- the rear cushions 28 sealed in vacuum bags 42 , are laid on top of the seat cushions 26 .
- the rear deck 22 is laid on top of seat cushions 26 . Because the seat deck 20 , rear deck 22 , seat cushions 26 , and rear cushions 28 are of equal or nearly equal length and width, they form a uniform or nearly uniform stack.
- a plurality of sewn woven bands 44 are applied to the stack.
- the plurality of bands 44 hold the compressed stack together.
- the contents of the stack tends to expand against the plurality of bands 44 , urging the seat deck 20 and rear deck 22 , which form the outsides of the sandwich assembly, against the bands 44 .
- the woven bands 44 restrain the stack from expanding and keep the seat cushions 26 and rear cushions 28 from decompressing to their original thickness once the external compressive force is removed. It is desirable to use a plurality of woven bands 44 spaced equally across the length of the stack; for example, a set of six equally spaced woven bands 44 has been used to successfully secure a sandwich assembly 40 for shipping. Once the woven bands 44 have been slipped around the stack and each has been placed in the desired location along the stack's length, the external compressive force may be removed.

Shipping container 50 is of sufficiently greater height than sandwich assembly 40 so as to provide space for the remaining components of sofa 10 .
- the rear cushion cover 30 is folded and laid on top of sandwich assembly 40 . Next, arms 12 may be placed, side-by-side, on top of rear cushion cover 30 . Front rail 14 and rear rail 16 may be placed side-by-side on top of arms 12 .
- the remaining components may be sealed in a plastic hardware bag 46 , which may be placed into any available space next to arms 12 , front rail 14 , and rear rail 16 .

Abstract
An easy-to-assemble sofa along with a method of packaging its components so as to consume the smallest possible space during shipping. The sofa includes arms and rails that may be assembled to form a frame. A seat deck and rear deck are installed to the arms and rails. Cushions are placed atop the seat deck, and foam cushions are placed in front of the rear deck to form the sofa's seating surfaces. To conserve space during shipping, the compressible seat cushions and rear cushions are placed between the rigid seat deck and rear deck. The entire assembly is banded with woven bands to maintain it in a compact compressed condition during shipping, which may all be in a single cardboard container. This method of packing allows the parts of the sofa to be packed in as compact a container as possible, saving money on shipping and storage.

- This application claims the benefit of the filing date of U.S. Provisional Application No. 61/443,472, filed Feb. 16, 2011. The entirety of U.S. Provisional Application No. 61/443,472 is incorporated herein by reference.
- This disclosure relates generally to furniture, and more specifically, to an easy-to-assemble sofa and a method of packing the sofa parts together in a highly compact manner.
- Furniture items generally, and sofas in particular, have traditionally been fully assembled in a factory, then shipped to retailers and delivered to the consumer in the fully assembled condition. A fully assembled sofa is bulky and, therefore, a significant portion of the total cost of a sofa sold at retail is the cost of shipping and storage. Presented here is an easy-to-assemble sofa that may be packed into a single, extremely compact, shipping box and assembled either by a retailer or by a consumer after shipping. By packing the sofa in a manner specially devised to conserve space, the cost of shipping is lowered and the amount of warehouse space necessary to store the sofa is reduced. Shipping the entire sofa, including all structural, aesthetic, and comfort-enhancing components, in a single box is convenient for the retailer and the consumer.
