Mattresses From 6 Inches to Over 14 Inches In Height

Mattress height affects comfort, support feel, the look of your bed, and how well it fits frames like bunks, trundles, and platform bases. Shop By Mattress Height organizes our assortment so you can quickly compare profiles and pick the thickness that suits your space—Canada‑wide.

Choose by height

• 6‑Inch Mattresses (≈15 cm)
  Sleek, low‑profile builds that fit bunks, trundles, daybeds, and RVs. Great for tight spaces and kids’ rooms where guardrail/clearance matters. Typically firmer and lighter for easy handling.

• 8‑Inch Mattresses (≈20 cm)
  Still low profile with added comfort layers. A smart balance for guest rooms, apartments, or minimalist setups on platform frames.

• 10‑Inch Mattresses (≈25 cm)
  A versatile “just‑right” height across foam, hybrid, and pocket coil designs. Popular for couples and primary bedrooms thanks to balanced pressure relief and support.

• 12‑Inch Mattresses (≈30 cm)
  Deeper comfort stacks for enhanced contouring, edge support, and motion control. A favourite for master suites and adjustable bases.

• Thick Mattresses (14‑Inch+ / ≈36 cm+)
  Luxuriously plush profiles with substantial comfort layers. Ideal when you want a high‑end look and feel—pair with deep‑pocket sheets and confirm headboard/footboard clearance.

Fit & setup tips (Canada‑wide)

• Total bed height: Add mattress thickness to your foundation or platform height to reach a comfortable get‑in/get‑out height.

• Bunks & safety: Ensure the mattress height meets your bed manufacturer’s guardrail guidance.

• Sheets & protectors: Use deep‑pocket or extra‑deep sheets for 14‑inch+ profiles; slim pockets suit 6–8‑inch options.

• Room flow: Lower profiles can open up small rooms; thicker profiles create a plush, statement look.

• Delivery: Many heights are available as mattress‑in‑a‑box for easy shipping and setup across Canada.
