精度 — precision

What does the name SEIDO mean?

SEIDO Cookware takes its name from 精度 (seido), the Japanese word for precision. It is a fact about the name — a standard the brand holds itself to: exact sizes, one honest surface and nothing hidden under a coating.

Performance

Built to sear.

Uncoated stainless steel takes the hob heat that real searing demands and builds the browned fond that makes pan sauces work. The technique is simple to learn.

Frequently asked questions

Is stainless steel cookware safe?

SEIDO Cookware frying pans are tri-ply clad, with a 304 (18/8) stainless steel cooking surface. The frying pans and the lunch boxes are made without intentionally added PFAS and without synthetic coatings. Because the pans are uncoated, the cooking surface is the steel itself — there is no synthetic layer to scratch, flake or wear away over years of use.

Do SEIDO Cookware frying pans have a non-stick coating?

No. SEIDO Cookware frying pans are uncoated by design. The cooking surface is 304 (18/8) stainless steel with no synthetic coating applied — no coating to flake, wear thin or fail after hard use. Uncoated stainless steel takes high heat on the hob, sears properly and scrubs back to clean metal. Food release comes from technique — preheating and fat — which our guides explain step by step.

Where can I buy SEIDO Cookware in the UK?

SEIDO Cookware is sold in the UK on Amazon.co.uk. This site is the brand's education and product-information home: read the guides, compare the three frying pan sizes, then follow the 'See price on Amazon' link on any product page. The frying pans, the stainless steel lunch box 3-pack and the kitchen tools are all sold on Amazon.co.uk.

What warranty does SEIDO Cookware offer?

Every SEIDO Cookware product on this site is covered by a 5-Year Limited Warranty. That includes the uncoated stainless steel frying pans in all three sizes — 20 cm (8 in), 24 cm (9.5 in) and 28 cm (11 in) — the stainless steel lunch box 3-pack, and the chef's knife, honing steel and serrated peeler. Because the pans carry no synthetic coating, there is no surface layer whose failure cuts the pan's working life short.
