We Build This Sofa

Product Overview

Low to the ground, endlessly adjustable - a Japanese-style floor folding sofa that goes from cozy seat to flat lounging bed in seconds.

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.

Technical Specifications

Motor Type

None - fully manual and motor-free. A Japanese-style low-profile folding sofa bed with a 5-position adjustable backrest locked by a heavy-duty manual hinge. Because there is no electric motor, no power adapter, and no live wiring, there is nothing to fail, no pinch-point risk, and no power outlet required. The backrest reclines through five detents from upright to nearly flat, and the whole unit folds down to a 15 cm floor profile, making it safe for children's rooms, student housing, and rentals.

Fatigue Testing

The manual backrest hinge and the sofa-to-bed folding linkage are cycle-tested through 25,000 open/close repetitions under a 360 lb (163 kg) static load, with no loosening, no hinge deformation, and no fabric abrasion at the pivot points. The steam-treated eucalyptus frame and 4.5" high-density recycled-foam core (60 kg/m3) are rated for the same 360 lb seated load, and the elastic webbing base is re-checked for sag after every 5,000 cycles.

Certification

As a non-electric furniture item it carries CE furniture-safety compliance and RoHS-compliant material restrictions across all textiles, foams, and hardware; no LVD/EMC testing is required, which simplifies EU customs entry. The E1 plywood keeps formaldehyde emissions low, and the black woven fabric passes SGS abrasion testing while the foam meets GB 8410 fire-retardant requirements.

Customization

Choose from a range of woven fabrics in multiple colors, optional matching lumbar pillows, a choice of backrest angle stops, and compact or extended bed-length dimensions. The split-fold packing is optimized for cross-border containers (181 sets per 40HQ on the related 2P model). Typical lead time is 30-45 days from deposit; contact us for a swatch card and a tailored FOB quote.

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 folding solid wood frame that is lightweight enough to move with one hand, yet sturdy enough to hold firm through daily use.

Eucalyptus hardwood in precision-cut dimensions: 1.9x3.4 cm and 2.4x4.4 cm - used for the main seat rails, backrest supports, and folding joints.

Pine timber (3x5 cm) reinforces the lower base frame for added stability.

Multi-layer plywood (11mm, 17mm) for the base panels and backrest boards that keep their shape through repeated folding.

Japanese-style L-bracket folding hinges (5 positions) - the core mechanism that lets the backrest lock at five different angles, from upright seating to fully flat. The hinge is reinforced with a 70x27x27mm angle bracket for durability through thousands of open-close cycles.

All joints are glued with white wood adhesive and secured with industrial staples and color wood screws for a frame that folds smoothly and stays tight.

Spring System & Base Support

A flexible support system tuned for a low-profile floor sofa - supportive where it matters, soft where you sit.

Elastic Webbing - both 7cm wide (3") and 4.5cm wide green elastic webbing stretch across the seat and back frames, providing flexible, breathable support that adapts to the body.
Steel positioning wire (2.0mm diameter) locks the webbing in place, preventing shift and maintaining even tension across the seat surface.
The low-profile design (seat height just 24 cm) means the support system works close to the floor, distributing weight evenly across the frame for a stable, grounded sit - no sinking, no tipping.

This combination delivers a supportive base that holds up through daily sitting, lounging, and full-body reclining when the sofa is laid flat.

Foam Configuration

High-density foam layering gives the JF-5098 a comfortable sit that keeps its shape for years.

Recycled High-Density Foam (60 kg/m3) - 1" and 1.5" layers form the structural core of the seat and backrest. The extra-high density means excellent compression resistance - it will not flatten out, even with daily use and full-body weight when reclined.
High-Resilience Foam (23 kg/m3) - 0.5" and 1.5" layers provide spring-back comfort and a soft, cushioned feel over the dense core.
"A" Cotton Batting (12 kg/m3) - 3/8" wrapping layers smooth out edges and soften contact points for a plush finish.
Seat surface: 1" recycled foam (55.88x105.41 cm) topped with 0.5"foam - a combination that feels supportive when you sit and comfortable when you lie flat.

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, breathable 240GSM fabric that fits naturally into Japanese-style and minimalist interiors.

Fabric Spec: 240 GSM- a mid-weight textile that is soft to the touch and comfortable against the skin during long lounging sessions.
Breathable & Skin-Friendly - the fabric allows air circulation, keeping you cool and comfortable during extended sitting or lounging.

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

Legs

Ultra-low, anti-slip base feet keep the sofa stable and grounded - true to its Japanese floor-sofa design.

Height: 1 cm (0.4") - essentially a floor-level seat that brings you close to the ground for a relaxed, grounded Japanese seating posture.
Black anti-slip rubber feet on all four corners protect your floor from scratches and keep the sofa from sliding on hardwood, laminate, or tatami.
The low profile creates a clean, minimal silhouette that makes rooms feel more open and spacious.

FAQ

Q: How does the 5-position backrest adjustment work?

A: The backrest locks at five angles using a reinforced Japanese-style folding hinge with a 70x27x27mm angle bracket. Simply lift or lower the backrest to your preferred position and it locks securely in place - from upright seating to a fully flat bed. Adjusting takes seconds and the hinge is built to handle thousands of open-close cycles.

Q: Can it really be used as a bed?

A: Yes. When the backrest is laid flat, the sofa opens to a 180 cm x 70.9" surface - comfortably long enough for a full adult to stretch out, or for two people to sit side by side. The included bolster pillow adds head and neck support for sleeping. It is an ideal spare bed for small apartments and guest rooms.

Q: Is it suitable for Japanese-style rooms and tatami?

A: Absolutely. With a low 24 cm seat height and anti-slip rubber feet that will not scratch flooring, it is designed for Japanese-style interiors, tatami rooms, and low-seating lifestyles. The warm beige tone pairs naturally with wood and tatami.

Q: How do I clean the covers?

A: The seat and backrest covers are removable with quality zippers, so you can take them off and wash them easily. For everyday spills, blot with a damp cloth. The 240GSM fabric is durable and designed for regular cleaning.

Q: How much space does it take up when folded?

A: Very little. When not in use it folds into a slim low profile, and for shipping it packs flat into a compact 104 x 88 x 23 cm carton. It can be tucked against a wall, under a window, or into a closet.

Q: What is the minimum order and lead time?

A: MOQ is 1 x 40HQ container, which loads 278 sets. Standard lead time is 30-45 days from deposit confirmation, depending on order quantity and customization level.

Q: Can I customize the fabric color?

A: Yes. Fabric color can be customized to match your market preferences. Contact our team to request a fabric swatch card and discuss your specific requirements.
