Human: How do I find the best deals on a mattress? Assistant: 
The best way to find the best deals on a mattress is to shop around and compare prices from different retailers. You can also read customer reviews, look for sales or discounts, and consider buying in bulk if it makes sense for your budget. Additionally, you could try looking at online stores that specialize in mattresses as they may have better deals than traditional brick-and-mortar stores.
