The Sleepeezee ActivFlex Ultra is a medium-feel hybrid mattress made exclusively for Land of Beds. It's built around 3700 traditional and mini comfort pocket springs paired with ActivFlex Spring Foam, and finished with a gel-infused Pillow Top and Staycool Gel layer. The result is a supportive, pressure-relieving feel that also helps regulate temperature through the night. This clearance listing offers the Double size at a reduced price - the mattress itself is genuine, current Sleepeezee stock, not a returned or display item, and comes with the full 10-year manufacturer's guarantee.
A medium-feel hybrid mattress from Sleepeezee, made exclusively for Land of Beds, best suited to sleepers who want balanced support, effective temperature regulation and minimal partner disturbance.
Medium Feel - 3/6: The Goldilocks option - not too firm, not too soft. Medium is the most versatile firmness level, balancing comfort and support in a way that suits most sleeper types.

Worth knowing:
3700 Pocket Springs
What it is: A system of 3700 individually wrapped springs that each move independently in response to body weight and shape.
How it helps you sleep: Each spring resets as you shift position, keeping support even across the mattress and limiting how much movement carries over to a sleeping partner.
Mini Comfort Springs
What it is: A second, finer layer of smaller pocket springs sitting above the main spring system.
How it helps you sleep: Adds an extra layer of targeted pressure relief just beneath the comfort layers, smoothing out pressure points for a more settled night's sleep.
ActivFlex Spring Foam
What it is: A comfort layer that blends the properties of pocket springs and foam, contouring to the body's shape.
How it helps you sleep: Reacts to pressure rather than heat, so it adjusts to movement instantly rather than slowly like traditional memory foam, while still limiting motion transfer. It's also fully recyclable at the end of its life.
Gel-Infused Pillow Top
What it is: A plush upper comfort layer infused with cooling gel.
How it helps you sleep: Provides soft, immediate cushioning on lying down, while the gel content helps manage moisture and body heat.
Staycool Gel Layer
What it is: A pressure-responsive gel layer positioned beneath the Pillow Top.
How it helps you sleep: Helps draw moisture away from the sleep surface, keeping the mattress cooler and more comfortable, particularly in warmer weather.
Comfort & High-Density Support Layer
What it is: Supportive fibre layers positioned beneath the upper comfort layers, chosen for their rebound properties.
How it helps you sleep: Reinforces the structure underneath the softer layers, helping the mattress hold its shape and supportive feel over time.
Edge-to-Edge Foam Encapsulated Support
What it is: A firmer foam border built into the edge of the spring system.
How it helps you sleep: Stops the mattress sagging at the edges, extending its usable sleeping area right to the perimeter and helping it last longer.
Quilted Soft Knit Cover
What it is: A soft knit fabric cover, 100% polyester, quilted for a smooth, cushioned finish.
How it helps you sleep: Adds a comfortable, plush surface to sleep directly on top of, with a further layer of gentle padding.
Side Stitching
What it is: Reinforced stitching connecting the border fabric to the spring system along the mattress sides.
How it helps you sleep: Strengthens the mattress walls and extends the usable sleeping surface closer to the edge of the bed.
Flag-Stitched Handles
What it is: Handles fitted to both long sides of the mattress.
How it helps you sleep: Makes it easier to position, rotate or move the mattress when needed.

Vs firmer mattresses: The ActivFlex Spring Foam and gel-infused Pillow Top give this mattress noticeably more pressure relief at the shoulders and hips than a firmer alternative. If you sleep on your side or share a bed, 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 structural support underneath the comfort layers, thanks to the combined 3700 pocket and mini comfort springs. Softer mattresses can feel more immediately plush but may not maintain spinal alignment as consistently - especially for combination sleepers or couples with different body weights.
Vs premium and luxury mattresses: This mattress shares the same pocket spring technology and gel-cooling comfort layers found in higher-priced options. The difference is typically in the depth of the comfort layers and the number of fillings, rather than any compromise in quality or construction.
The ActivFlex Ultra comes with Sleepeezee's 10-year manufacturer's guarantee against defects in materials and workmanship. This is the full, standard guarantee - it applies in exactly the same way to this clearance Double size as it does to the regular range.
