Mattress reviews are tricky, especially online. To get the most benefit, first get to know which brands and models appeal to you while staying within your budget.
Objective evaluations from real consumers who have actually slept on the bed for a good period of time are certainly valuable. But there are a few things to keep in mind.
If you considering buying a mattress, make sure the review addresses your biggest concerns — comfort and quality. Problems with the salesperson or the buying transaction should be secondary, as you most likely will be buying your mattress from a different place.
