Before you even start shopping and asking specific mattress questions, make sure you know how this retailer takes care of their customers. Buying a mattress is a big commitment. You're going to have questions or concerns as you set up and experience your mattress in real life. It's important to know where to turn when this happens. If you have a question or concern after your new mattress arrives, is there someone who can help you? Who do you call-the retailer or the manufacturer? What kind of help can they give? Ask for names, email addresses and phone numbers of contacts, and remember to ask the representative to be as specific as they can be. If you don't get a clear answer, you'll know that this mattress retailer may be difficult to reach if you have any problems with your purchase.
