Round or elongated, measured on the bowl you already own · review
Delta's plastic elongated seat with slow close and non-slip bumpers, described as solid for added weight — six short bullets, and the highest price of the four.
That is the whole page: slow close, bumpers, fit, fixing, solidity, material. The spec table adds 18.5 × 14 inches, 4.2 pounds and a 1-year limited warranty.
At about $37, this is the most expensive seat on this shelf. The KOHLER Brevia, about $5 less, adds quick-release hinges and a compact elongated fit; the Mayfair wood seat, about $2 less, adds stay-tight hinges and weight.
Available at around $36.99 on Amazon.com when we checked on October 29, 2026, for delivery to a US address.

Both are plastic, slow-close elongated seats with bumpers against sliding and about 4.2 pounds. The KOHLER states quick-release hinges and a fit for compact elongated bowls, and costs about $5 less. Delta states solid construction and a fixing against loosening.
A plastic seat molded without a hollow underside, which makes it heavier and stiffer. Delta presents the weight as strength; the page gives 4.2 pounds.
It is stated to fit most elongated bowls, at 18.5 by 14 inches. Measure from the bolt holes to the front edge: about 18.5 inches is elongated.
Same category, nearby prices, between bathroom fittings. What remains is the specifications every one publishes — half empty, a column is no use.
