Juni Postural Chair by Smirthwaite – Adjustable Pediatric Support Seating

The Juni Postural Chair by Smirthwaite is a bright, highly adjustable pediatric chair for children who need minimal postural support during learning, play, and everyday seated routines. With a contoured seat and back, built-in lumbar support, a reclining backrest, and adjustments that grow with the child, the Juni gives families, therapists, and schools supportive seating that feels welcoming rather than clinical.

At Independent Living Superstore, we see the Juni as the perfect bridge between simple classroom seating and more structured postural chairs. It offers real adjustability and positioning support while keeping a friendly, compact design that fits naturally into inclusive classrooms, nurseries, and homes. A pelvic strap is included with the chair, and a wide range of optional accessories lets you tailor the Juni to a child's exact needs.

Lime green Smirthwaite Juni postural chair with flat wooden armrests, a lap strap, and an adjustable frame.

Best For

  • Children who need minimal postural support during classroom, nursery, or home activities
  • Parents and therapists who want an adjustable chair that grows with the child
  • Schools and nurseries seeking supportive seating with a bright, inclusive design
  • Children who benefit from built-in lumbar support and contoured positioning
  • Settings that want a step up from basic classroom seating without a highly clinical system

Grows With Your Child

The Juni is built to adapt as a child develops. Seat height, seat depth, and armrest height all adjust easily, and the backrest reclines in 5° increments from 95° to 105° to fine-tune comfort and support. With four sizes to choose from and a range of add-on accessories, one Juni can keep supporting a child through years of growth and changing needs.

Support / Performance

The specially contoured seat and backrest encourage healthy postural alignment while keeping a child feeling secure and stable. Integrated lumbar support helps maintain a healthy spine position during longer periods of sitting, and the included pelvic strap adds gentle positioning. For children who need more, optional side-support cushions, a pommel, and a 4-point harness build on the chair's core support.

Maneuverability / Portability

Lightweight and compact, the Juni is easy to reposition between classrooms, therapy rooms, and home spaces, and its smaller footprint fits naturally at desks and tables. For even easier movement, optional mobility bases – including a dolly base with push handle and the gas-assisted Hi-Lo base – let you roll and adjust the chair with ease.

Comfort & Design

The Juni pairs supportive contouring with a cheerful, contemporary look that blends into modern classrooms and family spaces. Broad, flat wooden armrests give a child a comfortable, stable place to rest their arms and a natural push-off point when sitting down or standing up. Its hard-wearing Dartex fabric is available in four colors – Lime, Red, Blue, and Cobalt (Black) – so the chair feels approachable and inclusive rather than institutional. Color availability can vary by size, so reach out if you have a specific combination in mind.

Size Guide

The Juni comes in four sizes. Rather than choosing by age, match the child's seated measurements to the seat height and depth. Not sure which size fits? Call us and we'll be glad to help.

It works in classrooms, nurseries, and homes, and grows with the child through four sizes.

How does the Juni chair adjust as a child grows?

The Juni adjusts in several ways: seat height, seat depth, and armrest height all change, and the backrest reclines in 5-degree steps from 95 to 105 degrees. It comes in four sizes, so one chair can support a child through a wide growth range. Call us if you would like help choosing.

The Juni comes in four sizes, from Size 1 with a 6.3-inch minimum seat height up to Size 4 at 15.7 inches. Maximum user weight rises with each size, from 66 pounds on Size 1 to 132 pounds on Size 4. Match the child's seated measurements to the seat height and depth.

What comes included with the Juni chair?

Every Juni chair includes a contoured seat and back, built-in lumbar support, flat wooden armrests, and a pelvic strap for gentle positioning.
