Steinway designed Boston pianos are one of the finest pianos in the World today. This 5'4" Boston grand piano was purchased new in 1995 by a family in Chicago's suburb and only lightly used. The hammers have only the slightlest wear and the piano has no damage.

This Steinway Boston 5'4" grand is the perfect size for almost any home, but producces the tonal range of a larger grand. This is due to the much wider back tale allowing Steinway to use a larger soundboard.

This is a unbelievable piano in new condition for a fraction of new. Call 708-516-2506



Rim/Backframe Laminated hard rock maple (Acer Saccharum) inner rim. Laminated Philippine mahogany outer rim. Continuous bent rim. 11 outer rim laminations, 17 inner rim laminations. 23mm (7/8”) outer rim width, 38mm (1 ½”) inner rim width.
Braces/Posts Radiating braces of laminated Philippine mahogany provide stronger triangular support than parallel designs. This rigid support increases tuning stability, soundboard, crown retention, and longer piano life. 3 braces.
Pinblock Octagrip™ pinblock made of 11 layers of hard rock maple – glued in different grain angles of 60 degrees – affording the tuning pins greater stability under tension and enabling the piano to stay in tune longer.
Soundboard Close and straight-grain solid (not laminated) Sitka spruce. Minimum 3 annual growth rings per cm (minimum 8 per inch). Tapered from treble to bass, which allows a greater freedom of movement thereby creating a richer and more lasting tonal response. Tapered from 8 mm to 6 mm. Vibrating area: 1.15 m2 (1,776 in2)
Ribs Made from durable spruce to assure strong and constant support of the strings bearing down on the soundboard. Ribs are fully let-in to the inner rim to support the important soundboard crown and prevent the piano from losing its tone. Number of ribs: 10
Bridges Treble: Vertically laminated (alternating maple and mahogany) with a solid maple cap, curved to fit the crown of the soundboard. Bass: Solid maple mounted to cantilevered base.
Scale Overstrung: combination agraffe; with front and rear duplex. Lower tension scale for longer sustaining tone and longer life of the whole piano. 17,251 kg (38,032 lb) tension.
Plate Cast from grey iron, bronze-painted and lacquered. Vacuum cast.
Tuning Pins Nickel-plated steel, cut threaded.
Strings Treble: Highest grade steel (in half size increments). Number of sizes: 13. Lowest tenor note: 27. Mapes Bass Strings: Steel core wire wound with solid copper. Made by Mapes in Tennessee, U.S.A. Number 1 speaking length: 119.4 cm (47”)
Hammers Premium wool topfelt over premium wool underfelt. Weight of topfelt: 9.5 kg (20.9 lb). Compression-wired to retain permanent shape. Mahogany moldings. Tapered hammer-shanks from select resilient maple or horn-beam. Computer-designed pear-shaped hammers with reinforced shoulders result in superior tone, increased durability and greater voicing ability.
Action Solid maple (all wood, no plastic) for all moving parts. Steinway profile-shaped flanges, extruded aluminum action rails for increased stability and less frequent regulation. Steinway action geometry provides superior touch.
Keys Genuine spruce, individually balanced and weighted. Synthetic ivory and ebony key covers. New synthetic ebony has ebony-like surface texture and appearance that absorbs perspiration from the fingers. The fine synthetic ivory of the white keys has the same properties of friction, porosity, conductivity, and appearance as ivory.
Keybed Made from laminated hardwood faced with spruce. Strong, rugged construction provides a solid mount for the keyframe and action allowing for precise and prolonged action regulation. Large maple dowel ends provide a solid mount for adjustable brass touch-regulating glides. Keybed thickness is 42 mm.
Keyframe Spruce with hardwood inserts in the balance rail and front rail for added stability.
Pedals Heavy solid brass castings. Soft, full sostenuto and damper (sustaining).
Other Music desk positions: 4 Fallboard: Soft fall fallboard Casters: Heavy-duty double-wheel solid brass casters. Locks: Fallboard and top locks. PropSticks: Double top prop sticks.
