Chirp - Wheel+ 3-Pack

Chirp's own store tags the Wheel+ 3-Pack as its best seller: three wheel diameters for stepping pressure up or down, $71.99 for the set.

The Chirp Wheel+ 3-Pack bundles three foam-padded back wheels in 4, 6, and 10 inch diameters. Each wheel has a center groove Chirp calls the Spinal Canal, a recessed channel that keeps direct pressure off the vertebrae while the padded surface presses into the muscles on either side of the spine. You lie back on the wheel and roll; diameter sets intensity, with the wide 10 inch wheel giving the shallowest stretch and the 4 inch wheel concentrating the most pressure into one spot.

The math on the bundle checks out. On 2026-08-06 the singles listed at $23.99 for the 4 inch Focus, $27.99 for the 6 inch Deep Tissue, and $31.99 for the 10 inch Deep Stretch, a combined $83.97 against the set's $71.99. That is about $12 saved, plus the 6 inch single was showing sold out on its own product page while the 3-pack remained in stock. The store also lists an $89.99 compare-at price on the bundle, so the everyday price already sits below the sticker.

Know what you are buying: this is an unpowered foam and plastic tool. There is no vibration, heat, or percussion, and the depth of the work depends entirely on how much body weight you load onto the wheel and how controlled your rolling is. You also need floor space and the ability to get down to the ground and back up comfortably. Chirp's marketing ties the wheels to back tension, posture work, and sore muscles along the spine; read those as the brand's positioning, and bring persistent back issues to a professional rather than a foam wheel.

If you already roll on a smooth wheel and want more aggressive, textured pressure, Chirp's XR line covers that for $18 more per 3-pack. As a first back wheel, the smooth Wheel+ set is the sensible starting point, and the three sizes mean you are unlikely to outgrow it in either direction.
