Three decisions make the rest easier.

Start with how you sleep, compare the feel, then check the practical details. This guide gives you a small set of things to test at each step so you can leave with two or three finalists, instead of a longer shopping list.

  1. 01
    Find your feel

    Compare comfort and movement in your usual sleep positions.

  2. 02
    Check your setup

    Match the size, support and complete cost to your room.

  3. 03
    Try your finalists

    Use the same test on two or three beds before deciding.

Step 01

Start with your sleep position

Start with the position you spend most of the night in. Use these as things to test, rather than rules that choose the bed for you.

  • Side sleepers — compare cushioning at your shoulders and hips. Try a medium or softer feel, then check whether you still feel supported. Explore side-sleeper mattresses.
  • Back sleepers — notice whether your lower back feels supported and your hips settle comfortably. Compare a medium and a firmer option.
  • Stomach sleepers — check that your midsection does not sink farther than feels comfortable. Include a firmer model in your comparison. Explore stomach-sleeper mattresses.
  • Combination sleepers — turn between your usual positions. Notice how easily you can roll and whether any position feels awkward.
Step 02

Factor in your body weight

The same mattress can feel different to two people. Body weight affects how deeply you settle, but it does not assign you one correct firmness.

  • If you settle very little: compare a more cushioning surface and check for comfortable contact at your shoulders and hips.
  • If you sink farther than you like: compare a firmer feel or a different support construction.
  • If you share the bed: both people should test it. One person's comfort rating cannot stand in for the other's.
Step 03

Choose a mattress type

Boxed is a delivery format, not a mattress type. Foam and some hybrid models can arrive compressed. Compare the exact construction and feel, then check unpacking, expansion and handling instructions in the boxed-mattress setup guide.

Choose the feel you enjoy, then compare individual models. Construction alone does not guarantee firmness, cooling or comfort. Explore mattress types in more detail.

Memory foam

The feel: close contouring, often with a slower response.

Test this: roll over and check how easily you can change position.

Hybrid

The feel: comfort layers over a coil support core, combining cushioning and spring.

Test this: compare the surface feel, movement transfer and edge on the exact model.

Shop hybrid mattresses

Latex

The feel: buoyant and responsive, with less of a slow sinking sensation.

Test this: decide whether you like its pushback and how it moves with you.

Innerspring

The feel: a traditional spring mattress; the top cushioning varies by model.

Test this: lie down as well as sitting on the edge, and compare the cushioning.

Step 04

Understand the firmness scale

Firmness describes the surface feel; support describes how the mattress holds you. A firmer label does not automatically mean a better fit. Labels and numerical scales also vary between brands.

  • Soft / plush: more surface cushioning. Check whether you sink farther than you want.
  • Medium: a useful comparison point when you are unsure. Check it in all your usual positions.
  • Firm: less surface give. Check that it still feels comfortable at your pressure points.

Try two adjacent feels in the same model range, using the same pillow. Describe what you feel instead of relying on the number.

For a closer comparison, use the firmness and support guide.

Step 05

Pick the right size

Measure both the sleeping surface and the outside of your frame. Queen is 60 × 80 inches; King is 76 × 80; CA King is 72 × 84. King adds width over Queen, while CA King adds length.

Mark the frame footprint on your floor and check your doors, drawers and walking routes. For two people, try the size together before ordering.

Use the Room Fit Planner or read the complete mattress size guide.

Step 06

Temperature regulation for hot sleepers

Compare the whole sleep setup: mattress construction, cover, protector, sheets and room temperature. A cool-touch cover describes how the surface feels; it is not a promise that you will stay cool all night.

Ask what the specific model does to manage warmth and compare how closely each surface hugs you. Explore cooling mattresses.

Step 07

If you share the bed

Try the sleeping surface together. Confirm mattress and base compatibility before choosing an adjustable setup.
  • Movement: have your partner turn over or get out while you lie still.
  • Space and edges: lie where you normally sleep, including near the edge. Check sitting and getting up, too.
  • Different preferences: compare both of your needs. A Split King uses two Twin XL mattresses and can allow different feels on each side.

Independent elevation requires a compatible split adjustable setup; a single shared base does not adjust each sleeper separately. Compare Split King mattresses and adjustable beds.

