Losing sleep over choosing a new mattress? Laweekly.com created the following mattress guide to help make this decision process easier for you. The most important factors involved in choosing a new mattress have been highlighted below.

Replacing your mattress can be exhausting. Navigating the stores and websites, debating between foam and springs, and determining how much to spend can leave you feeling like you need a good nap.

Instead, skip the stress and follow these tips from Lexie Sachs, Senior Textiles Analyst at the Good Housekeeping Institute, that will help you navigate the world of mattresses.

Where to Shop for a Mattress
Laying down in the store isn’t the only way to go anymore. New mattress-in-a-box companies have won over thousands of customers with convenient shipping and free trial periods. Online mattress buying has seen a serious boom, but it’s not right for everyone. Here’s what you need to know.

Shop in the store if…
Go the traditional route if you want a greater variety and to feel them before buying. In a mattress store, you should never pay full price. Always shop the sales, and don’t be afraid to negotiate with the salesperson. Most stores will also offer removal of your existing mattress. The downside is it can feel overwhelming and it’s harder to compare prices to know if you’re getting a good deal. A big mistake is rushing the decision by quickly lying down on many different mattresses to find the one that feels best. If you’re going to invest in a mattress, take the time to recline for a while (at least 10 minutes) and make sure you don’t feel any pressure or pain.

Shop online if…
This newer route offers a great alternative if you have trouble making decisions, since there are fewer options. Plus, you can shop from home! These mattresses generally arrive in a box at your doorstep within a few days and include free shipping and a money-back guarantee (even if you simply don’t like the mattress!) so there’s minimal risk. Online, the price is usually final, but it doesn’t include markups for being sold at a physical store. The downsides are that you typically have to set it up yourself and deal with getting rid of your old mattress.

Either way, always ask about the return policy. Not happy with your pick? You may get a partial refund if you bought it in a store, but online companies often arrange to pick it up for a local charity and will give back 100% of your money. Make sure you can test out a new mattress for a month risk-free; that way, you can get used to it before making a decision.
