Buying a mattress starts with size and type, then support testing in-store, and always a written check of trial, warranty, and return rules before checkout.
A mattress is a long-term purchase you’ll live on for nearly a third of your day, so the stakes of getting it wrong are high. Start by figuring out what you and your room need, then verify every policy in writing before you pay.
Start With Size and Sleeper Needs
Choosing the right size comes down to two factors: the sleeper’s height and the room’s dimensions. While a queen at 60 x 80 inches fits most couples, taller individuals often find a king (76 x 80 inches) or a California king (72 x 84 inches) more comfortable for length.
- Twin (38 x 75 inches): best for kids or single sleepers in small rooms.
- Twin XL (38 x 80 inches): common in college dorms; adds legroom for taller teens.
- Full (54 x 75 inches): roomy for one, cramped for two.
- Queen (60 x 80 inches): the most popular choice for couples and guest rooms.
- King (76 x 80 inches): maximum width for couples who want personal space.
- California King (72 x 84 inches): better for taller people who need more length.
Once the size fits, match the type to the sleeper. Side sleepers usually need a softer surface for pressure relief, while back and stomach sleepers often prefer firmer support to keep the spine aligned. A guest room may suit a versatile mid-firm feel, while a primary bed deserves a more personalized choice.
How to Test a Mattress In-Store
Testing in person is the only way to judge comfort. Wear comfortable clothing and plan to spend real time on each bed.
Lie in your usual sleep position—side, back, or stomach—not just sitting on the edge. Test with your partner if you share the bed, and bring your own pillow if you have a strong preference.
Pay attention to your posture.
Verify the Fine Print Before Buying
The price tag is only part of the cost, so compare across retailers before committing. Check the brand’s own site for the manufacturer’s suggested retail price to know whether a “discount” is real or just a markup game. Consumer Reports also notes its mattress tests cover durability, support, and comfort—useful benchmarks for comparing quality across brands.
The fine print is where costly mistakes hide. Before checkout, confirm the trial period, return policy, warranty coverage, and delivery details in writing—the BBB specifically advises getting refund and return terms documented. Check the mattress tag for proper labeling, and confirm the bed is compatible with your existing base or frame, since the foundation can change how firm the mattress feels.
Small details can cause big headaches later. Measure the mattress depth to ensure your sheets fit, and check the weight to make sure you can handle it when moving. If you’re buying a hybrid or innerspring, verify whether delivery includes setup and removal of your old mattress.
Common Mattress Shopping Mistakes to Avoid
Most buyer’s regret traces back to a few avoidable errors made during the shopping process. Recognizing them up front can save you both money and a bad night’s sleep.
- Buying on price alone without comparing multiple retailers or checking the brand’s reference price.
- Rushing the in-store test—judging a bed in under five minutes misses pressure points that appear later.
- Ignoring your base at home—a box spring vs. a platform can change how firm the mattress feels.
- Skipping the fine print—trial periods, return fees, and warranty exclusions vary widely.
- Overlooking logistics—mattress depth, sheet fit, and weight affect both comfort and daily handling.
Once you’ve verified every policy, the final step is a check of the warranty details: what’s covered, what’s not, and who handles the claim. Bedding warranties often exclude normal sagging or stains, so read the exclusions carefully. If you’ve done the research, tested properly, and confirmed the terms, you’re ready to buy with confidence.

FAQs
How long should I test a mattress in store?
Plan to spend at least 15 minutes lying on each mattress in your usual sleep position. This gives your body time to register pressure points that won’t appear in the first few minutes. If a store makes you feel rushed, that’s a sign to shop elsewhere.
What’s the difference between a king and California king?
A standard king measures 76 x 80 inches—wider but shorter—while a California king is 72 x 84 inches, making it longer but narrower. Choose a California king if you’re tall and need extra legroom, or a standard king if you want more width for spreading out.
Can I negotiate the price of a mattress?
Yes, mattress prices are often negotiable, especially at brick-and-mortar stores. Before negotiating, check the brand’s own site for the manufacturer’s suggested retail price, and be ready to walk away if the store won’t match a competitor’s price. Ask about price-match policies and bundle deals on frames or pillows.
