The Planar Chair
The Planar offers a functional and subtle elegance with simple but pleasing lines. A thin common frame allows for greater seat size and increased comfort. A slim chair profile permits the architect to increase capacity without sacrificing comfort or proper egress space. The Planar is available with upholstered inner seats and backs with outer veneer, laminate, or powder coated panels. A wide variety of back shapes are available to complement any type of interior design.
The following model is available:
Planar A1: Equipped with inner upholstered seat and back cushions, as well as outer wood veneer panels (with finished plywood edges) for acoustical quality and refined appearance. Customized detailing on the backrest upholstery of the outer wood panels is optional.
- Gravity seat mechanism insures that the seat will always quietly return to a consistent vertical position.
- Hardwood armrests are available in a variety of species and finishes.
- Durable powder-coat finish is standard on all steel components.
- Flush mounted floor attachment hardware is standard.
- A variety of back shapes make this a uniquely versatile chair.
- Veneer, laminate, and powder-coated finishes are available on the outer seat and back panels.
- Standard spacing is 19″, 20″, 21″, and 22″ c.c. of frames (19″ not available with tablet arm).
- Lifetime Warranty is standard on the Planar.
Gravity Tip-Up Seat
The Planar seat tip-up action is attained by the use of a gravity counterweight mechanism. The advantages of a gravity mechanism over a spring or cylinder mechanism are as follows:
Consistent and automatic return to the upright position. Spring mechanisms can have inconsistent tip-up action due to the variation of the strength or fatigue of the steel springs. This affects the aesthetics of the room and may affect compliance with egress codes since the seats may not return to a consistent upright position.
Silent action. Spring mechanisms are likely to develop squeaks and normally produce several loud hits before coming to a stop.
Seat tip-up will never fail. Because the Planar mechanism relies on gravity, it will never fail to return the seat to its upright position. In contrast, as a spring mechanism fatigues, the seat tip-up action will get slower. Eventually, the spring mechanism may fail to return the seat to the upright position, producing a possible violation of egress codes.
The Planar seat construction is patterned after office chairs for long-term comfort and durability. Flexible polyurethane foam is glued directly to the structure of the seat. The advantages of this type of construction are as follows:
Silence, durability, comfort. Seats constructed with serpentine springs often fatigue, sag and fail. This creates an uncomfortable and noisy seat, which may require replacement. TSI’s flexible polyurethane foam construction offers significant user comfort over long seating periods. Additionally, the absence of steel springs insures completely silent compression during use.
Upholstered options. Unlike metal seat pans with serpentine springs, Planar’s all-wood construction allows for custom upholstery detailing. The fully-upholstered seat has a zippered slip-on fabric cover for easier on-site replacement.
TSI Chair Frames
The frames are welded assemblies of heavy gauge and solid steel components. The advantages of this type of construction are listed below:
The Planar frames are welded assemblies of heavy gauge and solid steel components. The Planar’s welded steel assembly allows for simple and cost efficient design modifications for conformance to unique building conditions. Unlike high-volume castings, welded construction facilitates small production run modifications.
Cost of Ownership
Due to the obvious product advantages of Planar seating as mentioned above, and the superior service and warranty levels offered by TSI, purchasing Planar seating is a better long-term value. The initial savings associated with the purchase of a less expensive chair is likely to be lost through ongoing maintenance and replacement during the lifetime of the product.

Use the Planar Floor Mounting Details drawing as reference for the following instructions.
- Use approved floor plan to establish hole locations for the foot plates. Note that the chair radius line coincides with the front hole on the foot plate. Accurate center-to-center width spacing is critical to a proper installation. Tolerance on the chair width dimension is plus or minus 1/8″. It is critical not to exceed this tolerance on width spacing.
- When mounting chairs over carpet, punch two 5/8″ diameter holes in carpet to match holes in the chair base plate. Bolt leg frames to the floor as per the appropriate anchoring method. Use 1/4″ flat head machine bolts or #14 wood screws and countersink lock washers. Hand-tighten bolts to allow for some slight movement in the leg frame.
- Use the Planar Exploded Assembly drawing as reference for the following instructions and attach back as follows: 1) Place inner upholstered back in front of the back attachment wing brackets, aligning threaded inserts in the back with slots in the wing brackets. Insert (4) 1/4-20 x 5/8″ Allen-drive low-profile machine screws through the slots in the wing brackets and tighten while insuring that the back is centered between the leg frames. 2) Place the outer back panel behind and slightly above the inner panel and slide downwards to engage the flush-mount brackets. Use pinch clamps to draw the bottom of the panels together. Secure the panels by installing (2) 1/4-20 x 1-1/8″ Allen-drive low-profile machine screws through the predrilled holes in the bottom of the inner panel and into threaded inserts in the outer back panel.
- Orient the seat to the approximate occupied position and lower onto seat hinges (C). Install four 1/4-20 x 5/8″ SEMS machine screws through slots in seat brackets and fasten to hinges. Insure seat is centered between legs prior to final tightening.
- Flip seat up and down several times to insure that it pivots and returns to upright position freely. Adjustments can be made to attachment bolts in either the seats or backs.
- Attach armrest by placing the routed area on the underside of the armrest over the mounting plate at the top of the leg frame. Secure using (4) #8 x 5/8″ pan head sheet metal screws.
- Tighten all floor attachments securely.
The Planar chairs are designed and built for years of reliable service. The durability and beauty of the chair will however, be greatly enhanced with proper care and inspection, as described below. Each project will be provided with an Operations and Maintenance (O&M) Manual which will describe in detail the maintenance measures to be taken by onsite personnel.
Inspection and Cleaning
In the first year after the original installation, it is recommended that the chairs be inspected quarterly to insure that all chairs remain secure to the floor, and that the seats and backs remain tight to the leg frames. After the first year, this inspection interval can become longer, but should never exceed 6 months.
There are no components in the Planar chair which require lubrication. Seat pivot hinges include a nylon bushing to insure silent and consistent performance.
Besides inspecting for loose screw attachments, there should not be any routine need for readjustment. If, however, a loose connection is discovered, please refer to the appropriate drawing and instructions for installing the subject component. These drawings and instructions can be found in the O&M Manual.
The Planar chair has been designed and tested to achieve optimum performance and durability. In general, onsite maintenance personnel can provide the appropriate service to correct problems if they have the necessary spare parts and installation instructions.
In the event that a problem with the performance or finish of the chair occurs, it is often possible for immediate on-site remedies. TSI recommends that any loose components should be inspected for any visible evidence of breakage. If evidence is found, the part should be immediately replaced. If there is no evidence of breakage, the attachment hardware should be checked to insure tightness.
Obtaining Replacement Parts
A complete list of spare parts provided with the original installation is included in the O&M Manual. If any additional parts are required, simply contact Theatre Solutions and refer to the appropriate part number or the description listed in a drawing depicting the component.
