Frequently Asked Questions

Quickly find information you really care about.

What kind of back pain relief can I expect?

-

A double-layer foam construction offers a firm sleep surface, rated 7 out of 10, to align the spine and alleviate pressure points, especially beneficial for back and stomach sleepers.

Does the topper help with cooling?

+

The topper uses high-density memory foam infused with bamboo charcoal to absorb moisture, eliminate odors, and help keep the bed fresh throughout the night. However, for a hot sleeper, a cooling collection mattress is the most recommended.

What does bamboo charcoal do in the foam?

+

Bamboo charcoal helps absorb moisture, neutralize odors, and maintain a fresher sleep surface—perfect for long-term cleanliness.

Does it relieve back pain?

+

Yes. High-density memory foam is engineered to conform to your curves, distribute weight evenly, and align your spine to relieve pressure points.

Will the topper fit securely on my mattress without sliding around?

+

The topper includes four elastic corner straps and a non‑slip bottom to keep it in place, even if you move frequently during sleep.

Is the topper safe for people with allergies or chemical sensitivities?

-

Our CertiPUR-US-certified memory foam is free of harmful chemicals, including formaldehyde and heavy metals, ensuring a safe sleeping environment. Plus, bamboo charcoal is naturally hypoallergenic, offering added peace of mind!

Will there be an initial odor?

+

CertiPUR-US and Oeko-Tex certified memory foam ensure there are peculiar smell and no odor.

Does it contain fiberglass?

+

It is CertiPUR‑US and OEKO‑TEX certified, made without harmful chemicals, and confirmed to be fiberglass-free.

How to unbox the mattress topper?

-

Unbox is simple. Just 4 steps. Here are the instructions:

① Clear your bedroom floor and ensure a clean, flat surface near your bed for unboxing.

② Use the small plastic cutter provided to cut open the vacuum-sealed bag and unroll it.

③ Let the topper expand on the bed. Please note, do not sleep on it or cover it with sheets yet. Allow the topper to expand for 48-72 hours. After it has fully expanded, pull the non-slip elastic straps around the corners of your mattress to secure it in place.

④ Cover a bed sheet and enjoy it.

How long does it take to fully expand?

+

The topper comes in a vacuum‑compressed box. Please wait 24‑48 hours for full expansion after unboxing. For best results, keep the room temperature at least 75°F during this process.

What to do if the topper doesn't fully bounce?

+

For lumpy foam, please use a hairdryer on flat areas. The heat helps it bounce back faster.

Is this topper too firm for side sleepers?

-

Firm to extra firm makes it ideal for back and stomach sleepers. Side sleepers who prefer extra support may also enjoy it, but those seeking plush softness might prefer a medium-firm or soft topper.

What is the firmness level of this topper?

+

Designed to be firm to extra-firm. With a reversible firmness, you can flip the topper to find your preference.

Firm vs extra firm, what's the difference?

+
  • On the top side: Firm feel for a balance of support and comfort.

  • On the bottom side: Extra-Firm sensation for maximum support, often preferred by those with back pain or who sleep on their back/stomach.

Can I wash the topper, and how should I care for it?

-

Removable, zippered cover that is machine washable. The foam itself is not washable; spot cleaning is recommended if needed.

Is the Bamboo Charcoal mattress topper washable?

+

Of course. Durable zipper design for a quick, removable cover, allowing machine washing and keeping the sleep surface clean. But keep in mind that the inner foam topper can't be cleaned.

What payment methods do you accept?

-

We accept Visa, Mastercard, American Express, Discover, PayPal, Amazon Pay, and financing via Affirm. All payments are securely processed via Shopify Payments.

Do you offer financing?

