This Lunarflex 10” firm hybrid mattress is CertiPUR‑US® and OEKO‑TEX® certified, non‑toxic and eco‑friendly. It has 7 premium layers with high‑resilience foam and independent pocket coils, offering targeted spinal support, great motion isolation and no partner disturbance.

Reinforced edges resist sagging, breathable cooling fabric boosts airflow for all‑night comfort. It ships compressed in a box for easy setup, backed by 10‑year warranty and 90‑night sleep trial.

Lunarflex adhere to the most stringent global certification standards, so you can rest easy knowing your sleep space is safe, non-toxic, and free of fiberglass. Our mattresses feature OEKO-TEX® certified fabrics, guaranteeing textiles that are free from harmful substances, while all foam components are CertiPUR-US certified—ensuring low emissions, durable performance, and no ozone depleters, PBDEs, or other harmful chemicals. Together, these certifications deliver a healthier, more sustainable sleep environment for complete peace of mind.

No assembly is required for your Lunarfl—setup is quick, tool-free, and hassle-free! Here’s how it works:
1. **Unbox easily**: Your mattress arrives compressed, rolled, and sealed in a compact box. Simply cut the outer plastic packaging (we recommend using scissors to avoid damaging the mattress cover) and remove the rolled mattress.
2. **Unroll & expand**: Lay the mattress flat on your bed frame (platform, box spring, or adjustable base) and let it fully unroll. No tools, no extra parts—just unroll and go.
3. **Wait for rebound**: The mattress will start expanding immediately, and it typically reaches its full shape and firmness within 24-72 hours (allowing 48 hours is ideal). You can sleep on it right away, but waiting ensures the foam and coils settle to their optimal comfort level.

Pro tip: For faster expansion, keep the room well-ventilated and avoid placing heavy objects on the mattress while it’s expanding!

Not too Fancy pretty Simple but strong queen Bed, it doesn't really look Grey more like cream or white I don't know but the base is pretty solid so it is a Good Bed for the Price and not hard to put together at all.

Very satisfied with this medium firm mattress! Delivered folded in a compacted form. Heavy box. Once opened the mattress expanded very quickly. Very comfortable, but found it to be extremely comfortable when I added a mattress topper.

Very pleased with this mattress! It arrives super fast and was easy to unpack. The tool inside made on wrapping the mattress easy and it returned to normal size in less than 24 hours. It is listed as firm, but still has some cushion to it. I do recommend!

Great mattress overall, but I expected a bit more firmness. I ordered 'medium-firm,' but it leans toward soft. If you're over 200 lbs, you might sink a little. Still, the edge support is excellent, and it's cool to sleep on. Just adjust your expectations.

I bought this for my daughter's college dorm. She said it was way better than the cheap twin beds they gave her. It's firm enough for study sessions, soft enough for late-night Netflix. Even her roommate loves it. For 490, it's a steal.

I sleep hot, so I avoid all-foam mattresses. This hybrid is the best of both worlds: foam comfort on top, airflow below. Woke up dry and refreshed every morning. The knitted cover is soft against bare skin'no itching or static.

The knitted cover is softer than I expected almost like a light blanket on top. Combined with the airflow design, it creates this airy, cloud-like feel that's still supportive. Best sleep I've had in years.

Love that it's CertiPUR-US certified. I did my research no ozone depleters, no heavy metals. Just clean materials that sleep well. Peace of mind matters when you spend 8 hours a night on something.

It's not bad, but I expected more. The comfort foam is okay, but the pocket springs don't offer much bounce. I sleep on my side, and my shoulder sinks into the foam. Also, the bottom fabric is flimsy it already has a small tear. Disappointed.

We got this for our guest room, and now we want to sleep in there! Medium-firm is just right not rock-hard, not sinkhole-soft. It supports my back without killing my hips. Guests keep asking where we bought it.

My old mattress had no edge support couldn't even sit on the side. This one? Strong as heck. I have a dog who likes to jump on the bed, and he doesn't make me bounce. Also, the durable bottom fabric looks clean even after 3 months. Great value for 430.

The mattress is comfortable and supports my back well. The layered structure is clearly designed for durability. However, the initial off-gassing was noticeable had to air it out for 2 days. After that, zero odor. Worth it, but not for those sensitive to smells.

It's a good mattress, but the packaging could be better. The box was dented in shipping, but the mattress itself was fine. Setup was easy, and it's held up well. Just wish there was a bit more firmness in the middle. Still, I'd recommend it.

As someone who sleeps hot, I was worried about foam trapping heat. But this one breathes well thanks to the open-cell foam and ventilation design. I've never been more comfortable. The layered structure really works: soft on top, supportive underneath. Not a single complaint.

As a landlord, I've gone through cheap mattresses like tissues. This one? Still looks and feels new after 8 months of tenant turnover. No indentations, no weird smells. The fiberglass-free fire barrier also gives me peace of mind safety first!

I manage three Airbnb units all now use this mattress. Guests consistently say best sleep ever, and I haven't had to replace a single one in over a year. Durable, clean, and comfortable. A rental host's dream.

Sagging after 3 months. I'm 230 lbs, and I already notice a dip in the middle. The comfort foam layer seems to compress fast. The edge support is weak too can't sit on the side without sinking. Not worth 469.

Just furnished my Airbnb with two of these, and guests keep mentioning how comfortable the beds are in their reviews! After 6 months of constant use, zero sagging. The high-carbon steel coils really hold up. And setup was a breeze just unbox and wait 20 minutes.

