Most plush mattresses have a solid inner core of coils. Plush and pillow top spring mattresses are similar; both typically have structural firmness and stability. They also have a soft outer fabric surface intended to make sleep more comfortable.
A necktie, or simply tie, is a long piece of cloth worn for decorative purposes around the neck, resting under the shirt collar and knotted at the throat. Variants include the ascot tie, bow tie, bolo tie, zipper tie, cravat and clip-on tie. The modern necktie, ascot, and bow tie are descended from the cravat.
Size, symmetry and shape can vary greatly from knot to knot and all should be taken into consideration. Thick ties often necessitate the use of smaller knots like the Four-in-Hand or the Simple knot. Thin ties generally benefit from larger knots like the Pratt or Windsor. Every knot has a distinct character.