+

After using this for a couple of months it has functioned exactly as described in the advertisement, given quality use, is as firm as described. I was shopping for an actual firm to extra-firm topper and this is it. Our person using this nightly now reports this supports without sinking down into it, no more sore shoulders or numbing arms after a night's sleep, (side sleeper) and no problem with turning over and no uncomfortable experience of sinking downwards into it. This firmly supportive without that falling into a crater sinking that occurs with squishy types of foam. This doesn't "jiggle", collapse in on itself or fall over when stood on the floor on its side, it retains its shape and basically can stand by itself on its edge even though it is not rigid. The person here using it is an adult with a 185lbs. or so weight and this topper is retaining thickness, form and performance like new without rigidity. Side note; if someone needs to push down on their topper with their hands in order to get into a standing position from lying flat, this topper will support and give aid for that motion as opposed to much softer foam toppers, (please check your own situation for safety requirements and need, do not substitute a topper for medically necessary metal equipment, etc.). Also of note, since the person using this is larger in weight, they experience comfort from this topper as well as needed support and a significantly lighter-weight person might find this topper a bit too firm if they would be expecting to have a very soft "sink into a pillow" experience. However, this topper is comfortable! This topper is very well constructed, the value for price did not disappoint and I highly recommend this for a truly firm, supportive topper that has comfort also. There was a slight plastic odor that quickly dissipated once plastic wrapping was removed and it was odor free after the initial instructed waiting period passed. I like the heavy materials used for the covering, and the quality of firmed support this allows for even a heavier/more muscular person. Within our use, this topper is not a heat-producer like is reported with Tempurpedic foam. I definitely recommend this topper.

It is fantastic if you need solid support. It's truly firm and has significantly reduced my back pain, especially helpful for a mattress that was too soft. My sleep quality has improved immensely. The topper expanded quickly, and the cover feels good, although the corner straps could be better designed as they sometimes slip. It's a great value and a much cheaper alternative to a new mattress for firming up your bed. Highly recommend for those seeking a genuinely firm topper for back support and better sleep!

I am not sure this is going to work with my bed. I have an adjustable bed and this topper does not really help anymore than just having my bed without the topper. Nice topper, but just not working like thought it would. I have even tried both sides. I will try longer though. Thank you Sheila

After several weeks of use, the topper still holds its shape well. The foam hasn’t flattened, and the comfort level feels consistent night after night.

Excellent👍Keep that quality up and the price down and you will be sold out all the time.

I received this mattress topper a few days ago, and I can confidently say it’s one of the best investments I’ve made. The firmness is outstanding—just the right balance of support and comfort. Even after only two nights, I’ve noticed a significant difference in my sleep quality, and best of all, no back pain! The materials feel high-quality, and it truly transforms the bed. I couldn’t recommend it more!

T
Tiffany (Singapore)

I recently bought a new bed that turned out to be way too soft, and within a few days I started having neck and back pain. I added this firm mattress topper and within one week I noticed a significant improvement. The support is perfectfirm without being uncomfortable and it immediately made my bed feel more stable.

Another big plus: no weird smell at all, unlike a previous topper I purchased from another company.

Overall, I’m extremely satisfied. If your bed is too soft and causing pain, this topper is definitely worth it!

Abby (Singapore)

When I first unwrapped this and let it expand I was so excited! I loved the way it felt right away, the thickness is great, and the firmness seemed just right for me. Me. I couldn't wait to get it on my bed. After waiting the 48 hours I was able to get it onto my bed, the straps to attach it are great and super helpful, and it fit perfectly. When I tried laying down on it, I couldn't wait to go to bed because it felt so good!

Here's where the problem comes in for me, unfortunately. This mattress pad is way too hot for me. I've been waking up sweating every night, and unable to fall back asleep. It is so comfortable and I wanted to love it so bad, but It just isn't for me. I am a hot sleeper, but I thought this had cooling foam that might make it work for me. It is a great product, but just not for me.
I will say that I am super bummed or stressed out I guess trying to handle the return process. It is supposed to go in the original box, but now that it has expanded it is way way too big. I don't own a vacuum sealer like the other reviews are saying. I'm trying to figure out what to do before the return window closes, I will edit this and let you guys know if I figure something out! Hope this helps somebody.

