Determine your sleep position (side, back, stomach) and choose support accordingly
Identify your preferred feel (soft, medium, firm)
Match firmness to body weight to avoid misalignment or bottoming out
Consider pressure relief needs (hips/shoulders)
Choose appropriate support for the spine (keep hips level with shoulders)
Decide on mattress type (innerspring, hybrid, memory foam, latex, adjustable air)
Evaluate motion isolation if you share the bed
Check temperature regulation (cooling cover, breathable materials, open-cell foam, latex, coils)
Assess edge support if you sit or sleep near the edge
Confirm ease of movement (avoid excessive sink for combination sleepers)
Look for durability and warranty length (and what is covered)
Verify sleep trials and return policy
Check for certifications and materials safety (e.g., CertiPUR-US for foam)
Consider allergies and off-gassing (low-odor options, breathable covers)
Ensure compatibility with your bed frame and foundation (slats spacing, platform requirements)
Measure your space and mattress height requirements
Use a head-to-toe fit test in-store or follow trial guidance online
Reassess based on comfort after settling time (new mattress break-in expectations per brand)
If you have pain or medical needs, prioritize pressure relief and spinal alignment and consult a clinician if necessary
