A Beginner's Guide to Buying a Mattress

Buying a new mattress

If you're sleeping on an old mattress, you might not be getting the rest you need. Whether your toddler is graduating to a bigger bed or you need a new king for the master bedroom, finding the right mattress can be daunting. Here are some types, tips and features to consider when buying a mattress.

Types of Mattresses

Innerspring Mattresses

Built with a core of steel springs, these mattresses offer a variety of comfort levels. The various coil constructions deliver a unique feel and ample support.


  • Ideal for side sleepers - The sleeping surface is built to handle the increased pressure that comes from sleeping on your side.

  • Diverse comfort - Innerspring mattresses have different coil systems that provide sleepers with proper support and comfort to enjoy a peaceful night's sleep. They also come in a wide variety of top layers to suit any sleeper's needs. 

  • Proper ventilation - The spring-filled core doesn't trap heat, helping you and your partner stay cool all night long.

Constructed of a highly malleable foam, these beds will perfectly contour to your body. If you're looking for a sleep solution that uniquely forms to you, this is the model you need.

  • Specialized construction - These types of mattresses are constructed with polyurethane materials. Some options use hypoallergenic alternative foam made from latex. 

  • Easily adjust from firm to soft - Memory foam conforms to your body's shape and evenly distribute body weight, which helps provide better comfort and support to these areas. The surface adjusts from firm to soft based on cool and warm body temperatures, respectively.

  • Ideal for couples - Since these models let your body sink into one spot, they also reduce heavy motion transfer. This allows sleepers to move without disrupting their partners.

Hybrid Mattresses

These mattresses combine the best of both worlds. The innerspring core delivers ample support, while the memory foam layer provides comfort.


  • Comfortable construction - The mattress is typically constructed with a pocket-spring core and a 3-4" foam surface.

  • Seamlessly combines comfort and support - For sleepers that require top-tier support and pillow-like comfort, a hybrid mattress is the perfect choice. Its coils provide plenty of flexibility while the memory foam properly adjusts to your body weight.

  • Works best with adjustable beds - Most hybrid models are constructed with pocket coil cores, which reduce motion transfer on each side of the mattress. This configuration fits perfectly with adjustable bases, allowing you to comfortably sleep, watch TV or read a book.

Things to Consider

Before you dive deeper into your research, there are many factors to consider when buying a new mattress. Keep the following things in mind when looking for the right one.

Things to consider when buying a new mattress
  • How do I sleep? - Your sleeping patterns matter when choosing the right mattress. Make sure your new sleeping surface is made of materials that cater to your habits.

  • Size matters - Size is key. Do you prefer more room to sprawl out? Is your bed for two or just you? How tall is the sleeper? Don't forget to consider how much space is available in the room. For example, a small master bedroom might hold a queen bed better than a king. 

  • Which features matter - There are many new features that play a role in how you sleep. Cooling gel layers, updated memory foam and allergen-resistant materials are just a few of the latest innovations on the market. Research how these different features help you get a peaceful night's sleep.

  • When to buy one - There are many reasons to upgrade your mattress. Have you outgrown the sleeping surface? Is your current mattress lumpy or worn out? Are you moving into a new home with more or less space?

Popular Mattress Technology

New mattress technology delivers even more comfort, durability and an overall better night's sleep. Let's take a look at some of the available options you can choose from for your next bed.

  • Cooling - For many, keeping cool at night is key to restful sleep. Gel-foam constructions don't trap heat like original memory foam, keeping you cool at night. Ventilated memory foam mattress toppers will allow for a better flow of air while delivering serious comfort. 

  • Support - Most of your body weight rests in your core in bed. New sleeping surfaces have added ample support to that section to keep you comfortable. Mattress manufacturers have also added increased support around the edges so you don't slip. 

  • Hypoallergenic materials - Synthetic materials like memory and gel foams are best if you're an allergy sufferer. Their solid construction reduces the amount of dust mites that collect in the bed, and they're easy to vacuum or clean. For added protection, slip covers help create another barrier to allergens that can attach themselves to your mattress.

  • Adjustable basesFinding the right position isn't always as easy as rolling over. Adjustable bases allow you to create a unique sleep position wtih the press of a button. Whether you want to take pressure off your back or help relieve some snoring, these bases offer a variety of advantages for finding that sweet sleep spot.

Mattress Dimensions