After my mattress started sagging and causing me bad back pain, I ordered this mattress topper to avoids ordering a new mattress for the time being! It arrived compressed, was light enough for me to put on and adjust on my bed. It said 48 hours for it to expand, but mine took more like 12. No chemical smell or anything which I have experienced with others. Fits perfectly on my queen bed and is firm but comfortable, which is exactly what I need for a good night’s rest. Feels like great quality, especially for the value it costs. I took my first nap on this thing and immediately needed to right this review because I love it so much. 5/5 highly recommend.

D
Deborah (Singapore)

I ordered a queen size 3 inch topper and the first one sent was only a full size but they sent a replacement in the correct size that arrived very quickly. After allowing it to expand on the bed for 72 hours it only expanded to 3 inches not 4 inches. And it had a smell but that disappeared after the 72 hours. Comfortable but haven’t slept on it long enough to say it will help with back issues.

W
Wesley

This was as described. It was easy to install with the corner straps to affix to your mattress. The firmness of the topper is exactly what I was looking for.

M
Michael

I got this topper because my mattress was way too firm, and it made a huge difference. It added just the right amount of softness without feeling like I’m sinking in.

It did take about a day to fully expand, but once it did, it’s been amazing ever since.

M
Miller (Singapore)

We added this topper to our RV mattress, and it’s been amazing on long trips. It completely changed how the bed feels — soft, cool, and supportive.

It did take about 24 hours to fully expand, but after that, no complaints at all.

B
Brian

Bought this topper to fix a firm mattress, and it worked perfectly. It softened the bed just enough without making it feel saggy.

It took about a day to fully expand, but once it did, it’s been super comfortable. Great quality for the price.

R
Ryan Collins

Bought this for my RV, and I’m shocked at how much more comfortable the bed feels. It’s not too soft, not too hard, just right.

The best part is that it doesn’t slide around, even while driving. Great product for travelers.

O
Olivia Simmons

I work long hours and used to wake up sore from my old bed. This topper made a huge difference — it’s plush but supportive, and my back pain is basically gone.

The foam feels dense and high-end, and I love that the cover can be removed and washed.

R
Rivera

I bought this for my parents, who are in their 60s and needed something softer on their joints. They both love it and said they sleep better now than they have in years.

It’s supportive, cozy, and really well-made. Couldn’t ask for more.

G
Grace Carter

I’m a hot sleeper, so I was worried about overheating. This topper actually stays cool all night. It feels soft yet supportive and doesn’t make me sink too deep.

The only reason I didn’t give five stars is because it took almost two days to fully expand — otherwise, perfect.

B
Benjamin

We added this topper to an older mattress that was getting uncomfortable, and it completely transformed it. It feels like sleeping on a hotel bed now.

It expanded quickly and didn’t have any odor, which I appreciated. My back feels much better too.

L
Lily

The topper is soft and comfortable, just a little thicker than I expected. That’s not a bad thing — it actually makes the bed feel more luxurious.

It stays in place well and really helps reduce pressure points when sleeping on my side.

R
Ryan

This topper completely saved my back. My mattress was too hard, and I used to wake up sore. After adding this, I sleep straight through the night.

It feels high-quality and doesn’t flatten out after sleeping on it for weeks.

J
Jessica Collins

My husband and I have completely different mattress preferences — he likes firm, I like soft. This topper gave us the perfect middle ground. It softened our bed just enough without losing support.

The quality feels premium, and it expanded quickly with no chemical smell. Love it!

B
Brian Torres

I got this for our RV because the factory mattress was like sleeping on a rock. This topper turned it into something genuinely comfortable. It’s thick and plush, and even after hours of driving, it doesn’t slide around.

Honestly, it feels better than our bed at home.

B
Benjamin

I travel a lot for work and stay in plenty of hotels, and this topper honestly makes my bed feel even better than most of them.

It’s firm enough to offer real support but still has that luxurious give when you lie down. I’d recommend it to anyone with an older mattress that just needs a boost.

C
Carter

This topper feels like a cloud, but somehow still keeps you supported. I sleep cooler, and my partner says it even reduced how much he tosses at night.

It also doesn’t slide around, which was a big issue with other toppers we’ve tried. Super impressed with the quality and comfort.