- The disclosed devices and methods of use may be best understood by reference to the following description taken in conjunction with the accompanying drawings in which like reference numerals identify like elements in the several figures and in which:
-
FIG. 1 is a perspective, exploded view of an easy-to-assemble sofa of the present disclosure; -
FIG. 2 is a perspective view of the sofa ofFIG. 1 , fully assembled; -

FIG. 4 is a side perspective view of selected sofa components packed for shipping; -
FIG. 5 is a side perspective view of selected sofa components packed for shipping; and -
FIG. 6 is an exploded perspective view of sofa components being packed in a container for shipping. - The easy-to-assemble
sofa 10 of the present disclosure, illustrated inFIG. 2 , is shipped unassembled in order to make it more compact during shipping, with all unassembled components fitting within a single rectangular cardboard box. The components of thesofa 10 are sized and arranged so that they may be fit into as compact a container as possible. Additionally, certain techniques are employed to save additional space when the sofa components are packed for shipping. An exploded view of the components ofsofa 10 is illustrated inFIG. 1 , and a cross-sectional view of an assembledsofa 10 is illustrated inFIG. 2A . - The
sofa 10 has twoarms 12 which form the ends of the completedsofa 10. Each of thearms 12 is a minor image of the other, such that eacharm 12 has an outward-facing surface, and an inward facing surface that faces the inward facing surface of theopposite arm 12 when thesofa 10 is fully assembled. The inward facing surface of eacharm 12 connects to an end of afront rail 14 near the front edge of eacharm 12, and to an end of arear rail 16 near the rear edge of eacharm 12, so as to form a rectangular shaped frame when viewed from above. - The
front rail 14 may be provided with a pair of L-shaped brackets includingmounting plates 13 extending perpendicular to the axis of thefront rail 14, one of themounting plates 13 extending from either end of thefront rail 14. Each of themounting plates 13 has at least two keyhole-shaped openings 15 therethrough to securely receive bolts projecting inwardly from thearms 12. Thefront rail 14 may be provided withrecessed portions 17 at the ends, to which a portion of the L-shaped brackets extending perpendicularly to themounting plates 13 may be secured, in order to minimize the extent to which themounting plates 13 project beyond the maximum thickness of thefront rail 14, thereby facilitating compact packaging of the sofa components. - The
arms 12,front rail 14, andrear rail 16 are preferably built with an internal frame composed of a rigid material such as metal or wood, and are upholstered on their exterior. Foam or other padding may be included below the upholstered outer surfaces ofarms 12,front rail 14, andrear rail 16, if desired, to enhance appearance and/or comfort. Alternatively or in addition to upholstery, thearms 12,front rail 14, andrear rail 16 may include exposed solid surfaces, such as finished wood, for decorative purposes. Threaded fasteners (not shown) may be used to attach thefront rail 14 andrear rail 16 to thearms 12. - Four or
more legs 18 may be provided, if desired, to stand thesofa 10 off of the floor.Legs 18 are mounted to the bottom surface ofarms 12,front rail 14, orrear rail 16, but most preferably, twolegs 18 are installed to the bottom surface of each of thearms 12 near the four outer corners of thesofa 10. As illustrated inFIG. 1 , threaded fasteners extending from the tops oflegs 18 may be used to firmly attach thelegs 18 to the bottom surface ofarms 12. - A
center brace 19 is securable, such as by threaded fasteners, to upper central portions of thefront rail 14 and therear rail 16. The center brace adds stability and transmits vertical loads from theseat deck 20 to the front andrear rails 16, and ultimately to thearms 12 andlegs 18. - The
seat deck 20 andrear deck 22 are each comprised of a substantially rectangular, rigid metal outer frame with rigid cross-members spaced at equal intervals within the outer frame, the cross-members being substantially parallel to the short sides of the rectangular outer frame. Both the outer frame and cross-members ofseat deck 20 andrear deck 22 are preferably constructed of tubular steel. The rigid metal outer frame comprisingseat deck 20 andrear deck 22 includesholes 23 in various places to accept threaded fasteners. Preferably, theseat deck 20 is adapted to receive a single bolt 25 (or similar threaded fastener) through each of twoholes 23 for securement torespective seat brackets 36, one of whichseat brackets 36 is mounted on each of thearms 12. Theseat deck 20 andrear deck 22 may be of any size and shape to create a particular style or design of sofa, but are preferably rectangular and of the same size and shape. If desired, theseat deck 20 andrear deck 22 may be identical, though preferably, therear deck 22 is secured to each of tworear brackets 24 mounted to thearms 12 by a pair of bolts or other threaded fasteners, as opposed to thesingle bolt 25 or other threaded fastener employed to secure theseat deck 20 to eachseat bracket 27. - A plurality of
