Why Dual-Purpose Design Matters:

Most people need both seat and back support, but buying separate cushions can be expensive and cluttered. The Adjustable Seat/Back Cushion's versatile 17" × 17.5" size works perfectly on chair seats to relieve pressure points or on chair backs to provide lumbar support. The removable foam insert system allows you to customize the cushion differently for each use — firmer for seat support, softer for back support, or vice versa based on your needs.

Memory Foam vs. Standard Foam:

• Memory Foam: Conforms to your body shape, provides pressure relief, ideal for those who prefer softer, contouring support, excellent for seat cushion use
• Standard Polyurethane Foam: Firmer, more supportive, maintains shape better, ideal for those who need structured support, excellent for back cushion use

Ideal For:

• Office workers experiencing back pain, hip pain, or tailbone discomfort from prolonged sitting
• Anyone with inadequate seat cushioning or lumbar support in their current chair
• People recovering from back, hip, or tailbone injuries
• Individuals with sciatica, coccydynia (tailbone pain), or lower back conditions
• Drivers who spend long hours in vehicles
• Wheelchair users requiring customized seat or back support
• Pregnant women needing additional comfort and support
• Anyone seeking to prevent pain and improve sitting comfort
• People who need both seat and back support but want one versatile solution

What's Included:

• Adjustable Seat/Back Cushion with removable foam inserts
• Removable, washable cover
• Velcro attachment strips
• Adjustable elastic strap
  

How to Customize Your Support:

1. Start with all foam inserts in place
2. Sit on cushion (for seat use) or lean against it (for back use)
3. Assess the support level and comfort
4. Remove or reposition inserts to adjust firmness and contour
5. Fine-tune until you achieve comfortable, supportive fit
6. Cushion should provide support without feeling too firm or too soft

Proper Use Tips:

As Seat Cushion:

• Place cushion on chair seat with thicker portion toward back
• Sit all the way back in chair
• Ensure cushion doesn't raise you too high (adjust chair height if needed)
• Weight should be distributed evenly across sit bones

As Back Cushion:

• Place cushion at the small of your back (lumbar region)
• Bottom of cushion should align with your belt line
• Adjust chair backrest angle to 100-110 degrees
• Cushion should fill lumbar curve without pushing you forward

Care Instructions:

• Remove cover and machine wash cold, gentle cycle
• Air dry or tumble dry low heat
• Spot clean foam inserts as needed
• Do not machine wash foam inserts
• Regular cleaning maintains hygiene and extends product life
