matter)
  • Risk-free to try (because nobody wants to gamble another $100 on disappointment)

So We Built Exactly That:


The Marshmallow Topper isn't based on what foam engineers thought people needed.


It's built on what real sleepers actually told us they wanted.

The Technology Behind Your Sleep Transformation

Designed for people who've tried "cooling gel toppers" that failed

Marshmallow-Core™ Dual-Layer System

Marshmallow-Core™ Dual-Layer System

Cheap toppers are one slab of foam—too soft (you sink in) or too firm (you still ache).

 Ours gives you both: a 2" plush layer that cradles pressure points + a 1" support base that keeps your spine aligned.

What Does it Mean For You: Cloud-soft comfort without the quicksand feeling. Won't flatten like those $40 Amazon toppers.

Gel-Infused

Gel-Infused

Most "cooling gel" stops working after an hour because it's still dense foam underneath. 

We use two mechanisms:
Gel-infused open-cell foam (disperses heat 3x faster) + breathable bamboo cover (wicks moisture all night). 

What does It Means For You: No more 3am sweats. No more flipping your pillow to the cool side.

Won't-Flatten™ High-Density Construction

Won't-Flatten™ High-Density Construction

If your last topper went flat in weeks, it's because most use cheap 2.5 lb foam.

 Ours uses 4 lb density foam—60% denser—so it bounces back night after night. Backed by a 5-year warranty.

What does It Mean For You: The last topper you'll need to buy.

How Actually Easy It Is

From box to best sleep—here's how you transform your bed tonight.

Unroll Your Marshmallow Topper

Unroll Your Marshmallow Topper

Take it out of the box, unroll it on your mattress, and let it expand for 2-3 hours (or overnight if you're patient). No complicated setup. No tools. Just unroll and wait.

Let it expand for 4 - 8hrs

Let it expand for 4 - 8hrs

Give it a little time to fully bloom As the Marshmallow Topper unfolds, the high-density foam gently expands to its full plush shape. Let it breathe for 4–8 hours in a well-ventilated room so it can reach its perfect softness and cool feel, ready to transform your sleep.

Sleep. Wake Up Pain-Free.

Sleep. Wake Up Pain-Free.

That's it. Add your sheets, climb in, and feel the difference immediately. By tomorrow morning, you'll wonder why you waited so long.

I've tried literally everything—foam toppers, cooling pads, new pillows, you name it. Nothing helped my hip pain or the fact that I'd wake up sweating at 3am. This topper is the first thing that actually works.

What Makes Marshmallow Unique +

Most toppers are either cooling OR comfortable. Not both. Foam toppers trap heat. Cooling toppers feel like sleeping on a gym mat. We figured out how to make something that's actually soft and keeps you cool. Novel concept.

We use pressure-relief technology, not just "memory foam." Generic memory foam just sinks. Ours adapts to your body, supports your pressure points (hips, shoulders, lower back), and doesn't leave you feeling stuck.

It doesn't smell like a chemical factory. You know that awful off-gassing smell most foam products have? We use CertiPUR-US certified materials, so you can actually sleep on it the first night without fumigating your bedroom.

The cover is removable and washable. Because life happens. Spills, sweat, pets, kids—just unzip it and throw it in the wash.

It stays in place. Elastic straps on each corner keep it from sliding around like every other topper you've tried. You shouldn't have to remake your bed every morning.

Who It Was Built For +

This is for you if:

You wake up multiple times a night and can't figure out why.

Your back, hips, or shoulders hurt every single morning.

You're tired of flipping your pillow to find the cool side at 3am.

You can't afford a $2,000 mattress but you're desperate for better sleep.

You've tried everything—new pillows, sleep apps, melatonin, meditation—and nothing's worked.

You're skeptical of "miracle products" but you're willing to try one more thing because you're exhausted.

This might not be for you if:

Your mattress is completely dead (like, 15 years old and caving in the middle). You need a new mattress, friend.

You love your current sleep setup and have no complaints. Congrats, seriously.

You're looking for something rock-hard. This adds plush comfort and pressure relief.

You need it to fix snoring, sleep apnea, or your partner stealing the covers. It's good, but it's not that good.

FAQ +

Will this actually help my back/hip pain, or is that just marketing? Real talk: if your mattress is completely shot, no topper will fix that. But if your mattress is just too firm or has lost its support, this adds the pressure relief your joints are begging for. Most of our customers with chronic pain notice a difference within the first week.

