The key product quality considerations when purchasing an upholstered product are:
An upholstered product frame needs to be judged on strength, the ability to absorb punishment and
proportion design to insure a comfortable and long lasting support structure for the suspension and
Frame construction can vary from air dried plywood, which is glued and stapled, to kiln dried hardwood
which is glued, doweled and corner blocked.
Shoreline Upholstery is constructed of 7/8" kiln dried hardwoods. All components are precision cut on
computer controlled machine tools for precision and repeatability. All wood joints are interlocked,
glued, and reinforced with corner blocks to provide long term strength and durability.

The upholstered product suspension system is designed to tie into the frame and provide a solid,
consistent and long lasting support system for the cushions.
There are 4 general support systems used:
Drop In Coil
Eight Way Hand Tied
Eight Way Hand Tied is the oldest system, is considered the best by many and is the most expensive.
The purpose of tying the springs 8 ways (up, down and on the diagonals) is to insure all of the springs
Drop In Coil is a pre-assembled, machine-made and machine-tied coil system which has been growing
in popularity as a very durable and cost effective method to achieve the performance of a traditional 8
way hand tied system without the expense.
Shoreline products use a high quality Drop-In Coil Unit as a standard as it provides an excellent
balance of comfort, durability and cost. We also offer an Eight Way Hand Tied option for a 7-9% up
The construction of the cushions is critical to the comfort and useful life of any piece of upholstery. The
general categories of seat cushions are:
Low Density Raw Foam
Wrapped High Density Foam
Polyurethane foam is the major component to most upholstered seat cushions. Foam is measured by
density, firmness and resiliency. Foam density measures the amount of foam per cubic foot. The higher
the foam density the heavier and better quality the cushion. Higher quality seat cushions have a density
of 1.8 pounds per cubic foot. Firmness measures the weight it takes to compress the foam one inch and
can vary regardless of the foam density. Firmness is key to engineering a comfortable cushion and will
vary from 20-35 pounds for a seat cushion and 10-20 pounds for a back cushion. Resiliency measures
the ratio of the weight to compress foam 1” and 2.5”. The higher the resiliency, the higher the quality and
the longer lasting the seat cushion. Higher resiliency foams allow the use of softer and plusher foam
(lower firmness) and still have the deep down support required for long lasting high quality seat cushions.
Wrapped High Density Foam seat cushions include a polyurethane foam core which is then wrapped
with polyester fiber or a feather blend to provide a crown to the seat cushion and a softer cushion surface
Blend Down is another option for seat cushions. This cushion is constructed completely of a blend of
fiber, feathers and down. This is a premium construction which will supply a very cushy, soft feel. This
type of cushion does require fluffing and turning to maintain appearances.
Another premium seat cushion construction is Spring Down. This construction includes a pocketed
coil core encased in foam and then wrapped in a feather down blend. This seat cushion provides a
slightly firmer support while maintaining a soft surface comfort.
The standard Shoreline seat cushion is a 1.8 density high resiliency foam core wrapped in a soft
polyester fiber and encased in a down proof ticking cover. The back cushions are channeled polyester
fiber encased in a down proof ticking cover. These cushions offer a 10 year resiliency warranty.
The standard Shoreline Accent chair seat cushion is 1.8 density high resiliency foam wrapped in a
channeled feather blend (50% soft polyester fiber, 45% duck feather, 5% duck down) and encased in
a down proof ticking cover. The back cushions are channeled feather blend encased in a down proof
ticking cover. These cushions offer a 5 year resiliency warranty.
The feather blend cushions are also available on other Shoreline products for approximately a 20%
up charge. The feather blend package includes seat cushions, back cushions and throw pillows.
An environmentally friendly spring down cushion package is also available for Shoreline products for
approximately a 25% up charge. The seat cushion consists of a pocketed coil core encased in a soy
based 1.8 HR foam wrapped in a eco feather blend (50% regenerated fiber, 45% duck feather, 5% duck
down) encased in a 100% cotton cover. The back cushions are made of a channeled eco feather blend.
These cushions offer a 5 year resiliency warranty.
Fabrics are the fun part of an upholstered product as they provide the opportunity to use a wide range of
colors, patterns, style and durabilities to fit each individual requirement.
Fabrics can be applied as either upholstered, which are applied directly to a padded frame, or
slipcovered, which are separate covers fit over a separate muslin covered frame. Upholstered products are
usually a little more tailored looking and can offer more design options. Slipcovers offer the easier
cleaning and the option of replacing the fabric without the cost of replacing the complete piece.
Slipcovers are often more expensive.
Standard fabrics are offered in a variety of grades with the higher grades at higher costs. A fabric grade is
determined by the type of material (cotton, polyester, linen, silk), the pattern (solid, print, stripe, plaid)
and weight of the fabric. Usually, upholstered and slip covered products can also be made with fabric
supplied by the customer (COM).
Shoreline products are available upholstered or slipcovered at the same cost. Standard slipcovers are
computer cut and hand sewn.
The price of the piece is determined by the grade of the fabric. A contrast welt and throw pillows are
available in any fabric at no additional charge. Collage (multiple fabrics) slipcovers are available at an
additional charge based on the number of different fabrics used in the design. Shoreline products can
also be made with COM (customer’s own material) fabrics but are only washable if the fabric has been pre-
Shoreline fabrics tend to be durable cotton, polyester and outdoor fabrics which work well in a
slipcovered construction. Although it is recommended to have slipcovers dry cleaned to insure long
life, many of the fabrics have been pre-washed which allow the slipcovers to be machine washed.
Slipcovers also include fit allowances to support washable slipcovers. (see Washing Instructions) Dry
Clean Only fabrics and slipcovers with contrast welts are not suitable for machine washing.
