Twin Size Mattress Buying Guide

Here at Mattress Advisor, we know that shopping for a new mattress can be confusing. With so many options on the market these days, it’s hard to know which is the best mattress to suit your needs.

In this guide, we’ll go over

• Benefits of a Twin Mattress
• Twin vs. Twin XL
• What to Consider When Shopping
• FAQs

Benefits of a Twin Mattress

One of the first decisions you have to make upon buying a new mattress is which size bed you want. A twin mattress is the smallest size you’ll find on the market. A twin is a great option for kids who are growing and don’t need much space. 

Twin mattresses can be great options for smaller adults or for people who want to save space in a room. Twin-size beds are also a popular option for furnishing guest rooms. A twin’s small dimensions can save you a lot of money compared to a full, queen, or king. They are also ideal for shoppers furnishing small rooms or studio apartments as they allow for more space.

Twin vs. Twin XL

If you’re considering purchasing a twin mattress, make sure you ask yourself: Do I want a twin or a twin XL? Before you buy any mattress, you should understand the difference between these two sizes. 

The two types of twin mattresses are the regular Twin and the Twin XL. A twin XL is essentially a longer version of a twin mattress. A regular Twin is 38” x 75” whereas a twin XL is 38” x 80”. The Twin XL provides an additional 5 inches in length, perfect for those who need more leg room.

A twin XL is ideal for taller individuals who require more leg room. Twin XL mattresses are also common for college student dorm beds.

Regular twin beds, on the other hand, will work perfectly for shorter individuals, children, and small spaces. Your child can grow and sleep on a twin mattress for many years.

What to Consider When Shopping

Sleeping Position

• Side sleepers: Side sleepers will want a mattress that offers good pressure relief. If you sleep on your side, you may be prone to experiencing heightened tension in your hips and shoulders. In addition to pressure relief, side sleepers will want a mattress that offers good spinal alignment. Otherwise, you may sink too far into the mattress, causing you back pain. 
• Back sleepers: Back sleeping is said to be the best sleeping position for your spine, neck, and back and is known to promote good posture. However, if you sleep on your back, it’s also important that you pick the right mattress. Back sleepers tend to be most comfortable on medium-firm mattresses. Also, you will want a bed with a contouring ability to support your body. 
• Stomach sleepers: If you prefer to sleep on your stomach, you are unfortunately more prone to experiencing lower back pain. To counter this, you should look for a medium-firm mattress with a soft top layer and excellent pain-relieving properties.

Age

• Toddlers: When buying a bed for your toddler, safety and support should be the priority. Consider buying a softer, plush mattress for maximum comfort. Also, be sure the bed is a comfortable height from the ground so your child can climb in and out without the risk of injury. 
• Kids: A kid-friendly mattress should be comfortable, safe, and affordable. While mattresses can get expensive, it’s not necessary to spend more than $500 on a child’s mattress that they’ll eventually grow out of. If your child has allergies, consider a hypoallergenic mattress such as one made with organic latex materials. 
• Teenagers: Teenegers need a mattress that accomodates their growth spurts and active lifestyles. Athletes, especially, will benefit from a bed that comes with cooling and pressure relieving properties.
• Adults: Consider the mattress’ materials (latex, coils, memory foam, or hybrid), its firmness level (soft, medium-firm, or firm), and other additional properties it offers such as pressure point relief, cooling, motion isolation, and more.

Bed Frame

There are many kinds of frames compatible with twin mattresses, including box springs, bunk beds, trundle beds, and day beds. Box springs are the most common and easy to find. Bunk beds are popular among children, while trundle beds and daybeds provide more sleeping space and storage.

Trial and Warranty

When you purchase an online mattress, make sure you read the fine print before placing your order. 100-day trial periods are the most common, but some brands offer full-year trial periods. 10-year limited warranties are the most common, but some companies like Nectar offer lifetime warranties. 

FAQs

How much should a good twin mattress cost?

While mattresses can get very expensive, you don’t need to pay a high sticker price for a quality twin bed. A good twin mattress should cost you roughly $200-$600.

Is a twin mattress good for adults?

Twin mattresses are fine for average-sized, and especially petite, adults. Taller individuals will likely prefer a twin XL over a regular twin as it offers more leg room. Twin mattresses are not ideal for couples who share a bed.

Should I get a twin or a full bed?

Deciding whether to buy a twin or a full bed depends on your needs and sleeping arrangement. Do you sleep with a partner? If so, you’ll be more comfortable in a full size bed. Are you trying to save space in a small room? Then go for a twin or twin XL. 

Buying a bed for your kid? A twin should do the trick. A regular Twin bed’s small dimensions are perfect for shorter individuals, children, and for maximizing space in smaller rooms.
