  3. Too low: forces you to slump in order to use them, straining your shoulders

• Should support the even distribution of your weight with no pressure points
• Feet should rest flat on the floor
• Avoid a seat that's too cushioned or has too much "give" for your body; makes changing positions difficult and weakens support
• Seat should have sloping "waterfall" edge to promote circulation
• Should provide an inch clearance between the seat cushion and the back of your knees
• Quality seat cushions have thicker foam; thinner, less cushioned foam loses shape and support over time
