Introduction | Similar at first glance, very different in
daily use
Kartell’s Componibili and B—Line’s Boby
trolley both use rounded plastic forms and the playful spirit of Italian design
from the late 1960s and early 1970s. In photographs they can look like close
alternatives, but they solve different problems. Componibili behaves like a
compact stationary cabinet and side table. Boby is a mobile organizing system
designed to separate tools and move them to the place where the work happens.
For a bedside, living-room corner or dry
bathroom area where visual calm matters, Componibili is usually the easier fit.
For stationery, cosmetics, craft supplies or children’s art materials that need
to be sorted and moved, Boby is generally more capable. Both are recognized
design icons, but the best choice depends less on fame than on what you store
and how often you reach for it.

1. Introducing the Kartell Componibili
Componibili is a cylindrical storage system
created by architect and designer Anna Castelli Ferrieri for Kartell. Kartell
dates its first appearance to 1967. Today’s Classic line has a 32 cm diameter
and is sold in fixed two-, three- and four-element configurations. Each door
slides sideways along the curved body and uses a circular opening as its
handle.
Its strength is the way storage can sit in
a room without looking heavy. The rounded body softens a tight circulation
path, while the shallow rim on top is useful for glasses, a phone or a cup.
Close the doors and everyday clutter disappears, which is especially valuable
in a bedroom or living room.

2. Where Componibili works well
·
Bedroom: use the two-tier
version as a low bedside table or the three-tier version when more storage is
needed.
·
Living room: place it beside a
sofa and hide remotes, chargers and tissues.
·
Children’s room: separate small
toys or art supplies by level, while keeping the unit on a flat floor and
preventing climbing.
·
Vanity or dry bathroom zone:
organize towels, paper goods, a hair dryer or skincare, while controlling
moisture and allowing ventilation.

3. Componibili: advantages and limitations
Advantages
·
A 32 cm diameter makes it easy
to place in a small bedroom or studio.
·
Closed doors conceal the
contents and create a tidy visual impression.
·
The rounded form and color
options allow it to work as storage, side table and accent piece.
·
The simple exterior is
relatively easy to wipe clean.
Limitations
·
The cylindrical interior is
inefficient for large books, documents and square organizers.
·
The current Classic line has no
casters, so it is not intended to move frequently when loaded.
·
Current two-, three- and
four-tier Classic units are fixed structures and cannot be separated or
reconfigured after purchase.
·
Fine scratches and dust may
show on glossy plastic, so a soft cloth is safer than abrasive cleaning tools.

4. Introducing the B—Line Boby trolley
Boby is a mobile storage trolley designed
by Joe Colombo in 1970. B—Line describes injection-molded ABS drawers and
compartments arranged in vertical modular configurations, supported by
polypropylene casters. Its 430 × 420 mm footprint is offered in heights of 315,
525, 735 and 945 mm, allowing users to choose a working height and storage
capacity.
Unlike a conventional drawer cabinet that
opens in one direction, Boby combines rotating drawers, open shelves, side
compartments and a divided top tray. It therefore behaves more like a compact
mobile workstation. The Museum of Modern Art describes Boby 3 as an all-in-one
organization system on wheels with shelves, bins and trays, highlighting its
early vision of multifunctional, customizable furniture.

5. Where the Boby trolley works well
·
Home office: divide pens,
cables, notes, drives and desk accessories by function.
·
Vanity: keep short bottles in
rotating drawers and frequently used brushes in the top tray.
·
Craft room: collect sewing
tools, scissors, tape, brushes and paint in one mobile station.
·
Children’s art area: separate
pencils, paper and making materials, with adult supervision around the wheeled
unit.

6. Boby trolley: advantages and limitations
Advantages
·
Casters let you move a complete
set of supplies for cleaning or changing work areas.
·
Rotating drawers, open storage
and a top tray support detailed organization of small objects.
·
Multi-directional access allows
use away from the wall and in the center of a work zone.
·
Several heights and drawer
combinations suit both professional studios and homes.
Limitations
·
At 43 × 42 cm, it takes more
floor space than Componibili and may feel large beside a narrow bed.
·
Placing it too close to a wall
or cabinet can block access to some drawers and shelves.
·
Open shelves and the top tray
provide fast access but collect dust and expose visual clutter.
·
Because configurations vary,
buyers must check the exact model and drawer count; the system may be excessive
if a simple bedside table is all that is needed.

8. Which one should you choose?
Choose Componibili when you want a compact bedside
surface for a glass, phone and glasses, with tissues or chargers hidden inside.
It also works well beside a sofa or anywhere that needs a small, visually calm
accent cabinet.
Choose Boby when cables and stationery
gather around a desk, or when cosmetics, nail tools, sewing supplies and other
differently sized objects must be found quickly. The more important it is to
organize by workflow and move everything together, the more valuable Boby
becomes.
Before buying, mark the footprint on the
floor with masking tape: a 32 cm circle for Componibili and a 43 × 42 cm
rectangle for Boby. Check the walkway and the clearance needed to open the
storage. Boby needs particular attention because access from several sides is
part of its usefulness.
FAQ
Q. Can casters be added to Componibili?
A. Kartell describes the current
Componibili Classic as a fixed unit for direct floor placement and states that
casters cannot be fitted to this line.
Q. Can I separate or add tiers later?
A. Current official Classic two-, three-
and four-tier products are fixed structures, not separable modules. Do not
assume that features of vintage or earlier versions apply.
Q. Can Boby work as a bedside table?
A. Yes, but allow for its 43 × 42 cm
footprint, casters and multi-directional storage. For a simpler, smaller
bedside role, Componibili may feel neater.
Q. Which is better for children’s storage?
A. Boby suits frequently moved art
materials; Componibili is better when the goal is to hide toys. Prevent
climbing or hanging and use either unit on a level floor.
Q. Are they suitable for bathrooms?
A. They can work in a dry bathroom zone,
but avoid standing water and poorly ventilated interiors. Follow the
manufacturer’s care guidance and use a soft cloth with gentle cleaning methods.
Conclusion
Componibili is strongest when compact size,
concealed storage and side-table function matter. Boby is strongest when
mobility, detailed organization and rapid access to work tools matter. Both
have substantial design pedigree, but the decision is practical: choose
Componibili to keep one spot calm and tidy; choose Boby to divide supplies and
move them wherever they are needed.
