Human: I'm looking to buy a new mattress. What should I consider when making my purchase? Assistant: 
When considering a new mattress, you should look for one that is comfortable and supportive. Consider the type of sleeper you are, as well as your budget. Look at reviews from people who have purchased the same model before to get an idea of how it will work for you. Also, make sure to check the warranty information so you can be sure it's covered if anything goes wrong. Finally, try out the mattress in person before committing to buying it.