 I sleep HOT. Like, change-the-sheets-at-2am hot. Will I still overheat? Our cooling technology isn't the gimmicky "cool to touch for 5 minutes" stuff. It actually regulates temperature all night. You might still get warm if you're going through menopause or it's 90 degrees with no AC, but you won't wake up drenched.

 How thick is it? Will my sheets still fit? It's 3 inches thick—enough to make a real difference, but your fitted sheets will still work. Deep pocket sheets fit even better.

 Do I need a mattress protector under it or over it? Over it. Protect your investment, especially if you have kids, pets, or are a coffee-in-bed person (no judgment).

 How long until it expands fully? Give it 24-48 hours to fully expand after unboxing. You can sleep on it right away, but it gets even better after a day or two.

 What if I'm a side sleeper? Stomach sleeper? Side sleepers love it because it cushions hips and shoulders. Stomach sleepers who need something softer than a board also do well. Back sleepers? You're golden either way.

Why You’ll Love It +

You'll actually sleep through the night. Not just fall asleep—stay asleep. No more 3am wake-ups where you're flipping your pillow for the cool side and wondering why you even exist.

Your body won't hurt in the morning. Imagine waking up without that stiff lower back. Without hobbling to the bathroom like you're 80. Without needing 10 minutes to "warm up" before you can function.

You won't wake up sweating. No more kicking off the covers at 2am, then freezing at 4am, then sweating again at 5:30. Your body temperature will actually regulate like a normal human's.

You don't have to buy a whole new mattress. Because who has $2,000 lying around? This gives you 80% of the benefit for a fraction of the cost.

It's yours to keep or return. 30 nights. If you're not sleeping better, you get your money back. Zero risk.

Questions? We Got You

Every topper says 'cooling'... how is this one different? +

Most "cooling" toppers feel cold for about 5 minutes, then you're right back to sweating. Ours uses actual temperature-regulating technology that works all night long—not just a gimmick. It pulls heat away from your body instead of trapping it like regular memory foam. If you're someone who wakes up drenched at 2am, this is the difference between finally sleeping through the night and buying your third "cooling" product that doesn't work.

Will it actually help my back pain? +

If your mattress is too firm or has lost its support over the years, yes. This topper adds pressure relief exactly where you need it—lower back, hips, shoulders. It's not going to fix a completely dead mattress (if yours is 15+ years old and caving in, you need a new mattress, friend). But if you're waking up stiff and sore every morning from a mattress that's just not cutting it anymore, most people notice a difference within the first week.

I'm a hot sleeper AND a side sleeper. Will this work for me? +

Yes. This is literally designed for you. The cooling technology handles the night sweats, and the pressure relief cushions your hips and shoulders so you're not waking up in pain. Side sleepers need something that won't let their joints scream all night, and hot sleepers need something that won't trap heat. You get both.

How thick is it? Will my sheets still fit? +

It's 3 inches thick. Your regular fitted sheets will still work, but deep pocket sheets fit even better. You'll actually notice the difference when you lie down (unlike those wimpy 1-inch toppers that do absolutely nothing), but it's not so thick that you need to buy all new bedding.

Does it have that gross chemical smell? +

Nope. We use CertiPUR-US certified materials, so there's no awful off-gassing smell that makes you feel like you're sleeping in a chemical factory. You can use it the first night without airing out your bedroom for three days.

Will it slide around on my mattress? +

No. It has elastic straps on each corner that actually keep it in place. You shouldn't have to remake your entire bed every morning because your topper migrated to the floor overnight. (We've all been there with the cheap ones.)

How do I clean it? +

The topper itself isn’t machine washable — it can only be spot-cleaned if needed.

Since it doesn’t come with a cover included, most people use regular bed sheets to keep it clean day-to-day.

If you want extra protection, we do offer our BambooShield cover separately. It’s fully removable and machine-washable, so you can just unzip it and toss it in the wash whenever life happens (spills, sweat, pets, kids… all of it) ☁️

How long does it take to fully expand? +

Give it 24-48 hours to fully expand after you unbox it. You can sleep on it right away if you're desperate (no judgment), but it gets even better after a day or two once it's fully expanded.

How long will it last? +

With normal use, 3-5 years. It's not going to fall apart in six months like the cheap ones from Amazon. The materials are high-quality and built to last. When it does eventually wear out, you're still talking about less than a dollar a night for way better sleep.

What if it doesn’t work for me? +

30-night sleep trial. If you're not sleeping better after 30 nights, email us and make it right for you.  You literally have nothing to lose except the back pain and sleepless nights.
