I have a love/hate relationship with online reviews. On one hand they are great to get more information on a product especially if the description is lacking, but they can also be so jaded about a product that might otherwise be fine for my needs.

How much weight do you put behind reviews when you are shopping for products that you can't physically see or touch before purchasing?

For example: while building our registry we came across what seemed like a good mattress at BRU with great reviews (5 in total) and a great price.... Today i stumbled upon the same product on Amazon with 530 reviews listed 83% were 4-5 stars but the reviews that were 1-3 stars were rather concerning (fit issues, smell, quality not consistant, etc) Do I just cross my fingers that the one we get is in the 83% of this mattress is great?

PS: my mom already ordered the mattress so i guess I'll be able to see for myself in a few days if its a keeper but i just wanted to get other thoughts
