The Simon Li Liviana Sleeper Sofa solves a common problem neatly: it gives you a comfortable living-room sofa and a queen guest bed without the bulk of a sleeper sectional. Its Linkrest mechanism is quick to operate, and the seat cushions fold away with the bed instead of cluttering the floor. The 4.75-inch mattress is best for occasional guests, however, and the polyester upholstery holds more warmth than a breathable performance fabric.
The Liviana at a glance
| Sofa | Overall Score | Pros | Cons | Best For |
| Simon Li Liviana | 4.0/5.0 | Queen bed; tidy Linkrest conversion; cushions store with the mechanism | Thin mattress for frequent sleep; fabric can feel warm | Occasional guests, movie nights, and multipurpose living rooms |
Is the Liviana worth buying?
Yes—if you need a sofa most days and a guest bed only when friends or family stay over. The Liviana sits more like a supportive everyday couch than a temporary sleeper, yet it opens without requiring you to stack loose cushions elsewhere. Its 4.75-inch foam mattress is adequate for a weekend but not substantial enough to replace a regular bed. At $1,999.99, the value comes from the clean conversion, queen-size sleep surface, included setup, and Costco purchase experience rather than from a luxurious mattress.
Who it suits:
- Households that host overnight guests a few times a year
- Couples who want a conventional sofa instead of a bulky sectional
- Shoppers who value an easy, uncluttered conversion
Who should skip it:
- Anyone planning to sleep on it every night
- Hot sleepers who already find foam and polyester too warm
- People who want an especially deep, soft lounging seat
What we checked
We used the Liviana for upright sitting, laptop work, relaxed movie nights, and two nights of guest sleep. Our sofa testing process also included repeated opening and closing, front-edge support, surface warmth during a one-hour sit, light-debris cleanup, and measurements in seating and bed modes. The final five-point score combines assembly, cooling, comfort, durability, layout practicality, cleaning, and value.
Our testing experience
The Liviana felt settled and supportive from the first long sit. The back cushions held us upright enough for laptop work, while the seat still had enough give for a movie. Under a 180-pound tester, the center of the seat compressed 1.7 inches and the front edge compressed 1.3 inches. That modest difference explains why standing up felt secure instead of as though the cushion were folding over the rail.
Our measurements came in at 81.1 inches wide, 37.6 inches deep, and 34 inches high—within two-tenths of an inch of Costco’s listed dimensions. One person averaged 26 seconds to open the bed and 31 seconds to close it across 10 cycles. The Linkrest motion stayed smooth, and the cushions disappearing beneath the mechanism made the process much tidier than a conventional pull-out with loose cushions on the floor.
Cooling was the weaker part of the sitting experience. After a 60-minute sit in a 72°F room, the occupied fabric surface rose by 4.8°F and still felt slightly warm 10 minutes after we stood up. That result fits the 3.6/5 cooling score: acceptable in an air-conditioned room, but not ideal for someone who runs hot.
Two adults used the bed for two nights. The first-night comfort rating averaged 3.8/5, then slipped to 3.4/5 on the second night as the 4.75-inch mattress made shoulder and hip placement more noticeable. The queen width was useful, and there was no pronounced bar across the center, but both sleepers preferred it as a short-stay bed. Those results support the Liviana’s 4.1/5 overall comfort score: good seating paired with merely adequate overnight comfort.
What we liked:
- The bed opens quickly, and the cushions store out of the way.
- The front edge stays supportive during frequent sitting and standing.
- Daily seating feels balanced: structured enough for work, comfortable enough for a movie.
Who it is best for:
- Hosts who need a dependable bed for weekend guests
- Living rooms that cannot accommodate a full sleeper sectional
- Shoppers who prefer a familiar transitional design over a low, modern profile
Where it falls short:
- The mattress is too thin for frequent or long-term sleeping.
- The polyester cover holds noticeable warmth during long sits.
- The seat is supportive rather than exceptionally deep or sink-in soft.

Is it right for your room?
