Research note: This buying guide uses current Knoll product information and dimension documents. It is not a Furniblog hands-on test, comfort guarantee or authentication service.
Womb Chair in one minute
The Womb Chair is fixed lounge seating designed by Eero Saarinen for Knoll, not an adjustable desk chair. Its purchase case is the enveloping shell, recognizable design and choice of upholstery. Buyers needing seat-height, lumbar, arm or recline adjustments should compare task chairs instead.
Standard and medium dimensions
Knoll lists the standard 70L chair at 40 inches wide, 34 inches deep and 35.5 inches high, with a 16-inch seat height. The 70LM medium is listed at 35 inches wide, 31 inches deep and 31.25 inches high, with a 15-inch seat height. Use the current regional specification for the item being ordered.
| Version | Width | Depth | Height | Seat height |
|---|---|---|---|---|
| Standard 70L | 40 in | 34 in | 35.5 in | 16 in |
| Medium 70LM | 35 in | 31 in | 31.25 in | 15 in |
Configuration and room-fit checks
Choose the chair size, upholstery and base finish from the actual seller configuration. Measure the full footprint and circulation space rather than comparing seat width alone. If adding an ottoman, use the matching size shown in the Knoll dimension sheet and include that footprint in the room plan.
What the standard store listing establishes
The current Knoll US standard-chair listing identifies the product as fully assembled and publishes dimensions, product weight, capacity and a five-year warranty subject to terms. Those details apply to that listing and date; do not transfer them automatically to vintage, used, medium-size or marketplace offers.
Authenticity, condition and seller
A product title, silhouette or high price is not proof of an authentic Knoll chair. For a new purchase, verify the manufacturer and seller through Knoll's channels. For a used chair, request provenance, labels, detailed photographs, repair history and upholstery information. Furniblog does not authenticate furniture.
Using the Amazon search link
The Amazon button intentionally opens search results because a stable, exact Knoll offer is not confirmed. Results can include replicas, similar chairs, covers, ottomans or used items. Check manufacturer, contents, size, condition, seller, delivery and returns before checkout.
Womb Chair vs Barcelona Chair
Both are fixed lounge designs rather than task chairs, but they differ in shape, dimensions and configuration choices. Compare the Womb Chair and Barcelona Chair, or read the Barcelona Chair buying guide for its frame, cushion and provenance checks.
Bottom line
Shortlist the Womb Chair for a lounge setting only after confirming size, finish, seller and provenance. Do not buy it as a substitute for an adjustable office chair, and do not use a marketplace result as evidence that the item is an authentic Knoll product.
