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 is safe and avoid product liability issues. 2

3 Is all commercial furniture the same? Intended use Price vs features Expected lifespan Raw materials Shifts per day Demographics Maintenance programs 3

4 Form follows function. Louis Sullivan 4

5 How is comfort achieved? 5

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

7 Geometry 7

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

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. 9

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

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

12 Types of Seats SPRING FOAM SEAT & SINUOUS SPRING FOUNDATION Webbing SINUOUS SPRING SEAT 12

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

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 14

15 Suspension Systems ILD/IFD ILD Indention Load Deﬂection also known as compression or Indention Force Deﬂection Measure the softness of the material by compressing the foam by a % using a 50 square inch disc. -Average seat is Firm seat is Very thin seats my be up to

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

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 17

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

19 THE 6 F S 19

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

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

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 22

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.

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. 23

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

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, minimum shipping charges Distance drives cost Cost per mile Risk of damage Type of packaging required, both material and labor Cost of unpacking and waste removal 25

ﬁnest raw materials and highly detailed workmanship.

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? 26

Create a maintenance schedule and document it 2.

27 Liability in today s world Cost of Product Liability: Time Money Reputation 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 27

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 28
