Why Choose a Sealy Mattress?

Sealy has been a global leader in sleep innovation for over 130 years, trusted in more than 60 countries. Every mattress is designed with three key goals:

  • Targeted support - keeps your spine aligned and cushions your body where it matters most.
  • Comfort for all sleepers - innovative foams and fabrics adapt to different body types and sleep positions.
  • Long-lasting durability - built to perform night after night.

Many Sealy mattresses are also developed with guidance from orthopaedic specialists, ensuring the support your body needs for a healthy, restorative sleep.

Sealy Mattress Collections

Sealy makes it easy to find the mattress that suits you, with three main collections:

Essentials Collection

Open spring (Bonnell) mattresses that offer firm, reliable support at a great price. Ideal if you prefer a simple, no-frills mattress that lasts.

Performance Collection

Individually pocketed springs reduce partner disturbance while providing even body support. A popular choice for couples or anyone who wants a balance of comfort and stability.

Premium Collection - Sealy Posturepedic

Developed with orthopaedic guidance, these mattresses give advanced spinal alignment and pressure relief. The AlignSupport spring system adapts to your weight and sleeping position, while cushioned foams support sensitive areas like hips and shoulders. Available in Elevate and Elevate Ultra models for the ultimate in restorative sleep.

For more guidance, read our Sealy Posturepedic Buying Guide before choosing your perfect mattress.

Match Your Sealy Mattress to Your Sleep Style

The right mattress depends on how you sleep:

  • Back sleepers - firmer surfaces to support spinal alignment.
  • Side sleepers - softer layers to relieve pressure on shoulders and hips.
  • Front sleepers - balanced support to reduce strain on lower back and pelvis.

Not sure which is right for you? Our Sealy trained mattress experts are happy to guide you.

Sealy mattresses are designed for long-term comfort and wellbeing:

  • Durable springs and coils - hold their shape for years.

Questions & Answers

  • What sizes do Sealy mattresses come in?

    From single to super king, Sealy mattresses are available in all standard UK sizes. Whether it’s for a child’s room, guest room, or master bedroom, there’s a size to fit.

  • Can I use a new Sealy mattress on an old base?

    Yes, if your base is in good condition and supports the mattress evenly. For heavier or premium mattresses, it’s best to ensure your base can handle the weight, or consider a new base for optimal comfort. We can advise.

  • Does mattress depth matter?

    Absolutely. Sealy Posturepedic mattresses come in a range of depths, which can affect support and comfort depending on your weight and sleep style. Deeper mattresses generally provide more cushioning, while shallower mattresses suit lighter sleepers.

  • Will a Sealy mattress help with back pain?

    Yes. Sealy Posturepedic mattresses are designed with orthopaedic guidance to support spinal alignment, reduce pressure points, and help improve sleep quality for those with back concerns.

  • How long will a Sealy mattress last?

    With proper care, most Sealy mattresses provide 7–10 years of comfort and support. Choosing the right mattress for your body type and sleep habits helps maximise lifespan.
