Luonto Seth Sleeper Sofa with Level Function

$4,299.00

The Seth Sleeper takes the classic rolled arm and softens it into something modern and inviting, without losing the warmth that makes a rolled arm feel like home. The gently curved, padded arms are genuinely comfortable to lean against, with the comfort cues of traditional upholstery in a shape that still fits contemporary spaces. The medium-firm mattress is supportive and truly comfortable to sleep on. No bar in your back, and it won't sag over time.

White Glove Delivery

We ship white glove with a scheduled appointment throughout the continental United States.

Quick Ship fabrics arrive in about 3 to 4 weeks. Custom fabrics and leather are made in Europe and take about 3 to 4 months.

White Glove delivery is $200, the minimum required by Luonto and the same rate you'll find on every other retailer's website. As your delivery date approaches, your appointment narrows to a 4-hour window so you're not waiting around all day. We bring your furniture inside, move it into the room of your choice including up to two flights of stairs, set it up, and remove all packaging. Seth, Michael, or Isabella are watching your order the whole way, and we can arrange a Certificate of Insurance for buildings that require one.

We do not deliver to Alaska, Puerto Rico, the U.S. Virgin Islands, Guam, or internationally. Some addresses sit far enough from our carrier's network that we need to quote them individually. Check your zip code below and we will tell you right away.

Every Luonto sleeper uses the same 5-inch cold-cured high resilience foam — not just as a mattress, but as the sofa seat itself. That means what you sit on and what you sleep on are one and the same: a medium-firm surface that is genuinely comfortable and supportive in both positions.

When the sleeper opens, you will never feel the breaks. The foam is cut so cleanly and precisely that the surface stays smooth and seamless from edge to edge — no lumps, no gaps, no metal bar in your back.

These are not guest-only sofas. They are built to be opened and slept on every single night, and the foam holds up. In over ten years of selling Luonto, we have never seen a single case of sagging or indentation. They simply do not break down. If someone in your home prefers a softer, more cloud-like feel, a mattress topper drops right on top and transforms the experience instantly.

Construction breakdown

The Level Function is our most straightforward mechanism. Lift from the center of the frame and you're open. Gas lift assist cylinders make it even easier. Because of how it's engineered, the Level Function has the fewest breaks, giving you the most clean looking sleeping surface. The slight slope of the back even creates a natural "headboard" so guests can sit up comfortably in bed. Available in King, Queen, Full XL, and Cot.

Sustainability is not an afterthought for Luonto. It is built into how every sleeper is designed and manufactured. Each piece is handcrafted in Finland using certified, responsibly sourced wood from renewable Nordic forests, along with water based glues and low emission materials that support healthier indoor air quality.

Their factory operates with renewable energy, and production waste is carefully minimized and recycled whenever possible. Just as important, Luonto builds sleepers to last. With durable construction and replaceable components, these pieces are designed for long term use rather than quick replacement. The result is furniture that is thoughtfully made, environmentally responsible, and built to serve your home for years.

10 Year Structural Coverage – Your frame and spring system are built to last and protected for the long term.

1 Year Component Coverage – Sleeper mattresses, electrical components, motors, controls, and all fabric or leather coverings are protected against manufacturing defects.

Cushions and pillows are warranted against loss of resilience under normal use. Some softening and flattening will occur over time and are considered normal wear rather than defects. Fabric coverings are warranted against seam slippage, fraying, and dye transfer. Leather coverings are warranted against splitting, seam slippage, and dye transfer. Natural characteristics such as nap variation, wrinkling, and grain differences are inherent qualities and not considered defects. Customer’s Own Material and items treated with aftermarket protection are excluded.

How It Works

Seth Level Function Sleeper Sofa

Seth Level Function Sleeper Sofa Seth Level Function Sleeper Sofa Seth Level Function Sleeper Sofa
The Level Function is our top sleeper mechanism, opening in one easy motion by lifting from the front of the frame with assisted open technology that extends conventionally out from the wall. Standard gas springs ensure a soft, controlled close every time with no slamming on the floor.
