Let us show you “The Right Way to Make a Chair!”
We examine 15 points of safety, support, durability, and strength that go into the manufacturing of all our seating products. From the frame to the fabric, we know the true value of quality. Who says they don’t make it like they used to? We won’t do it, unless it’s done “Right!”

1. Fire Codes Carstone is proud to have passed California TB 133, TB 117 and Boston rigorous fire codes for our chairs. If your local government requires this stringent conformity for your safety, please consult Carstone for details.	ours	theirs
2. Hi Density Fire Retardant Foam We only use commercial grade, high density, pure urethane foam in our products. It is highly supportive. Unlike others, we don't add fillers to artificially increase the weight specification. Our foam is fire retardant and will not support or maintain a flame by itself. (Their foam will burn freely creating an extreme fire danger. The 25 pound weight also shows how easily it collapses.)	ours	theirs
3. Welded Bookracks Carstone has perfected this popular option. The wire ends of the rack are not exposed. They are inserted into the leg support tubes to prevent rough edges form damaging clothing and hosiery. (The competition leaves a shaper edge exposed.) Back to top	ours	theirs

4. Full Loop Back Carstone utilizes a full loop of steel to support the chair back. This locks the back together, maintaining frame integrity. (Their frame uses a double post back which allow the posts to flex independently. This movement transfers stress to the fastening hardware ultimately resulting in failure.)	ours	theirs
5. Seat Support & Truss Design Carstone incorporates a tubular steel support bar under the seat, creating a steel seat foundation. Furthermore, we create and engineered truss structure with the seat bar, leg bars and box welds that locks the frame firmly in shape. All stresses are transferred and shared among multiple joints, preventing any one from becoming a hinge joint. (Their frame is void of any additional support through the center of the chair. There is no truss created to strengthen the frame.)	ours	theirs
6. Leg Support Tubes You won't find a simple, side welded wire in our frames. Neither will you find a tube welded on just one edge. We use the full strength of a structural tube to further support our legs. This tube gives beam strength and is 180° butt welded for superior strength. Back to top	ours	theirs

7. Fabrics Carstone offers a full range of extremely high wear fabrics from which to choose. They meet building and fire codes for your safety. Please see our Colors for details.
8. Foot Glides We use a booted, internal spring clip fastened, swivel vinyl glide as standard on our chairs. The boot encloses the end of the tube. (The rounded, friction fit piece of plastic on others does not cover the sharp, rough steel edge of the leg. This sharpness can be seen where plastic has been shaven off the glide when it was inserted.)	ours	theirs
9. Powder Coating The colorful coatings on every Carstone chair is environmentally friendly powder-coating. This coating is far superior to wet epoxy paints that depend on simple "drying" or out-gassing of volatile organics to cure. It is created by a polymerization reaction which forms permanent atomic cross links within the coating and binds to the metal substrate for a most durable finish. (And unlike others, we actually coat the entire chair, even the bottom!)	ours	theirs
10. Low Profile Stack Buttons We use a shallow, inconspicuous button to support the chair in stacks. This lowers the risk of them being knocked out in use and keeps your chair looking like furniture, not like a display rack. (You won't find huge, ugly buttons protruding from our chairs.) Back to top	ours	theirs

11. Steel Composition Carstone certifies all steel used in the structure of its chairs to conform to ASTM A-513 grade C-1010 steel. This is a significantly stronger and higher quality steel than that used by our competitors. We don't need to make up for lesser steel by using a heavier gage and heavier weight. (An example of poor steel is shown. This competitor's chair leg was broken by bare hands, without tools!)	ours	theirs
12. Steel Size Our 1" square steel tubing equals a full 33% greater wall support. Our 13/16" square steel tubing equals 8.5% greater wall support. (The competition steel size is typically 3/4" square steel tubing.)
13. Box Welds Carstone welds on both the top and bottom of the leg to back loop bars. This prevents the joint from becoming a hinge point under stress. In addition, we have extra welds on the seat bar/back loop/ leg junction. (The competitor's joint can flex and open under stress. There are no top welds to lock the frame. Our welds are highlighted in yellow.)	ours	theirs
14. Mandrel Bends Carstone makes its bends with a mandrel in the tube which prevents the wall from collapsing as it is wrapped around the tooling. This makes for a cleaner, more attractive piece of furniture. (Others either chop the tube and kink it, or twist it around the tooling without support, allowing it to cave in.)	ours	theirs
15. Cushion Foundation Engineered wood products and steel seat bars support our cushions. These wood products are designed by creating a multi layer beam configuration for superior screw holding and flexion/torsion resistance as used in the construction industry. (Their cheap wood can break easily.) Back to top	ours	theirs