strap bands 21, made of a webbing of a fabric material, a non-woven material, hook-and-loop fastener material, or other material with noise-dampening characteristics, are preferably attached to theseat deck 20, in a direction perpendicular to the cross-members of theseat deck 20. Thestrap bands 21 serve to dampen undesirable sound that may otherwise occur when one sits on thesofa 10. Thestrap bands 21 may be attached to theseat deck 20 prior to shipment, or alternatively, if theindividual strap bands 21 are continuous, they may be installed during assembly of thesofa 10 by slipping them over a side of theseat deck 20, as illustrated inFIG. 1 . If the strap bands are discontinuous, each may be secured lengthwise about theseat deck 20. Theindividual strap bands 21 may be coiled, as illustrated inFIG. 6 , so as to be compact for shipment. -
Rear deck 22 is fastened to thearms 12 using two or morerear brackets 24. Therear brackets 24 have an L-shaped cross-section with a 90 degree bend at their center, holes to receive one or, preferably, two bolts (or similar threaded fasteners) to secure therear deck 22 to thearms 12, and therear brackets 24 are preferably made of steel. One plate of eachrear bracket 24 mounts flush against the inward-facing side of eacharm 12 such that the other plate of therear bracket 24 extends inward fromarm 12. Threaded fasteners (not shown) are used to mount therear brackets 24 to the inward facing surfaces ofarms 12, and to mount therear deck 22 to therear brackets 24. As illustrated inFIG. 2A , therear brackets 24 may be mounted against the inward facing side ofarms 12 so as to hold therear deck 22 vertical, or more preferably, they may be angled, such as at an angle α in the range of 95 degrees to 105 degrees from a horizontal plane, so as to hold therear deck 22 in a slightly reclined position. Theseat brackets 36 are also formed of L-shaped steel brackets, with the plates that face theseat deck 20 being preferably slanted at an angle θ in the range of 5 degrees to 20 degrees from a horizontal plane so that the seating surface is somewhat reclined from the horizontal plane. Theseat brackets 27 andrear brackets 24 provide for accommodation of a variety of sofa styles, thereby providing a modularity, with the ability to select among a plurality of different sizes and types of sofa components to be packaged and shipped in a single box. - Like the
rear deck 22, theseat deck 20 is also fastened to the inward facing surfaces ofarms 12. One ormore seat brackets 36 are mounted to the inward-facing surface of eacharm 12. Theseat brackets 36 are L-shaped metal brackets with a 90-degree angle, and have one or more holes to receive threaded fasteners on either side of the bend. Theseat brackets 36 are preferably identical in construction to therear brackets 24 to simplify manufacturing and reduce costs. One side of each seat bracket is mounted flush against the inward facing surface of eacharm 12 using threaded fasteners (not shown). The other side of eachseat bracket 36 extends inward from the inward facing side ofarms 12, and provides a supporting surface forseat deck 20. Theseat deck 20 is placed between thearms 12 such that theseat deck 20 rests upon thefront rail 14 and theseat brackets 36. Theseat deck 20 is then attached to theseat brackets 36 and, if desired, to thefront rail 14, with threaded fasteners (not shown) to hold theseat deck 20 in place. Theseat brackets 36 may be mounted so as to hold theseat deck 20 parallel to the floor, or preferably may be mounted slightly lower than thefront rail 14 to decline the seat deck slightly, as illustrated inFIG. 2A . - To form the seating surfaces of the
sofa 10, one or more seat cushions 26 are placed atop theseat deck 20 to provide the seating surface of thesofa 10. Oneseat cushion 26 of approximately the same length and width as theseat deck 20 may be employed, or alternatively, two or more seat cushions which may be placed side-by-side so as to completely cover theseat deck 20 may be employed instead. The one or more seat cushions 26 may be of foam or of a coil-spring design as is well known in the art, and are covered with upholstery. The sofa also includes one or more rear cushions 28. Like the seat cushions 26, onerear cushion 28 of approximately the same length and width as therear deck 22 may be employed, or alternatively, two or morerear cushions 28 which may be placed side-by-side so as to completely cover therear deck 22 may be employed instead. The one or morerear cushions 28 are made of a polyester fiber material, sized to approximately cover therear deck 22 when installed.Rear cushion cover 30 is made of upholstery material and includes onecushion pocket 32 for eachrear cushion 28 in its front face. Eachcushion pocket 32 holds arear cushion 28 within. Therear cushion cover 30 also includes adeck pocket 34. Thedeck pocket 34 is on the rear face ofrear cushion cover 30, and its opening faces downward. One or morerear cushions 28 are placed within the cushion pocket(s) 32 ofrear cushion cover 30. Next, thedeck pocket 34 ofrear cushion cover 30 is lowered onto the sofarear deck 22. If desired, snaps, hook-and-loop fasteners, zippers, or some other device may be used to affix the upholstery ofrear cushion cover 30 to thearms 12 and/orrear rail 14 ofsofa 10 once therear cushion cover 30 has been slid over the top ofrear deck 24. - Both the seat and rear cushions, by nature, tend to be highly compressible, and therefore, certain techniques such as those disclosed herein may be employed to assemble them into the most densely packed assembly possible for shipping.
