How Much Space a Patio Set Needs
No listing in either group states how much floor space the set takes up once arranged - published item dimensions describe a single seat module or a shipping carton, not the arrangement, so this site does not build a fit check for furniture the way it does for pergolas and the carport.
Checked, not assumed
Every one of the 12 conversation-set and dining-set products in this range was checked for an assembled, arranged footprint - a number describing the set as it sits on a patio, not one piece of it. None publishes one. The Creators API's own itemDimensions field on these listings reads as a single seat module or a shipping carton in every case: the 5-piece sectional set's own itemDimensions, for example, is 26.77 x 25.98 x 25.59 in - too small to be five arranged pieces, and clearly one module or its box instead.
Why this site doesn't estimate it
A rule of thumb ("allow roughly this many square feet per seat") would read as a fact on a page that is otherwise strict about only publishing what the manufacturer states. This catalogue's own dining and conversation sets vary too much in piece shape and arrangement for one estimate to mean anything specific to a given set anyway - a loveseat-and-2-armchair layout and a 7-piece sectional with 3 footstools don't occupy comparable shapes even at similar total piece counts.
What to check instead
Each product's own specifications table states individual piece dimensions where published (a loveseat's own length and width, an armchair's own footprint) - useful for estimating scale, not a substitute for the arranged set. The product photographs on each listing, and the manufacturer's own assembly diagram, are the more reliable way to judge how pieces sit relative to each other before ordering.
Where cushion thickness is published
5 of the 12 products in this range do state a cushion thickness (3 in to 5 in seat, up to 10 in back on one listing) - shown on each of those products' own specifications tables, not summarized in one place, since it's a comfort figure, not a footprint one.
Questions
Does any Wisteria Lane conversation or dining set publish its assembled size?
No - checked across all 12 products in both groups, none publishes an arranged, assembled footprint. Published item dimensions describe a single module or a shipping carton instead.
Why doesn't this site estimate the footprint from piece count?
Because piece count doesn't determine shape or arrangement, and a rule-of-thumb estimate would read as a published fact on a site that otherwise only states what the manufacturer confirms.
Is cushion thickness published?
Yes, on 5 of the 12 products in this range - shown on each of those products' own specifications tables.
