The Tower-90 is a modular, tool-free hardwood bookshelf from Perfect BookShelf that you can expand and reconfigure over time. At 90″ tall, 90″ wide, and 10″ deep, it's the widest vertical unit in the collection — a near-square, wall-spanning system that turns a full wall into floor-to-near-ceiling storage while staying just 10″ deep. Use it as a complete wall of shelving on its own, or as the anchor of an even larger modular layout, adding or rearranging sections as your collection grows. Built from solid hardwood and plywood with a natural, visible-grain finish, it brings a warm, modern look to living rooms, home offices, and bedrooms, and assembles with no tools required. Highlights Modular and expandable — add shelves or reconfigure sections over time; use it alone or build it into an even larger modular wall system Widest vertical storage — 90″ wide and 90″ tall creates a full wall of shelving in a slim 10″-deep footprint, the most vertical capacity in the line Fits standard ceilings — at 90″ (7'6″) tall, it clears a standard 8-foot ceiling, unlike taller units in the range Tool-free assembly — sets up with no tools or hardware, so it's easier to build and adapt than a comparable built-in unit Solid hardwood and plywood construction — durable and built to hold up to 55lbs Natural visible-grain finish in three options: Maple, White Oak, and Walnut Includes wall-anchoring hardware for safe, stable installation Specifications Dimensions: 90″ W × 10″ D × 90″ H Orientation: Vertical (widest, near-square) Materials: Solid hardwood frame with plywood panels Finish: Natural, visible grain — available in Maple, White Oak, or Walnut Assembly: Tool-free, no hardware required for assembly; wall anchor included Minimum ceiling height: 90″ (7'6″) — fits a standard 8-ft ceiling Weight capacity: 60lbs per shelf and 420lbs total Number of shelves: 7 Wall-anchoring: Required for safety Price: starting at $3,385.00 Frequently asked Will the Tower-90 fit a standard 8-foot ceiling? Yes — at 90″ (7'6″) tall, it clears a standard 8-ft ceiling with room to spare. Can I add to this bookshelf over time? Yes — the Tower-90 is modular, so you can add or reconfigure sections as your collection grows. How is it different from the other Towers? All are tall vertical units; the 50 is 50″ wide, the 70 is 70″ wide, the 80 is 80″, and the 90 is the widest at 90″. Choose by wall width and storage needs — and check each unit's height against your ceiling. Does a unit this wide and tall need to be anchored to the wall? Yes — it must be anchored for stability, and the anchoring hardware is included. Does it need tools to assemble? No — it assembles without any tools or hardware.