- The rear cushions 28 are made with a highly compressible polyester fiber. To prepare them for shipping, the
rear cushions 28 may be sealed in air-evacuable bags, also known asvacuum bags 42, which are commonly available. As air is evacuated from thevacuum bags 42, therear cushions 28 are compressed and reduced in thickness. Once all evacuable air has been removed from thevacuum bags 42, the bags are sealed and therear cushions 28 remain compressed within for shipment. When the sofa parts are unpacked from their shipping container for assembly, thevacuum bags 42 are opened by the customer and therear cushions 28 are removed. Experience has shown that the polyester fiberrear cushions 28 do not return completely to their original thickness once removed fromvacuum bags 42 for installation into the completedsofa 10; typically, a polyester fiberrear cushion 28 will only return to about two-thirds of its original thickness once removed fromvacuum bag 42. Therefore, it is preferable to make therear cushions 28 about 50 percent heavier than would otherwise be necessary so that therear cushions 28 are of appropriate size at the time of unpacking and assemblingsofa 10. - Several parts of the
sofa 10 are then assembled into asandwich assembly 40 for shipping. An example of a suitable sandwich assembly is illustrated inFIG. 3 . First, theseat deck 20 is laid down, then the coil seat cushions 26 are laid down on top of theseat deck 20. The rear cushions 28, sealed invacuum bags 42, are laid on top of the seat cushions 26. Therear deck 22 is laid on top of seat cushions 26. Because theseat deck 20,rear deck 22, seat cushions 26, andrear cushions 28 are of equal or nearly equal length and width, they form a uniform or nearly uniform stack. - A plurality of sewn
woven bands 44 are applied to the stack. The plurality ofbands 44 hold the compressed stack together. The contents of the stack tends to expand against the plurality ofbands 44, urging theseat deck 20 andrear deck 22, which form the outsides of the sandwich assembly, against thebands 44. - In other words, the woven
bands 44 restrain the stack from expanding and keep the seat cushions 26 andrear cushions 28 from decompressing to their original thickness once the external compressive force is removed. It is desirable to use a plurality ofwoven bands 44 spaced equally across the length of the stack; for example, a set of six equally spacedwoven bands 44 has been used to successfully secure asandwich assembly 40 for shipping. Once thewoven bands 44 have been slipped around the stack and each has been placed in the desired location along the stack's length, the external compressive force may be removed. - The completed
sandwich assembly 40 may be placed inshipping container 50 for shipping, as shown inFIG. 4 . Shippingcontainer 50 may be constructed of any suitable material, such as wood or corrugated cardboard. Shippingcontainer 50 is of length and width approximately equal to or slightly greater than thesandwich assembly 40 such that thesandwich assembly 40 may be lowered inside with slight clearance around its edges. Shippingcontainer 50 is of sufficiently greater height thansandwich assembly 40 so as to provide space for the remaining components ofsofa 10. Therear cushion cover 30 is folded and laid on top ofsandwich assembly 40. Next,arms 12 may be placed, side-by-side, on top ofrear cushion cover 30.Front rail 14 andrear rail 16 may be placed side-by-side on top ofarms 12. The remaining components, including therear brackets 24,seat brackets 36,legs 18, all necessary threaded fasteners (not shown), and assembly instructions, warranty information, or other printed materials, may be sealed in aplastic hardware bag 46, which may be placed into any available space next toarms 12,front rail 14, andrear rail 16. Theshipping container 50 may then be closed and sealed for shipping. - Those skilled in the art will appreciate that, although the teachings of the invention have been illustrated in connection with certain embodiments, there is no intent to limit the invention to such embodiments. On the contrary, the intention of this application is to cover all modifications and embodiments fairly falling within the scope of the appended claims either literally or under the doctrine of equivalents.
