Memory Foam Mattresses

Browse our comprehensive collection of memory foam mattresses, organized by construction type, firmness level, and specific sleep benefits. Our range includes pure Visco foam models designed for deep contouring and hybrid options that combine foam layers with pocket springs for responsive support. Available in all standard UK sizes, from compact singles to spacious super kings, this selection allows you to compare different compositions to find the right sleep surface for your home.

Find solutions tailored to specific sleep challenges, such as chronic back pain, joint sensitivity, or partner disturbance. For those seeking pressure relief, our high-density foam options distribute weight evenly to support spinal alignment. If overheating is a concern, look for our "Cool Blue" designs which utilize open-cell technology for better airflow. Couples can also explore models with superior motion isolation, ensuring movement on one side of the bed remains absorbed.

Navigate the collection by comfort grade, focusing on the medium-firm feel preferred by most UK sleepers, or filter by convenience features like our vacuum-packed memory foam mattress in a box for easier delivery to rooms with difficult access. Compare specifications regarding foam density, cover materials, and mattress depth to match your existing bed frame and comfort preferences.

Manufactured in our UK workshop, every mattress in this category uses CertiPUR certified materials to ensure safety and environmental standards. With direct-from-factory availability, a 100-night home trial, and up to a 5-year warranty on select models, Mattress Depot provides a secure way to upgrade your sleep system.

The Ultimate Memory Foam Mattress Buying Guide

  • Pressure Relief: Memory foam is the best material for distributing body weight, making it ideal for those with joint or back pain.

Who Should Choose a Memory Foam Mattress?

  • Back Pain Sufferers: A memory foam mattress for back pain is highly effective because it fills the gap in the lumbar region, maintaining natural spinal alignment while cushioning the hips and shoulders.
  • Couples: If your partner is a restless sleeper, a memory foam mattress for couples with motion isolation ensures that energy isn't transferred across the bed, allowing both parties to sleep undisturbed.
  • Allergy Sufferers: The dense structure of our foam is naturally dust mite resistant and hypoallergenic, making it a safer choice for those with respiratory sensitivities.
  • Side Sleepers: Memory foam allows for the necessary "sink" at the shoulders and hips, preventing pressure points that cause morning stiffness.
  • Convenience Seekers: Our memory foam mattress in a box format is vacuum-packed and rolled, making it easy to maneuver through tight hallways and staircases upon delivery.

Materials & Construction

  • The Support Core: We use high-quality reflex foam or pocket springs to ensure the mattress doesn't sag, providing a stable base for the spine.
  • Safety & Compliance: All materials are BS7177 fire retardant and CertiPUR certified, meaning they are manufactured without ozone depleters or heavy metals.
  • The Cover: Our mattresses are finished with breathable, soft-touch fabrics designed to wick away moisture and keep the sleeping surface fresh.

How to Care for Your Memory Foam Mattress

  • Unboxing & Expansion: Once you receive your mattress in a box, carefully remove the packaging and allow it to expand for 24–48 hours in a well-ventilated room.
  • Initial Airing: It is normal for new foam to have a "new mattress smell." Air the room thoroughly during the first few days to allow any harmless scents to dissipate.
  • Rotation Schedule: To ensure even wear, rotate your mattress 180 degrees every few months. Most of our memory foam models are "non-turn," meaning you only need to rotate, not flip.
  • Cleaning Instructions: Use a soft damp cloth for spot cleaning. Avoid using harsh chemicals or saturating the foam with water, as this can damage the internal structure.
  • Use a Protector: We recommend using a breathable mattress protector to shield the foam from moisture and allergens, keeping your warranty valid and your bed hygienic.
