SONGMICS Stackable Expandable Cabinet Shelf (Set of 2) Review (2026)

What it is

This set includes two cabinet riser shelves at two closely related sizes, a large one measuring about 11.7 by 7.6 by 6.1 inches and a small one at about 11.7 by 7.3 by 5.4 inches, built with an iron frame and bamboo or engineered wood top surface depending on the color option. Because the two shelves are slightly different sizes, they can nest inside each other for compact storage when not needed, or pull apart and be positioned side by side to expand coverage across a wider cabinet or countertop. Each shelf weighs about 2.8 pounds and the set ships with an accessory bag and instructions for the light assembly involved.

Fit for the job

The nesting and expanding design is the standout feature for small kitchens, since a single fixed-size riser often either wastes space in a narrow cabinet or leaves gaps in a wide one, while this set's two slightly different heights let it adapt to either situation, or stack both risers for a taller three-tier arrangement. The metal frame construction is sturdier than plastic risers common at this price point, and each shelf is rated to hold up to 33 pounds statically, enough for stacks of plates, canned goods, or other everyday kitchen items rather than just lightweight spice jars. That combination of adaptability and real weight capacity is what makes it useful beyond a single fixed cabinet.

Assembly and installation

Unlike some risers that arrive fully formed, this set requires light screw assembly to attach the frame legs to the top surface, which is a step worth knowing about before purchase since it is not a fully tool-free, out-of-the-box product the way some plastic stacking risers are. The assembly itself is simple, following printed instructions and using the included hardware, and most buyers should be able to complete both risers in a short amount of time without power tools. Once assembled, the risers do not fold flat, so they need enough vertical clearance in the cabinet to store when not in active use.

Fit inside cabinets

Because the two risers have a fixed footprint once assembled, a cabinet that is shallower than the standard 11.7 inch length of these shelves will see the riser overhang the front edge, which is worth checking before buying if cabinet depth is already tight. On a standard-depth kitchen cabinet, though, the fit works well, and the nesting design means the smaller riser can sit inside the larger one for compact storage in a cabinet that has less need for expanded coverage on a given day. Versatility across cabinets, countertops, and pantry shelves is a genuine strength, since the set is not limited to just one location in the kitchen.

Who should buy it

This set suits a tiny-kitchen renter who wants to add real vertical storage inside cabinets without committing to a single fixed-size riser, and who does not mind a short screw assembly step in exchange for a sturdier metal-and-wood build than plastic alternatives. It is a weaker fit for anyone with unusually shallow cabinets that cannot accommodate the roughly 11.7 inch footprint, or for buyers who specifically want a fully tool-free product straight out of the box. For most standard-depth kitchen cabinets and pantries, the trade-off of a few minutes of screw assembly for a sturdier, higher-capacity riser than an all-plastic option is a reasonable one.