This mattress saved our marriage okay, maybe not, but it definitely saved our sleep! My partner tosses like a fish out of water, and I used to count ceiling tiles at 2 AM. Now? Deep sleep, every night. Thank you, pocket coils!

Finally found a mattress that balances comfort and support! The comfort foam layer cradles my shoulders and hips, while the pocket springs keep my spine aligned. My back pain is gone. Bonus: it ships compressed, so no delivery fee. Easy setup.

Perfect middle ground for couples. Not too firm (like sleeping on plywood), not too soft (like quicksand). Just right Goldilocks would approve. And it stays cool all night. Win-win.

I was skeptical about a 400 mattress, but wow this is legit. I'm 6'1 and 200 lbs, side sleeper with lower back pain. The edge support is solid I can sit on the edge without sinking. And the pocket springs? No motion transfer at all. My wife's night shift starts at 3 AM, and I don't wake up when she gets up. Worth every penny.

Perfect for couples with different sleep styles. I need firm support; my wife likes a little cushion. This hits the sweet spot. And the breathable design means no more fighting over the thermostat at night!

Setup took 10 minutes. Unboxed, laid it flat, and it puffed up fast. No weird plastic smell just clean, fresh foam. Slept on it that night, and my chronic lower back pain was noticeably better by morning.

Love the build quality the pocket springs are quiet and stable. The comfort foam layers are very responsive. Only downside: it took 48 hours to fully expand. Also, the top layer felt a bit sticky at first, but it dried out. Otherwise, super comfy.

I'm a side sleeper, my wife's a stomach sleeper we could never agree on a mattress. This medium-firm feel somehow makes us both happy. No more your side is too soft! arguments. Plus, it's breathable I don't wake up sweaty like I did with our all-foam one.

I was nervous about buying a mattress in a box, but this expanded perfectly within an hour. No off-gassing smell at all. And the CertiPUR-US foam feels clean and fresh important since I have allergies.

I was excited to finally get some relief from my old saggy bed, but the delivery was a total disaster. The box was torn open on one side, and the mattress inside was ripped along the edge fabric like someone dragged it across concrete. There was even dirt on the fire-resistant layer!

This mattress has changed my life. I used to wake up every 2 hours from hip pain. Now I sleep through the night. The comfort foam layers are so plush they contour perfectly. And the fire-resistant layer? That's peace of mind for a parent with kids. Definitely recommend if you want support AND comfort.

FAQS

We offer a 200-night risk-free sleep trial for all our mattresses—because we believe you need time to truly adjust to a new sleep surface! Here’s how it works:

Start your trial from the day your mattress is delivered (we ask for a 30-night break-in period first, as new mattresses need time to fully expand and soften to their optimal feel).
If you’re not completely satisfied after 30 nights, contact our support team anytime before the 200th night to initiate a return.
We’ll arrange free pickup of the mattress and issue a full refund (no restocking fees!) to your original payment method within 5-7 business days.

Our mattresses are backed by a 10-year limited warranty to protect you against manufacturing defects—we stand behind the quality of our materials and craftsmanship! The warranty covers:

Structural defects: Sagging greater than 1 inch (excluding normal wear and tear), broken or loose coils (for innerspring models), or defective foam that cracks/breaks down prematurely.
Material defects: Defects in the cover fabric (e.g., unraveling seams) or internal padding that shifts unevenly.

Important notes: The warranty is non-transferable and applies only to the original purchaser. It does not cover damage from improper use (e.g., spills, stains, using an unsupported bed frame) or normal wear and tear over time.

Yes! We make mattress shopping as easy as possible with free curbside shipping to all 50 U.S. states (including Alaska and Hawaii—additional delivery time may apply). For most orders, you’ll receive your mattress in 2-7 business days via FedEx or UPS, compressed and rolled in a compact box for easy setup.

We do not provide old mattress removal or pickup services. For responsible disposal in the U.S., consider these options:

Schedule bulk trash pickup with your local sanitation department.
Donate gently used mattresses to a local charity (e.g., Habitat for Humanity ReStore).
Use a licensed mattress recycling service (e.g., LoadUp) for convenient pickup.

Reach out to our team if you need help finding local disposal resources!

Proper care can keep your mattress comfortable and supportive for years! Follow these simple tips:

Rotate regularly: Rotate your mattress 180° every 3 months (for single-sided models) to prevent uneven sagging—no flipping needed (our mattresses are designed to be used on one side only).
Use a mattress protector: A waterproof, breathable protector will shield against spills, stains, and dust mites (this also helps keep your warranty valid!).
Keep it clean: Spot clean with a mild detergent and damp cloth—never use harsh chemicals or steam cleaners, as they can damage the foam/coils.
Support properly: Always use a firm, flat foundation (box spring, platform bed, or slatted frame with slats no more than 3 inches apart) to avoid structural damage.

Our mattresses are designed to work with most standard bed frames—but the right foundation will maximize comfort and durability! Here’s a quick guide:

Box spring: Works great for innerspring mattresses (adds extra support and absorbs shock) but is not required for memory foam or hybrid models.
Platform bed: Perfect for all mattress types! A solid platform or slatted frame (slats ≤3 inches apart) provides the firm, even support our mattresses need—no box spring necessary.
Adjustable base: Fully compatible! Our mattresses are flexible enough to bend with adjustable frames (great for reading, watching TV, or relieving back pain).

Pro tip: Avoid using soft or sagging foundations (e.g., old box springs with broken coils) — they can void your warranty and reduce the lifespan of your mattress!