Step 08

Special needs

Bring up the everyday details that matter to you: getting in and out, sitting at the edge, changing position, or using an existing base. Try those movements before deciding.

  • Comfort concerns: describe where you feel pressure and which positions you find comfortable. Avoid choosing solely from a claim about back pain.
  • Bed height: consider the combined height of the mattress and foundation or base.
  • Adjustable compatibility: confirm the exact mattress and base pairing with the manufacturer requirements before ordering.

Ask our team about your setup.

Check whether replacement is the next step

Note changes in comfort, visible damage or unevenness. Check the foundation and the manufacturer’s care instructions before assuming the mattress alone is responsible. Age is a prompt to inspect, not a universal expiry date. If something may be a covered defect, document it and check the warranty process before disposing of the bed.

Step 09

Materials and certifications

A closer look at cushioning layers. Materials and certifications vary by model.

First check the layers in the exact model: the cushioning you lie on, the support underneath and the cover around it. Then check any certification against the component it actually covers.

A certification can help you evaluate materials; it does not tell you how comfortable that bed will feel. Ask for the specific model’s certificate instead of relying on a general brand badge.

Plan for care, not just purchase day

Confirm required base support and whether the manufacturer permits rotation or flipping. Follow the model’s cleaning instructions; do not assume every mattress can be treated the same way. Compare a compatible mattress protector and keep your receipt and model details.

Step 10

Set a realistic budget

Set a total budget before comparing upgrades. Include the mattress, a compatible foundation or adjustable base if needed, a protector, bedding and any delivery services.

Compare the same size and included items. A higher price does not automatically make one mattress more comfortable for you. See what to consider at each budget or browse current mattress offers.

If you plan to finance, compare the total cost and terms. See financing and lease-to-own options before applying.

Should you wait for a sale?

Compare the same model, size and included services against your written quote. Check current availability and the offer’s end date; a holiday label does not guarantee the lowest total price. If you need a bed by a move-in date, confirm delivery timing before choosing an offer.

Step 11

Trial periods and warranties

An exchange policy and a manufacturer warranty cover different things. Check both before you buy.

  • Comfort exchange: read the eligibility, minimum sleep period, service fee and exclusions in the 120-Night Love Your Bed Guarantee. It is a comfort exchange, not a blanket refund promise.
  • Warranty: check the exact model's covered defects, required support and claim instructions. Start with our warranty guide.

Verify delivery and setup before payment

Get the exact model, firmness, size, included items, fees and estimated delivery window in writing. Measure doorways, stairs and elevator access; ask your building about reservations or delivery requirements. Confirm whether setup and old-mattress removal are included, optional or unavailable for your order. See the current delivery and setup information.

Step 12

How to test a mattress in the showroom

Give each finalist the same test so you can compare it fairly.

  1. Lie down in your usual position. Use the same pillow as you move between mattresses.
  2. Take your time. Try spending 10–15 minutes on each finalist instead of judging it from a quick sit.
  3. Check comfort and movement. Notice pressure, how far you settle and how easily you turn.
  4. Test it together. If you share a bed, check movement transfer and personal space with your partner.
  5. Record your top two. Save the model, feel, size and what you liked, then ask about availability and delivery.

Find a showroom and confirm what is on display.

Use the detailed showroom testing guide for the focused comparison routine.

Step 13

Common mistakes to avoid

  • Choosing from the label alone. Compare two nearby feels and describe what changes for you.
  • Trying it only while seated. Lie down, turn over and test your usual sleeping positions.
  • Comparing different packages. Use the same size and account for the base, accessories and delivery.
  • Buying space that will not fit. Measure the complete frame, access route and room clearances.
  • Letting one person decide for two. Both sleepers should try the finalists together.
  • Skipping the small print. Read the exchange eligibility, fees and model-specific warranty requirements.

How to use this at LA Mattress

Compare online and in-store buying

Online research lets you compare specifications and written terms at your own pace. A showroom lets you compare how the beds actually feel. You can use both: research a shortlist, confirm the exact models on display, then decide where to order. Do not assume one channel is always cheaper or has easier returns; compare the complete quote and seller-specific policy.

Use the LA shopping-location guide to plan a visit. For an apartment delivery, confirm your building’s access requirements before booking.
