Plyobox: the Sidea selection
The plyobox is an essential piece of equipment for anyone working on explosive power. Designed for exercises such as box jumps, depth jumps, step-ups and Bulgarian split squats, it allows you to challenge the neuromuscular system with controlled intensity. The Sidea range includes plyometric boxes made from plywood, low-impact soft foam boxes, interchangeable covers and linings, combination kits and accessories such as the Split Squat Roller. All feature a 3-in-1 design: three working heights are available simply by rotating the equipment, without the need to purchase additional pieces. A simple, versatile design, suitable for both individual sessions and group circuit training.
Who is Plyobox for?
The plyo box is used in a much wider range of contexts than you might think. In CrossFit boxes, it’s practically indispensable: box jumps feature in almost every WOD that involves componentin terms of power, and the wooden version is the de facto standard. Strength and conditioning coaches use it systematically in strength-building programmes for team sports, athletics and combat sports: the working height varies according to the athlete’s level and the objective, ranging from 30 cm for reactive training up to 75 cm for advanced athletes. Personal trainers find the soft foam version offers a real advantage: the risk of shin injuries if a jump is missed is virtually eliminated, making the equipment more suitable for intermediate clients or those still learning the movement. For home gyms and garage gyms, the 3-in-1 box solves the problem of space: three heights, a single footprint. The same applies to schools and sports centres, where the equipment’s versatility justifies the purchase even on a tight budget.
How to choose
The first distinguishing factor is the material. The wooden plyobox — available in the 9111 and 9111V versions — is made from plywood with non-slip surfaces. It is the standard choice for those seeking rigidity, durability and a feeling of stability underfoot that foam cannot replicate. The well-known drawback is the sharp edges: misjudging the height during a jump can easily lead to bruising on the shins. This is why the soft plyobox (9112V and 9116 Foam Plyobox) exists: the foam covering absorbs the impact and drastically reduces the risk of injuries caused by a misjudged jump. It is preferable in settings where there are many users, mixed ability levels, or simply when safety takes precedence over the feel of a rigid surface.
The 3-in-1 design is a key feature: by rotating the unit, you can achieve three different working heights — typically 50/60/75 cm in the standard versions — which eliminates the need for multiple separate units. If you’re planning intensive use with many athletes training simultaneously, it makes sense to purchase several units rather than just one. The covers and liners (9112R and R9105–R9107) allow you to convert a wooden plyobox into a soft-impact version or to renew a worn surface without replacing the entire box.
Anyone wishing to expand their training beyond the box jump can incorporate the Split Squat Roller (available in Stand and Peg versions), which transforms the box into a station for Bulgarian split squats with movement assistance. For those starting from scratch or looking to quickly set up a functional training space, themed kits such as the Plyo Kit (9111K), the Metcon Kit (2090K) or the Functional Home Kit (9024K) combine the plyobox with other complementary equipment in a single solution.

The wooden plyobox provides a rigid and stable surface, favoured in competitive settings and by experienced athletes. The soft plyobox reduces the risk of bruising if the height is misjudged during a jump, and is more suitable for intermediate users, work with mixed-ability groups or environments where safety takes priority over the feel of a rigid surface.
-
A 3-in-1 plyobox offers three different working heights in a single piece of equipment: by rotating the box onto one of its three sides, you can change the jump height. In the standard Sidea versions, the typical heights are 50, 60 and 75 cm. This eliminates the need to buy three separate boxes and reduces the space taken up in the gym or home gym.
-
The choice of height depends on your fitness level and your goal. For those just starting out or working on their box jump technique, 40–50 cm is a suitable starting point. Heights of between 60 and 75 cm are reserved for athletes with good control of the movement and who have already developed a good level of explosive strength. For depth jumps and reactive exercises, moderate heights are often used to prioritise speed of contact.
-
Yes. The plyobox is a versatile platform: as well as box jumps, it can be used for step-ups, Bulgarian split squats, incline push-ups, tricep dips, plyo push-ups, seated box jumps and eccentric control exercises. The Split Squat Roller Sidea, available in Stand and Peg versions, can be used in conjunction with the box to add unilateral strength variations with movement assistance.
-
Wooden plyoboxes require regular checks of the non-slip surface and the wooden joints. Sidea offers soft-impact covers and linings (models 9112R and R9105–R9107) that allow you to convert or refurbish an existing box without having to replace it entirely. For soft plyoboxes, the foam surface should be checked periodically for any signs of compression or wear at the seams.
-
It depends on the number of athletes training at the same time and the type of programme. For group sessions involving circuit training or WODs, the rule of thumb is to have at least one box for every athlete training simultaneously. In a CrossFit box with 12–16 stations, having 8–12 boxes of varying sizes or heights allows the exercise to be scaled for different levels without interruption.
