Open the CIPO recordAbstract From the Canadian patent
An article of furniture made of a quasi-rigid foam material. The furniture includes a base for sitting thereon. A back support member is wrapped around the base such that a portion of the support member extends upwardly with respect to the base. The support member has a pair of ends that wrap around at least half of a cylindrical surface of the base to translate a force from an upwardly extending portion of the support member to the ends and prevent tearing of the support member from the base.

Why it's free to use
- Filed September 20, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 20, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 20, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
