The best soft-close toilet seat for your bathroom is the one that fits your bowl and offers the conveniences you’ll actually use. First check whether your toilet is round-front or elongated; then compare the seat’s listed dimensions, closing hinge, cleaning access, fastening features and material. The Bemis Affinity, Bemis 7300SLEC and KOHLER Zofa are manufacturer-documented options, not independently tested or ranked products.
Start with bowl shape and fit
Before shopping, identify whether your toilet is round-front or elongated. A seat made for one shape is not automatically suitable for the other. The cited KOHLER Zofa K-4764 is round-front; Bemis lists Affinity models in both round and elongated shapes. The Bemis 7300SLEC page says it fits most manufacturers’ toilets, but “most” does not mean every toilet.
Compare your bowl and mounting points with the specific model’s dimensions and fit instructions before ordering. Bemis publishes bolt spread and exterior measurements for the two seats below. KOHLER’s cited Zofa page confirms its shape but does not provide dimensions in the captured product information, so check the current model specifications before purchase.
Compare documented soft-close options
Each product feature below comes from its manufacturer’s product information. Soft-close describes a hinge intended to lower the seat and cover slowly and quietly; these descriptions are not independent sound, comfort or durability test results.

For more adjustment and movement-control features: Bemis Affinity
The Affinity combines soft closing and removable hinges with documented front-to-back adjustment, Stay·Tite fastening and Super·Grip bumpers.

For soft closing and easier cleaning: Bemis 7300SLEC
The 7300SLEC is a simpler feature match if your priorities are a soft-close hinge and removable hinges for cleaning. Its cited page does not specify the bowl shape, so do not assume compatibility from the “fits most” statement alone; confirm shape and fit with the seller or current model specifications.
For a foam seat: KOHLER Zofa K-4764
KOHLER describes the Zofa as a round-front soft comfort quiet-close seat with closed-cell foam and a contoured design. The warmer-to-initial-touch description is KOHLER’s product positioning, not an independent comparison. Consider it only if your bowl is round-front and the model’s fit details match your toilet.

Soft-close and quick removal are separate features
A seat can have quick-release or removable hardware without being documented as soft-close. For example, KOHLER describes its round-front Brevia K-4775 as a plastic contoured seat with quick-release and quick-attach hardware, but the cited product page does not identify it as soft-close. Treat that model as an example of the distinction, not as a soft-close recommendation.