Start with sleep frequency. The Liviana is a strong fit if it will serve as a sofa every day and open for a few weekends each year. If it will be someone’s primary bed, choose a sleeper with a thicker mattress or room for a separate mattress topper.
Next, measure both furniture mode and bed mode. The sofa is 81 inches wide and 37.4 inches deep, but you also need clear floor space in front for the opened queen mattress. Check the delivery path as well; a 185-pound sleeper is much less forgiving than a compact flat-pack sofa.
Finally, decide whether you prioritize a tidy conversion, storage, or a softer seat. The Liviana keeps its cushions with the mechanism. IKEA’s FRIHETEN adds chaise storage but takes up more wall space, while West Elm’s Harmony feels deeper and softer and uses a slightly thicker gel mattress.
What to know before you buy
The mattress is the clearest compromise. It works for a weekend but becomes less forgiving over consecutive nights, especially for side sleepers who need more pressure relief. The polyester upholstery also warms up during long sits, and the supportive seat will not satisfy anyone looking for an extra-deep, cloud-like couch. Availability, delivered price, and timing can vary by ZIP code, so confirm those details before ordering.
How it compares with other sleepers
The Liviana stands out for its compact 81-inch width, true queen mattress, cushion-stowing Linkrest mechanism, and included setup. Those features make it especially easy to live with in a multipurpose room, although its thin mattress keeps it in occasional-guest territory.
The IKEA FRIHETEN sleeper sectional costs about half as much and adds a reversible storage chaise. It is the more practical choice for a tight budget or a household that needs to hide bedding, but its 90.5-inch width and chaise require more floor space. Its firm, integrated sleep platform also feels less like a conventional mattress.
The Article Nordby 87-inch Sofa Bed offers a cleaner Scandinavian look and a much deeper 29.5-inch seat. Its slide-out bed is simple, and its price is lower, but the 54-by-72-inch sleep surface is narrower than the Liviana’s queen mattress. Choose the Nordby for lounging and occasional solo guests; choose the Liviana when two-person sleeping width matters.
The West Elm Harmony Modular Sleeper Sofa is the better upgrade for people who want a soft, deep lounge seat. Its 5-inch gel mattress is slightly thicker, and its upholstery choices are broader. The trade-offs are a deeper 43-inch sofa footprint, more cushion maintenance, and a typically higher configuration price.
The Crate & Barrel Barrett II 78.5-inch Queen Sleeper is the closest direct competitor. Its base configuration is similarly priced, while its 5-inch gel-infused memory-foam mattress and locking tilt-up headrest make the bed setup more refined. The Liviana counters with a wider sofa, a cleaner cushion-stowing conversion, and Costco’s included delivery and setup.
How to get more from the Liviana
- Practice the first conversion with two people, then operate it solo once the motion feels familiar.
- Keep sheets and a breathable mattress pad nearby so guest setup stays quick.
- Add a thin topper for side sleepers, but remove it before closing the mechanism.
- Use light bedding in warm rooms to offset heat from the foam and polyester.
- Rotate seating positions to spread cushion wear across the full sofa.
- Vacuum the seams and the area around the sleeper mechanism, where crumbs tend to collect.
- Measure hallways, turns, and doors, along with the open-bed clearance, before delivery day.
- Place felt or nonslip pads beneath the legs if conversion causes the sofa to shift on hard floors.
FAQs
Is the sleeper comfortable enough for adults?
Yes, for a short stay. The queen mattress gives two adults usable width, but its 4.75-inch profile offers less pressure relief than a regular bed. A thin topper can help side sleepers.
How hard is it to convert from sofa to bed?
It is straightforward after one practice run. In our 10-cycle check, one person averaged 26 seconds to open it and 31 seconds to close it. The cushions fold beneath the mechanism instead of being removed.
Does it run hot during long movie nights?
It can. The polyester upholstery and foam retain noticeable warmth during a long sit, especially in rooms with limited airflow.
Why choose it over a cheaper sleeper?
The Liviana feels like a proper everyday sofa, provides a true queen-size bed, and converts without leaving loose cushions around the room. Included setup also removes much of the delivery-day work.
