How to Fit Sofa Covers Over a Sofa Bed: A UK Homeowner’s Guide (2025)

Sofa beds combine seating and sleeping functions, but their folding mechanisms and thicker mattresses make fitting sofa covers a challenge. A poorly fitted slipcover can bunch up, restrict movement, or tear when the bed is extended. In this guide, we’ll break down how to choose and install couch covers for sofa beds, featuring SofaCoverUK’s stretchable designs tailored for UK furniture.

1. Key Challenges of Sofa Bed Covers

  • Thick Mattresses: Adds height when folded, requiring extra fabric depth.

  • Moving Parts: Hinges and pull-out mechanisms can snag non-stretch fabrics.

  • Dual Functionality: Covers must stay secure in both sofa and bed modes.


2. Step-by-Step Fitting Guide

1️⃣ Measure the Sofa Bed:

  • Folded Dimensions: Length, width, and height (including arms and backrest).

  • Mattress Thickness: Critical for depth—measure when folded and unfolded.
    2️⃣ Choose Stretchable Fabric: Opt for polyester-spandex blends (like SofaCoverUK’s sofa bed cover above) that expand over the mattress.
    3️⃣ Install in Sofa Mode:

  • Drape the cover evenly, tucking excess fabric into crevices.

  • Secure elastic edges around the base and arms.
    4️⃣ Test Bed Mode: Extend the bed gently to ensure the slipcover doesn’t restrict movement or tear.

7. Maintenance Tips

  • Wash Monthly: Remove dust and allergens from mattress contact areas.

  • Air Dry: High heat shrinks elastic edges.
