2 Objectives Develop an understanding of how high quality commercial seating is built for safety and durability. Learn what makes a chair comfortable. Understand what drives the cost of the furniture. Create an environment for owners and end users that are safe and avoid product liability issues.

3 Is All Commercial Furniture the same? Intended use Expected lifespan Shifts per day Maintenance programs Price VS. Features Raw materials Demographics

4 Form follows function. Louis Sullivan

5 How is comfort achieved? shelbywilliams.com

6 How is comfort achieved? How comfortable do you expect furniture to be? Comfort is driven by two factors:

7 Geometry

8 Seat Height Counter Height & Bar Height Stools: 24" vs. 30" Eye Contact improves Counter height is easier to access

9 Geometry As stated by Henry Dreyfuss and Associates in the Measure of Man and Woman, Human Factors in Design: Seating must have specific dimensions to be comfortable and appropriate.

10 Suspension Systems for for Seating Seating When designing or specifying seating, one must consider: Cost Durability Actual Use Life Space Fire Codes

11 Suspension Systems for for Seating Seating Four Types: Spring Foam on deck Webbing Strapping

12 Types of of Seats SPRING FOAM SEAT ON DECK FOAM SEAT & SINUOUS SPRING FOUNDATION SINUOUS SPRING SEAT

13 Suspension Foam is a major component of most suspension systems. Two important measures of foam quality: Density & ILD FOAM SEAT & SINUOUS SPRING FOUNDATION

14 Suspension Density Direct measure of quality How much a cubic foot weighs Minimum commercial standard for a seat is 1.8 lbs. Weight is created as a ratio between material and air

15 Suspension Systems ILD ILD (Indention Load Deflection also known as compression) Does not relate to cost or quality, strictly comfort Measure the softness of the material - Banquet Seating: Up to 65 lbs - Sofa: Low as 30 lbs

16 Foam is is a Common Component Seating will often use several types of foam depending on where it will be used: Why? For example, a seat back will require a lower density and ILD than a seat. Foam can be layered with different types of foam or fiber material, like Dacron.

17 Quiz You have two sample chairs sitting in your office. How would you be able to tell the difference? Why does it matter? Chair #1: 2.3 Density 45 ILD Seat Chair #2: 1.4 Density 45 ILD Seat shelbywilliams.com

18 Furniture cost Costs What are the cost drivers in furniture?

19 The 6 F s

20 Fabric What is the real cost? Fabric A yard is not always a yard. Yield is what matters. Waste caused by repeats Where is it made vs the furniture? Flame retardant?

21 Frame Mortise and Tenon Dowel Joints Corner Blocking Species types Joinery Corner Blocking Finish types Glides, casters Solid vs glue up

22 Frame Type of construction: - Solid wood vs veneer - Solid wood vs the glue up process - Engineered board, such as core or plywood Bentwood vs cut wood Species Wood Quality Construction systems Solid Wood, glue up, plywood

23 Frame The wood industry is governed by the National Hardwood Lumber Association. They set the standard for the number of defects and color range of lumber. These ranges set raw material costs for vendors. The lower the rating, the lower the cost. Generally, it is more costly to manufacture a table or chair in natural than in a walnut stain. Grades of wood: FES, Common 1, Common 2 There can be as much as 100% difference in material cost between FES and Common 2 Wood quality can impact cost as it relates to finish. Often lower, darker finishes will allow a manufacturer to use lower quality wood shelbywilliams.com

24 Finish Wood finish Nitrocellulose Polyurethane Conversion Varnish Ultra Violet Why does a manufacturer choose one finish over another? Number of steps Environment Dry time Ease of repair Durability

25 Freight An enormous percentage of the final cost: Inbound freight getting materials to the factory Outbound freight from the factory to the client Freight included programs LTL vs truck load Distance drives cost Cost per mile Risk of damage Type of packaging required

26 Franchise Big name designers may earn large royalties which impact price These products usually deliver, the finest raw materials and highly detailed workmanship. How might a knock off not live up to your expectations?

27 Liability in today s world Important steps owners should take: 1. Create a maintenance schedule and document it 2. Inspect the furniture on a regular basis 3. Remove broken items or repair When can a designer be liable?

28 Closing Develop an understanding of how high quality commercial furniture is built for durability Learn different methods that make seating comfortable Understand what drives the cost of furniture How to avoid liability and create a safe installation for your client
