Buying Guide: Key Considerations For Mattress Gap Fillers

  • Gap width and mattress size: Measure the distance from the headboard to the mattress to choose a model that covers 0–7 inches or 0–6 inches effectively.
  • Material and firmness: High-density foam provides durable support; memory foam offers contouring comfort. Consider a cover that is removable and washable for easy care.
  • Form factor: Triangular wedge designs fill space efficiently; foldable or adjustable models can adapt to different bed setups and gaps.
  • Storage features: On-board pockets add practical storage for remotes, phones, glasses, and books, reducing night clutter.
  • Ease of cleaning: Removable covers and washable fabrics help maintain a neat bedside area.
  • Durability and shape retention: Look for foam that holds shape after prolonged use to avoid repeated adjustments.
  • Sleep positioning: If you prefer a flatter surface, choose models with a more rectangular form or a curved top that supports your head and neck alignment.
