The REP Fitness 3-in-1 Soft Plyo Box is the best plyo box for most home gyms. It gives three heights from one box, has a wood core under a foam cover, and REP lists a 400-pound capacity. The Medium size measures 24 x 20 x 16 inches and weighs 34 pounds.
If floor space is the limit, the REP Adjustable Plyo Box has the smallest base here. If you want the widest range of heights, the Titan Fitness Stackable Soft Foam Plyometric Box Set stacks four boxes. If you want a plain wooden box, CAP’s Wooden Plyometric Box comes in three sizes.
| Plyo box | Best for | Size or base (maker) | Heights | Capacity (maker) |
|---|---|---|---|---|
| REP 3-in-1 Soft Plyo Box, Medium | All-around | 24 x 20 x 16 in; 34 lb | 16, 20, or 24 in by side | 400 lb |
| REP Adjustable Plyo Box | Smallest footprint | 19.8 x 19.8 in base; 40 lb | 16, 20, or 24 in | 400 lb |
| Titan Stackable Soft Foam Set | Widest height range | 28 x 28 in; 74 lb set | Four boxes; 6 to 62 in | 350 lb |
| Search Amazon for the CAP Wooden Plyometric Box, Large | Wooden box | 24 x 20 x 16 in | Not stated by CAP | Not listed |
The CAP link is an Amazon search: the 24 x 20 x 16-inch CAP listing on Amazon shows CAP’s non-slip style and a different model number from the plain wooden box on CAP’s own store, so check the model on any result you open.
Floor space and storage
A 3-in-1 box changes height by turning onto a different side, so its footprint changes with the height you use. An adjustable or stackable box keeps the same base at every height. Using the makers’ figures:
| Plyo box | Base when in use | Largest base area | Stored |
|---|---|---|---|
| REP Adjustable Plyo Box | 19.8 x 19.8 in at every height | 2.7 sq ft | One box |
| REP 3-in-1 Soft, Medium | 24 x 20, 24 x 16, or 20 x 16 in, by side | 3.3 sq ft | One box |
| CAP Wooden, Large | Largest side 24 x 20 in | 3.3 sq ft | One box |
| Titan Stackable Set | 28 x 28 in (set) | 5.4 sq ft | Four boxes, 62 in tall stacked |
The REP Adjustable needs the least floor, about 2.7 square feet. Titan’s set needs the most, about 5.4 square feet, and stands 62 inches tall when all four boxes are stacked for storage.
1. REP Fitness 3-in-1 Soft Plyo Box: best all-around plyo box
REP lists the 3-in-1 Soft Plyo Box in three sizes: Small at 20 x 18 x 16 inches and 27 pounds, Medium at 24 x 20 x 16 inches and 34 pounds, and Large at 30 x 24 x 20 inches and 58 pounds, all rated for 400 pounds. Each has an inner wood core covered in soft foam, the height is marked on each side, and it comes fully assembled. REP says the wood core keeps the box stable on all sides and the foam cover absorbs impact.
Why it wins. One box gives three heights with a wood core under foam, and REP lists the highest capacity here, matched only by its own Adjustable box.
The real compromise. Its footprint changes with the height you choose, and the Large size weighs 58 pounds. The link goes to the Medium (24-inch) listing; REP sells the Small and Large as separate Amazon listings.
Buy it if you want one box that covers three heights. Skip it if you need heights below 16 inches or above 24 inches in the Medium.
2. REP Fitness Adjustable Plyo Box: best for the smallest footprint
REP lists the Adjustable Plyo Box with a 19.8 x 19.8-inch base, a 16 x 16-inch landing area, and three heights of 16, 20, or 24 inches that REP says take about 30 seconds to switch. The box weighs 40 pounds, is rated for 400 pounds, and ships assembled. It has a rubber top, rubber feet, and twist-lock handles.
Why it wins for its buyer. It has the smallest base here, and that base stays the same at all three heights.
The real compromise. Its 16 x 16-inch landing area is the smallest top here, and changing height means adjusting the box rather than turning it over.
Buy it if the box has to fit a small corner. Skip it if you want a soft surface or heights outside 16 to 24 inches.
3. Titan Fitness Stackable Soft Foam Plyometric Box Set: best for the widest height range
Titan’s set has four soft boxes, which Titan says give over 20 height combinations from 6 to 62 inches. Titan lists the set at 28 x 28 inches and 62 inches tall when stacked. The boxes have a high-density EPE foam core, a slip-free surface, Velcro flaps and strips for stacking, built-in handles, and height indicators. Titan lists a 350-pound capacity, a 74-pound set weight, and no assembly. Titan says to land jumps on the center of the landing surface.
Why it wins for its buyer. It covers the widest range of heights here, from a 6-inch step to a 62-inch stack.
The real compromise. Its 28 x 28-inch footprint is the largest here, and the full stack is 62 inches tall in storage. Its 350-pound capacity is lower than REP’s.
Buy it if you want low and high heights from one set. Skip it if floor space is tight or you need more than a 350-pound capacity.
4. CAP Wooden Plyometric Box: best wooden plyo box
CAP sells its Wooden Plyometric Box in three sizes: Large at 24 x 20 x 16 inches, Medium at 20 x 18 x 16 inches, and Small at 16 x 14 x 12 inches. CAP lists wide handles for carrying, an interlocking connection design, countersunk screws, and smooth-finished edges.
Why it wins for its buyer. It is the only all-wood box here, and its Large size has the same outer dimensions as REP’s Medium soft box.
The real compromise. CAP’s product page does not list a weight capacity or box weight, so you cannot compare it with the others on those points. A wood box has hard edges where the soft boxes have foam.
Buy it if you want a plain wooden box in a common size. Skip it if you want a published capacity or a soft surface.
How to choose a plyo box
- Measure the floor. Bases here run from 19.8 x 19.8 inches (REP Adjustable) to 28 x 28 inches (Titan), and a 3-in-1 box’s footprint changes with the side it sits on.
- List the heights you need. REP’s Medium 3-in-1 and its Adjustable cover 16 to 24 inches; Titan’s set runs from 6 to 62 inches.
- Check the capacity. REP lists 400 pounds for both of its boxes and Titan 350 pounds; CAP does not list one.
- Choose the surface. The REP 3-in-1 is foam over a wood core and Titan’s boxes are foam-cored; the REP Adjustable has a rubber top, and CAP’s box is wood.
- Check the floor surface. REP says not to use plyo boxes on smooth or slippery surfaces, and Titan says its set is not recommended for slick floors. The garage gym flooring guide covers rubber floor options.
