Product Description

The Sleepeezee Gel 4000 is a handcrafted pocket spring pillow top mattress from Sleepeezee, a Royal Warrant holder that has been making beds in Great Britain since 1924. It's built around 1,000 pocket springs and 3,000 mini comfort springs, topped with two individual layers of Staycool Gel for pressure-relieving, temperature-regulating comfort. The result is a medium firm mattress that suits sleepers who change position through the night, backed by a free 10-year guarantee and a 60 night comfort trial.


Who Is This Mattress For?

The Sleepeezee Gel 4000 is a handcrafted pocket spring pillow top mattress best suited to sleepers who want medium firm (4/6) support, effective cooling and minimal partner disturbance.

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 keeps your spine supported without feeling too soft
  • Front sleepers - firm enough underneath to stop your hips sinking too far
  • Combination sleepers - responsive pocket and mini comfort springs adjust as you move through the night
  • Hot sleepers - two layers of Staycool Gel channel away excess heat and manage moisture
  • Couples - 4,000 individually pocketed springs work independently to reduce partner disturbance
  • Sleepers up to 114kg (18st) per side

Not ideal for

  • Sleepers who prefer a very soft, sink-in feel - the Gel 4000 is a medium firm (4/6) mattress. See our soft or soft medium range for a plusher feel.
  • Lightweight side sleepers who want deep cushioning at the shoulders and hips.

Inside This Mattress

1,000 Pocket Springs What it is: Individually pocketed springs, each working independently, with the upper part shaping to body contours while the lower part absorbs changes in weight distribution. How it helps you sleep: Provides individual, personalised support whatever your shape or sleeping position, and the springs work independently to avoid rolling together with your partner.

3,000 Mini Comfort Springs What it is: Smaller, individually pocketed springs layered above the main spring unit for targeted pressure relief. How it helps you sleep: Adjusts to your body's contours for improved weight distribution, reducing motion transfer and promoting better spinal alignment.

Double Layer of Staycool Gel What it is: Two individual layers of pressure-sensitive gel positioned within the pillow top comfort layers. How it helps you sleep: Responds immediately to your body shape for pressure-relieving support, while channelling away excess body heat so you don't feel too hot in warmer months.

Comfort and High Density Support Layer What it is: Supportive fibre layers beneath the gel comfort layers, featuring rebound properties. How it helps you sleep: Adds excellent levels of comfort while the rebound properties give enhanced underlying support, helping the mattress maintain its shape over time.

Pillow Top What it is: An extra layer of cushioning containing polyester and Staycool Gel, sewn on top of the mattress as if topped with a pillow. How it helps you sleep: Increases softness and comfort at the sleep surface, easing pressure points while the gel keeps the extra cushioning breathable.

Quilted Soft Knit Fabric Cover What it is: A soft knit cover upholstered over the mattress surface for a sumptuous finish. How it helps you sleep: Gives the mattress an enhanced, luxurious feel next to the skin while supporting the comfort layers beneath.

Side Stitching What it is: Stitching applied along the sides of the mattress that ties the border fabric to the spring system. How it helps you sleep: Extends the sleeping area to the mattress edge by supporting the mattress walls, giving you more usable sleeping surface.

Flag-Stitched Handles What it is: Handles sewn onto both sides of the mattress using a flag-stitch method. How it helps you sleep: Makes it easy to reposition and rotate the mattress, helping you maintain it properly for long-lasting comfort.

Chrome Air Vents What it is: Chrome-finished ventilation eyelets set into the sides of the mattress. How it helps you sleep: Allows good air circulation through the mattress, helping regulate temperature and keep it fresh.

How it Compares

Vs firmer mattresses: The Gel 4000's gel-infused pillow top gives noticeably more give at the shoulders and hips than a firmer feel, while the pocket and mini comfort springs still keep you well supported. If you move between sleeping positions through the night, this is likely the more comfortable choice. Firmer mattresses suit heavier sleepers or those who prefer a more rigid, unyielding surface.

Vs softer mattresses: This mattress has considerably more structural support beneath its comfort layers than a soft mattress. Soft mattresses can feel immediately plusher, but may not maintain spinal alignment as consistently for back and front sleepers, or for combination sleepers who shift position often.

Vs premium and luxury mattresses: The Gel 4000 shares the same pocket spring technology and pillow top construction found in higher-priced ranges. The difference is typically in the depth and range of natural fillings used and the level of hand-finishing, rather than any compromise in the quality of support.


10 Year Guarantee

The Sleepeezee Gel 4000 is backed by Sleepeezee's free 10-year manufacturer's guarantee against defects in materials and workmanship. Given the quality of the spring system and gel comfort layers, this is a mattress built to perform night after night - the guarantee reflects that.


Awards & Accreditations

Royal Warrant Holder - Sleepeezee has been appointed by Royal Warrant, a mark of craftsmanship and quality that has to be earned and maintained.

    Very impressed with this mattress so far. It’s supportive but still soft on top, and the gel layer keeps it feeling cool through the night. Great option if you want comfort without overheating.
