Product Description

The Seymour Adjustable Mattress is a pocket spring and foam mattress from Land of Beds, made to work with adjustable bed bases. It's built around a 1000-count pocket spring unit topped with a layer of Air-Lite Comfort Foam, finished with a soft micro quilted cover, in a Medium Firm tension. The pocket springs respond independently to your body's contours while flexing with the base as it moves through its adjustable positions, giving pressure-relieving support whether the bed is flat or raised. Handmade in Great Britain and backed by a 5-year guarantee, it's designed as a standalone purchase for anyone who already owns a compatible adjustable base.


Who Is This Mattress For?

A Medium Firm pocket spring and foam mattress built specifically for use with adjustable bed bases, best suited to sleepers who want supportive comfort, effective pressure relief and the flexibility to change position through the night.

Medium Firm Feel - 4/6: A supportive feel with added stability. Ideal for people who change sleeping position during the night and need a balance of comfort and support.

Best for

  • Back sleepers - the Medium Firm tension helps keep your spine aligned and supported
  • Front sleepers - firm enough to help prevent your hips sinking too far
  • Combination sleepers - supportive and stable when changing position, and flexes with the base as it adjusts
  • People with back pain who need more support - the Medium Firm tension provides a supportive, stable feel
  • Couples - pocket springs move independently, reducing motion transfer between you and your partner
  • Sleepers up to 158kg (25st)

Not ideal for

  • Lightweight side sleepers who need more cushioning - the Medium Firm tension is firmer than a soft or soft-medium feel
  • Sleepers who prefer a soft, plush, sink-in feel

Inside This Mattress

1000 Pocket Spring System
What it is: Individually wrapped springs that respond independently to weight and movement across the mattress.
How it helps you sleep: Tailored support that follows your shape, with minimal motion transfer between sleeping partners, while flexing naturally with the adjustable base as it changes position.

Air-Lite Comfort Foam
What it is: A layer of comfort foam that conforms to the body's contours, sitting above the pocket spring unit.
How it helps you sleep: Provides personalised support and pressure relief, helping to alleviate discomfort at the hips, shoulders and lower back for better sleep posture.

Foam Encapsulated Edges
What it is: A high-density foam strip built into the edge of the mattress around the spring unit.
How it helps you sleep: Prevents the mattress from sagging at the border, extending its life and giving a more supportive sleeping area right to the edge.

Micro Quilted Cover
What it is: A soft, breathable and stretchy knitted top panel, quilted for extra cushioning.
How it helps you sleep: Provides a smooth, comfortable and snug sleeping surface with added cushioning from the moment you lie down.

How it Compares

Vs firmer mattresses: The Medium Firm tension and pocket spring and foam construction give a good balance of pressure relief and stability. If you're a combination sleeper who changes position often, or share a bed and want reduced motion transfer, this is likely the better choice. Firmer mattresses suit heavier sleepers or those who want a more rigid, supportive surface.

Vs softer mattresses: This mattress has more underlying support than a soft-tension option, while still offering a comfort layer of Air-Lite foam. Softer mattresses can feel more immediately plush but may not maintain the same spinal alignment as consistently, particularly for combination sleepers or heavier individuals.

Vs premium and luxury mattresses: This mattress shares the same pocket spring and foam construction principles found in higher-priced options in the range. The difference typically lies in the depth of the comfort layers and the spring count, rather than any compromise in quality, and it remains purpose-built to work with an adjustable base.


5 Year Guarantee

The Seymour Adjustable Mattress is backed by a 5-year guarantee against defects in materials and workmanship. Given the quality of the pocket spring and foam construction, this is a mattress built to work reliably with your adjustable base for years to come.
