2026 portable pressotherapy comparison: maximum pressure, chambers, and value for money

If you are looking for the best value for money in portable compression therapy, Sizen 6e offers 6 independent chambers and up to ~240 mmHg at a competitive price; if you need more chambers, Sizen 8 Pro features 8 independent double-layer chambers and a battery. Both options ensure exceptional, comfortable muscle recovery anywhere.

Key points:

• Sizen 6+ NEW: The all-round option for those seeking professional quality without overspending. It has 6 independent chambers, 4 massage modes, and 6 hours of battery life for around €849 (offer).

• Sizen 8 Pro: Designed for the most demanding users, high-performance athletes, or professional use. It features 8 overlapping double-layer chambers, 6 massage programs, 6-hour battery life, and an included carrying bag for around €999 (offer).

• Power and total control: Both models reach up to 250 mmHg of maximum pressure, are conveniently managed from the Sizen App via Bluetooth, and come backed by a 3-year official warranty.

What maximum pressure in mmHg do I need?

In compression therapy, regulated pneumatic pressure is the key force that supports circulatory and lymphatic drainage. Although in day-to-day use it is normal to work in ranges between 90 and 120 mmHg for a relaxing recovery session or progressive lymphatic drainage, having equipment capable of reaching 250 mmHg - as is the case with the Sizen range - makes a huge difference.

Having that extra power range does not mean you have to use maximum pressure in every session; it means the compressor works effortlessly, without overexertion, while maintaining a constant flow of air throughout the entire cycle. This ensures deep treatment when your legs are truly worn out after a demanding workout, while also extending the machine's service life.

How many air chambers are best?

The number of chambers is not just a technical detail: it determines how progressive and fluid the massage feels from the foot to the groin. The more chambers the boot or trousers have, the smaller the pressure "jump" between areas and the smoother the compression wave:

• 6 chambers (Sizen 6+ NEW): The sweet spot for the vast majority of users. It allows highly precise, segmented treatment by area (foot, calf, knee, quadriceps, etc.), activating return circulation very effectively without breaking the budget.
• 8 chambers (Sizen 8 Pro): The high-demand level. With 8 overlapping chambers (featuring a double-layer design), not a single millimetre of the leg is left without pressure. The "gaps" between each section are completely eliminated, creating the sensation closest to a therapist's hands working on the leg in a continuous cycle.

Which offers the best value for money?

The answer depends on your lifestyle and the type of recovery you are looking for.

If your goal is to relieve your legs after going for a run, cycling, or simply easing accumulated fatigue after spending many hours on your feet, the Sizen 6+ NEW represents the most balanced purchase in terms of cost and performance. For around €849 on offer, you get professional 250 mmHg compression equipment, 6 hours of battery life for use on the sofa or while travelling, a touchscreen, and full control via the App.

By contrast, if you train daily at high intensity, compete, or want to get the most out of every recovery session, upgrading to the Sizen 8 Pro (around €999 on offer) is absolutely worthwhile. You not only gain 2 extra chambers per leg with continuous overlap, but also 2 additional massage programs (such as Double Wave or Triple Pulse) and the included carrying bag to take it with you anywhere.

How do Sizen 6+ NEW and Sizen 8 Pro compare?

To help you make the decision at a glance, here is a summary of the key specifications of both models:

Frequently Asked Questions (FAQ)

What exactly does it mean for the chambers to be "overlapping"?

It means that the air pockets inside the garment overlap slightly (double-layer technology), like roof tiles. This way, when the air moves from one chamber to the next, no intermediate areas are left without compression. In the Sizen 8 Pro, this translates into continuous, fluid drainage without pressure loss at the folds.

How long does the battery last and how long does it take to charge?

Both Sizen 6+ NEW and Sizen 8 Pro feature an integrated lithium battery that provides up to 6 hours of battery life per charge (enough for 8-10 complete sessions without depending on a power outlet). A full charge from empty takes around 3 hours.

Can I control the compression therapy directly from my mobile phone?

Yes, completely. Both devices have Bluetooth connectivity and pair with the official Sizen App (for iOS and Android). From the app, you can change the program, adjust the intensity chamber by chamber, turn specific areas on or off if you experience any discomfort, control the time, and save your preferred settings to start your sessions instantly.
