Note 12 - Commitments and Contingencies (Details) [Line Items]
Description of Lessor Leasing Arrangements, Operating Leases				The Company subleased a portion of its warehouse space to one of its customers with a one-year term commencing on December 1, 2013 and expiring on November 30, 2014, which has been renewed every year with the current term expiring on October 31, 2018.

Loss Contingency, Allegations	On December 28, 2018, a Federal class action complaint was filed by George Barney against the Company and its former and current CEOs and CFOs (Thanh H. Lam, Ya Ming Wong, Jeffery Chuang and Yuen Ching Ho) in the United States District Court for the Central District of California, claiming the Company violated federal securities laws and pursuing remedies under Sections 10(b) and 20(a) of the Security Exchange Act of 1934 and Rule 10b-5 (the “Complaint”). The Complaint seeks to recover compensatory damages caused by the Company’s alleged violations of federal security laws during the period from December 3, 2015 through December 20, 2018. In reliance solely on a blog appearing in Seeking Alpha on December 21, 2018, the Complaint states that the Company made false and/or misleading statements and/or failed to disclose that: (1) the Company overstated its purported strategic alliance with a customer in China to operate as lead designer and manufacturer for all furnishings in such customer’s planned $460 million senior care center in China; (2) the Company inflated its reported sales in 2016 and 2017 with the Company’s two major customers; and (3) as a result, the Company’s public statements were materially false and misleading at all relevant times. The Audit Committee engaged the Company’s auditor to perform special procedures to confirm the reported sales. Those procedures included but were not limited to the examination and testing of relevant documentation relating to the sales made by the Company to the customers identified in the purported research report for the periods 2015-2018, and 100% sampling of all transactions between the Company and the subject customers. The Audit Committee finished its special procedures in March 2019 and the Company’s independent auditor has reported to the Audit Committee that, regarding the four subject customers mentioned in the purported research report, the special procedures resulted in no evidence of fictitious sales or of fictitious customers.
