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.
A bow tie is the only proper tie to wear with a tuxedo. They come in many shapes, sizes and materials but the most common are the bat wing or butterfly in silk, satin, or velvet. The bat wing is a bit more edgy while the butterfly is classic.
