Indoor comfort, outside
Outdoor comfort shouldn't come with conditions. EcoDry SmartFoam™ is engineered to handle whatever the season throws at it — draining fast after rain, resisting heat and humidity, and holding its shape through months of real use.
Supportive enough for long afternoons, lightweight enough to rearrange whenever the mood strikes. Certified to ANSI/BIFMA X5.4 — commercial-grade durability, proven safe and built to last.
Weatherproof by design
From sun to storms, the M1 Outdoor is built for real outdoor exposure. Solar Weave™ fabric resists UV, spills, and fading — keeping your sofa looking sharp through every season, without the upkeep.
Paired with an outdoor-rated frame designed for heat, rain, and humidity, this is furniture that doesn't ask you to worry about the forecast. OEKO-TEX® certified — made with materials tested safe for people and the planet.
Lightweight modularity
The M1 Outdoor is built to move with you. Each module is light enough to carry, easy to rearrange, and designed to fit any outdoor space — from a compact balcony to a full backyard setup.
No tools. No hassle. Just pick it up, place it, and make it yours.
Easy delivery and set up
The M1 Outdoor arrives compressed in a compact box — light enough to carry on your own, small enough to fit in your car. No movers, no freight deliveries, no waiting around.
Each module connects to the next with hidden YKK zippers — keeping your configuration locked in place on any surface, with no drifting and no gaps. From box to backyard in minutes.
Built to breathe
The included Air Lift Pads raise each module off the surface, creating continuous airflow underneath — so water drains fast and moisture has nowhere to settle. The kind of detail you won't think about, until you realize every other outdoor sofa doesn't have it.
Four pads per module, velcro-attached to the base. No tools, no extra steps — just lift, place, and breathe easy.
Built for all types of weather
Solar Weave™ UV-safe and weatherproof fabric naturally shifts in tone with changing light and weather — from bright mornings to golden afternoons and summer storms.

This outdoor furniture set is so amazing. It’s comfortable and looks like I paid more than I did.
I am OBSESSED with this setting. I get so many compliments on it
We love it, I just wish we could have the cushions with them. Thank you
Love it
Great product durable yet comfy. Looks great too
Great product and fantastic service
Best add on ever. I use it as an extra seat, a footrest, or pull it into the set when we have people over. It’s really easy to carry and doesn’t feel bulky at all. Love how flexible it is!
Delivery was delayed, the colour wasn’t what I expected, and it took a long time to feel comfortable. I wouldn’t buy it again.
I use this as a standalone chair by the pool and it’s been great.
This armless seat is such a win. I grabbed it as an extra piece for when friends come over and it’s perfect for that. Super light to move around! Honestly one of those things you don’t know you need until you have it.
Wasn’t sure if a single seat would be worth it but i’m glad i ordered it. It’s comfortable enough to use alone and tough enough to leave outside without worrying. Zero regrets, this thing is way better than I expected.
Needed one more seat without buying a whole new sofa and this was exactly it. Moves around easily and clicks into the rest of the sofa like it was always there. 10 out of 10 purchase.
The product is great and I’m very happy with the quality. I’m giving one less star only because the delivery arrived 4 days later than expected. Other than that, no complaints.
FAQs
What is the height of the couch?
When fully expanded, the total height is 63cm/24.8″ —measured from the bottom to the top of the backrest— which places the couch in the low-profile category. As for the seat height, the couch measures 38cm/15″ —the distance from the bottom to the seating surface. The classic low-profile design helps create an open and spacious look, making smaller spaces feel more airy and inviting.
What is EcoDry SmartFoam™?
EcoDry SmartFoam™ is our outdoor-engineered foam that stays comfortable through sun, rain, heat, and humidity. It’s breathable, fast-drying, and mold-resistant — wrapped in Solar Weave Fabric™ for UV protection, spill resistance, and long-lasting durability.
How much is shipping?
We ship to you for free. We are passing the savings from our logistics innovation to you.
How does assembly work?
We use a high-grade YKK zipper that connects the modular pieces in seconds. YKK stands for: Yoshida Kōgyō Kabushikigaisha. It is the world's leading zipper brand headquartered in Japan.
How does the 100 day trial work?
Love it or return it within 100 days for a $99 flat fee. Just keep it in original condition, protect it, and we’ll handle the rest, including return labels and a full refund once it's processed.
How do I clean the sofa?
M1's Performance Weave repels liquid. If a spill occurs, quickly soak up the spill with an absorbent towel. If marks remain, dampen a cloth with warm water and gently dab away stains.
How much weight can it support?
It is impossible to break your sofa with weight thanks to Rove Lab SmartFoam technology. It took a 10 ton press to condense your sofa down into its revolutionary packaging.
Does the sofa change form over time?
Everything wears with time, but we’re confident it’ll last for years. Our lifetime warranty ensures you can get a new replacement sofa anytime under the warranty terms.
What is covered by the warranty?
From our Performance Weave fabric to the game-changing Smart Foam, every component of your sofa is protected from wear and tear under our warranty. While the fabric is treated to help you clean up spills, the warranty does not cover spills and stains. Learn more.
Can I leave the M1 Outdoor outside all year?
Yes. EcoDry SmartFoam™ and Solar Weave Fabric™ are built for all-season use, resisting moisture, UV rays, heat, and cold — perfect for any climate.
Does it fade in the sun?
No. Solar Weave Fabric™ is UV-stable and fade-safe, keeping colors vibrant even with long-term sun exposure.
