Ultimate Sack Instructions & Care

Ultimate Sack Instructions & Care

Everything you need to set up, break in, protect, and refresh your Ultimate Sack for years.

Quick note: Your Sack may look β€œlumpy” at first. That’s normal during expansion and break-in.

Setup & Unboxing

What’s in the box

  • Outer cover (removable)
  • Inner liner (holds the foam)
  • Foam (pre-filled inside the liner) (or ships separately depending on your model)

Step-by-step setup

  1. Bring the box inside and open it carefully (avoid using a deep blade).
  2. Remove the cover + liner bundle and place it on a clean floor.
  3. Let it expand for 24–48 hours for best loft.
  4. If your cover isn’t installed, put it on starting from the base, pull evenly, then zip closed.
Pro tip: Expansion looks uneven at firstβ€”give it time and a few fluff sessions.

Break-In & Fluffing

Your Sack will soften over timeβ€”that’s where the comfort comes from.

First-week routine

  • Day 1–2: Let it expand fully.
  • Day 3–7: Fluff once per day (30–60 seconds).

How to fluff (fast)

  • Grab two sides and lift/shake.
  • Roll it forward once or twice.
  • Punch down the center to form your seat pocket.

If it feels too firm

  • Use it daily for a weekβ€”foam relaxes with real use.
  • Do a few gentle β€œseat drops” to help it settle.

Shaping Guide

Lounging

Mound higher behind you to build a soft backrest.

Gaming

Create a lower seat pocket + taller back for posture support.

Reading

Build a β€œwedge” shape and keep the top corners fuller.

Naps

Flatten evenly, then fluff the edges like a pillow border.

Optional: Add 2–3 simple photos here showing each shape.

Refilling / Adding Foam

When should I add foam?

  • If it feels noticeably flatter after months of heavy use
  • If you want a firmer feel

How to add foam

  1. Unzip the outer cover.
  2. Locate the liner zipper.
  3. Add small amounts at a time (a little goes a long way).
  4. Zip the liner fully before putting the cover back on.
Important: Avoid overfillingβ€”it reduces the β€œsink-in” comfort.

Everyday Care

  • Rotate your Sack weekly to keep wear even.
  • Keep away from direct heat sources (space heaters, fireplaces).
  • Avoid prolonged direct sunlight to help prevent fading.
  • Keep sharp objects away (pet nails, tools, belt clips).

Spot Cleaning

For small spills

  1. Blot immediately (don’t rub).
  2. Use mild soap + water on a soft cloth.
  3. Dab, then blot dry.
  4. Air dry completely.
Do not: soak the foam/liner.

Cover Washing

Use the guidance below as a safe baseline. If your specific cover has a care tag, follow that first.

Most removable covers

  • Wash cold, gentle cycle
  • Mild detergent only
  • Air dry or tumble low (if fabric allows)

Sherpa / plush-style covers

  • Cold wash
  • No fabric softener
  • Air dry recommended to keep texture

Performance / woven covers

  • Cold wash
  • Tumble low if permitted
  • Zip closed before washing to protect the zipper

Always

  • Wash cover only (not foam/liner unless designed for it)
  • Test any stain remover on a hidden area first

Stain & Odor Guide

  • Food/grease: blot β†’ mild soap β†’ repeat (don’t heat-dry until gone)
  • Mud: let dry β†’ vacuum/brush β†’ spot clean
  • Pet accidents: enzyme cleaner (fabric-safe) β†’ air dry fully
  • Smoke/odor: baking soda on cover overnight β†’ vacuum β†’ wash cover

Kid & Pet Tips

  • Use a washable throw blanket for heavy daily use.
  • Trim pet nails to prevent snags.
  • Consider a secondary β€œeveryday” cover if you swap styles seasonally.

Safety Notes

  • Keep foam away from small children (choking hazard if accessed).
  • Do not open the liner around kids/pets.
  • Not intended for use near open flames/high heat.
  • Use on stable flooring to help prevent sliding.

FAQs

Why is it lumpy?
Normal during expansion. Give it 24–48 hours, then fluff daily for a week.
How long does it take to feel perfect?
Most people love it within 7–14 days as the foam breaks in.
Can I wash the foam?
Noβ€”wash the cover only. Keep the liner/foam dry.
My cover is tight. Is that normal?
Yes. That’s common on first install. Work it on from the base evenly; it loosens slightly with use.
How often do I add foam?
It depends on usage. Many customers don’t need to for a long time, but you can add foam anytime for a firmer feel.
