The biggest commercially available sheets are king size sheets. The standard measurement is 108'; x 102'; for king and 102'; x 110'; for california king.





For what you are looking for, you may need to have something custom made.





As for brand, there is no one real winner - use thread count as a guide to quality. I like 800 thread count sheets - they are soft without being too shiny (like 1000+ thread count). Don't get anything below 300 thread count.What are the biggest size for bed sheets (I mean flat sheets) ? Any quality brand ?
Sheriden make an extra king size that might serve the purpose. Try E bay
