Before ordering dining tables, assign a representative set of parties to each proposed mix. Two furniture lists can contain the same number of seating places while accommodating different groups at the same moment. An unused chair at an occupied table is not automatically available to another party.
Use this check after establishing which complete table-and-chair configurations suit your service. It compares quantities and assignments; the room plan still needs the actual dimensions, circulation and applicable project review.
Collect parties that overlap in time
For an operating restaurant, choose service periods that matter to the purchase: perhaps a busy dinner, a weekday lunch and a recurring group booking. Record the parties actually seated at a common point in each period, with their sizes and table assignments. Add known placement problems rather than relying only on the total guest count.
A whole shift's covers do not describe simultaneous demand. A table used for an early party and then a later party is one table used twice. Combining both parties in the same snapshot would inflate the required furniture.
For an opening, use confirmed bookings where available and clearly named scenarios for the remaining demand. Keep an assumption about eight couples separate from an observed service record. Do not choose a supposedly typical party-size percentage without evidence for your restaurant.
Compare equal seat totals by actual assignment
The following example is invented. It assumes two table types have already been accepted for their stated use: a two-place table and a four-place table, each with its corresponding loose chairs. It assumes each party has its own table, with no communal sharing, splitting parties or joining tables in this first check.
| Proposed mix | Two-place tables | Four-place tables | Total tables | Listed seating places |
|---|---|---|---|---|
| A | 6 | 4 | 10 | 28 |
| B | 2 | 6 | 8 | 28 |
Mix A has (6 × 2) + (4 × 4) = 28 places. Mix B has (2 × 2) + (6 × 4) = 28 places too.
Now consider eight parties of two and one party of four, all seated concurrently: 20 diners in nine parties.
- Mix A: seat six pairs at the six two-place tables. Two more pairs use two four-place tables, and the four-person party uses a third four-place table. One four-place table remains unassigned. All nine parties have a table.
- Mix B: the two two-place tables and six four-place tables provide only eight separate tables. If all eight pairs are seated first, every table is occupied and the four-person party has no table. Seating that party first leaves one pair without a separate table instead.
The result does not make Mix A universally preferable. It shows why 28 listed places alone cannot decide this particular demand scenario. Neither list establishes that ten or eight tables will fit the premises.
Test another service before choosing the order
Repeat the assignment with a different relevant set of parties. Use table identifiers so each physical unit is allocated once. Mark any party that cannot be placed under the proposed rules, along with the reason.
Record constraints that make nominally empty tables unavailable: a closed section, a table awaiting reset, a reservation being held or a configuration unsuitable for the intended guests. Do not silently count those tables as usable inventory.
If a comparison depends on a turnover assumption, test the overlap around it. A forecast that frees a table just before another party arrives should also show what happens if the earlier party is still there. Use your own observed timing or label the scenario as uncertain.
Count a joined setting only after it works
Tables that are intended to combine can change the result, but they are not free extra tables. Joining two units for one party removes both units from the separate-table inventory until they are available again.
Name each usable combination and test the actual top heights, edges, bases, chair positions and arrangement. Confirm the selected product's joining requirements with the supplier and review the combined setting on the room plan. Similar-looking tops do not prove a usable combined configuration.
Restaurant software also needs to reflect the physical choices. OpenTable's own table-management description includes custom floor plans, table inventory and covers reports. If you use a reservation system, make its available configurations match the combinations you have actually approved. A setting entered in software cannot make an unsuitable furniture arrangement work.
Turn the selected mix into identifiable purchase lines
Once the comparison and room review are resolved, list quantities by the exact approved table type. Record complete assemblies or separate compatible tops and bases consistently. Keep retained suitable tables and any deliberately chosen spares visible rather than adding an unexplained extra percentage.
Count chairs from the chosen physical arrangements, separately from the number of diners in a demand snapshot. In the invented example, a decision to furnish every listed place would require 28 loose chairs under either mix. The 20 diners in that one snapshot are not the complete chair order.
Carry the selected mix into the opening furniture checklist. Send the quantities, dimensions, tested combinations and location through the furniture inquiry when asking about sourcing. Ask for product-specific support and availability; the assignment exercise explains the requested mix without promising a sales increase or approving the room's capacity.
