We Build This Sofa

Product Overview

Smart storage, instant sleeper - a compact storage sofa that gives small spaces big functionality.

Below is exactly how our factory builds it - the raw materials, the internal construction, and the QC steps we run before it ever leaves the workshop.

Ideal for: small apartments, studio lofts, guest rooms, home offices, RV living, dorm rooms, and any space where seating, storage, and sleeping need to share one footprint.

Technical Specifications

Motor Type

None - manual convertible plus gas-assisted storage lid. A compact 2-seat storage sofa bed in pure black fabric; the sofa-to-bed conversion and the storage-lid opening are both manual, so there is no motor to service and no power cable required. Upright size is 117x76x71 cm with a low 30.5 cm seat height, built for micro-apartments, studios, guest rooms, and RV living.

Fatigue Testing

The manual folding linkage and the split spring hinges on the storage lid are cycle-tested through 25,000 open/close repetitions under a 360 lb (163 kg) load, with the 4.5" high-density recycled-foam core (60 kg/m3) retaining its shape. The steam-treated eucalyptus-and-E1-plywood frame stays silent under both seated and lying load, with elastic webbing across the seat base.

Certification

Non-electric, so it carries CE furniture-safety compliance and RoHS-compliant material restrictions. The E1 plywood keeps formaldehyde emissions low, and the 240 GSM black fabric passes SGS abrasion testing - a durable, low-emission choice for short-term rentals and student housing.

Customization

Choose the black fabric or a different colorway, add the armrest storage pocket (standard), choose between sofa-only or sofa-plus-included-mattress configuration, and specify the storage compartment layout. Loading is 181 sets per 40HQ. MOQ is 1 x 40HQ; lead time 30-45 days.

Built for daily contract and residential use, every unit is assembled and QC-checked in our ISO-certified Huizhou factory - incoming material inspection, frame and hardware assembly, spring and foam lay-up, upholstery fit, and a full functional test on the reclining mechanism (where fitted) - before soft-pack export. Each piece leaves with bubble wrap, non-woven fabric, corner guards, and desiccant packs in a K=A carton. Typical lead time is 30-45 days from deposit confirmation, depending on configuration and order volume. Contact us for a swatch card, CAD drawings, and a tailored FOB quote for your project.

Frame

A sturdy solid wood frame built from steam-treated eucalyptus hardwood and E1-grade plywood - lightweight enough for small spaces, strong enough for daily use.

Steam-treated eucalyptus hardwood (density 0.39 T/m3, finished 1.8x3.3 cm from rough 2.5x4 cm) - used for the main frame rails, armrest structure, and screen (backrest) supports.

E1-grade plywood (12mm, 9mm, 5mm) - the storage compartment walls, base panels, and backrest boards. E1 grade means low formaldehyde emission, meeting strict indoor air quality standards.

All joints are glued with white wood adhesive and secured with industrial staples and four-prong T-nuts (M6) for a frame that stays solid and silent.

The storage compartment is integrated into the frame structure with split spring hinges (18.5cm x 12cm, left/right paired) that hold the lid open securely and close smoothly.

Spring System & Base Support

A webbing-and-dense-foam support system engineered for a compact storage sofa - firm, stable, and built to hold both sitting and sleeping weight.

Elastic Webbing - 4.5cm wide green elastic webbing stretches across the seat frame, providing flexible, breathable support that adapts to the body.
Dense Foam Core - the seat uses a thick 4.5" high-density recycled foam core (60 kg/m3) that provides excellent compression resistance - the structural "spring" of this sofa, holding firm through both seated use and full-body reclining.
Spring Hinges - the storage lid is supported by split spring hinges that keep it open at a stable angle and close gently, so the mechanism is smooth and durable through thousands of open-close cycles.

This combination delivers a stable, grounded sit with no sinking or tipping, even when the sofa is fully extended as a sleeper.

Foam Configuration

High-density foam layering gives the JF-5055-2P a supportive, long-lasting sit that doubles as a comfortable sleeping surface.

High-Density Recycled Foam (60 kg/m3) - 4.5" thick core for the seat (42x39.5 cm) and backrest (39.5x36 cm). The extra-high density resists compression and permanent indentation, keeping its shape through daily use.
Medium-Soft Foam (18 kg/m3) - 2" layers on seat fronts, sides, and backrest edges for a soft, cushioned edge that prevents "roll-off"; 5" layers on the seat rear and backrest base for deep support.
Recycled Foam (50 kg/m3) - 1" layer on the armrest top for a comfortable, durable arm surface.
"A" Cotton Batting (12 kg/m3) - 3/8" and 1/2" wrapping layers smooth out edges, soften contact points, and protect the foam inside the covers.
Storage lid: 0.5" A-cotton padding over the plywood lid for a soft, finished surface.

Every foam batch undergoes incoming inspection at our factory - we verify density and thickness before cutting, so you get the specified firmness on every single unit.

Fabric

A soft, durable 240GSM fabric that fits naturally into modern, minimalist, and Scandinavian interiors.

Fabric Spec: 240 GSM, effective width 145 cm - a mid-weight textile that is soft to the touch and comfortable against the skin during long sitting or sleeping sessions.

Fabric is swappable for project orders - contact us for a swatch card and custom color options.

Legs

Ultra-low, anti-slip feet keep the sofa stable and grounded - true to its low-profile space-saving design.

Height: 1.5 cm (0.6") - a low, stable base that keeps the sofa firmly planted and the overall profile compact.

Black anti-slip rubber feet (no-screw, non-marking) on all corners protect your floor from scratches and keep the sofa from sliding on hardwood, laminate, or tile.

The low profile creates a clean, minimal silhouette that makes small rooms feel more open and spacious.
