Getting your new mattress set up correctly from day one ensures it performs at its best and protects your warranty eligibility. Here’s the complete step-by-step setup guide for both mattress-in-a-box and white-glove delivered mattresses.

Before the Mattress Arrives

Measure your doorways, hallways, and stairwells before delivery โ€” particularly important for standard (non-compressed) mattresses. A queen mattress is 60″ wide; make sure your path from front door to bedroom is navigable. Clear the room of obstacles. Have your bed frame assembled and ready before the mattress arrives. Prepare a clean, flat surface or frame.

Step 1: Check Your Foundation

Before unboxing the mattress, verify your foundation is solid. Check slat spacing (should be under 3″ apart for foam). Confirm the frame is stable with no wobble. Check for protruding screws or rough edges that could damage the mattress cover. If using an older box spring with actual springs, place a board over it to create a flat surface.

Step 2: Unbox and Expand (for mattress-in-a-box)

Bring the box to the bedroom before opening. Place the rolled mattress on your frame or on the floor in the right position. Cut the outer plastic carefully โ€” don’t cut deep enough to reach the mattress cover. Once the vacuum seal is broken, the mattress will begin expanding rapidly. Unfurl it fully on the frame.

Money-Saving Tip: Have a mattress protector ready to put on immediately after the mattress expands. This protects trial return eligibility and warranty from the very first night, before any accidental stains can occur.

Step 3: Allow Expansion Time

Give the mattress 24-48 hours to fully expand before sleeping on it โ€” longer is better. Most foam mattresses are sleep-ready within a few hours, but full expansion (and initial off-gassing) takes longer. Ventilate the room by opening windows during this period to help clear any off-gassing smell faster.

Step 4: Break-In Period

Allow 30 nights before evaluating whether the mattress is right for you. Your body adapts to new sleep surfaces โ€” initial discomfort or unfamiliar feel is normal and usually resolves within 2-4 weeks. Track your sleep quality notes over this period for an objective evaluation before the trial period decision point.

Maintenance from Day One

Rotate 180 degrees at 30 days (and every 3-6 months thereafter). Use your mattress protector consistently. Keep the bed made to protect the cover. Follow the brand’s care instructions for any stain treatment.

Also worth considering: Layla Sleep mattresses feature copper-infused memory foam, dual firmness (flip for soft or firm), and come with a 120-night trial โ€” a strong option for value-conscious sleepers.
