Best for
Not ideal for
3700 Pocket Springs
What it is: A system of 3700 individually wrapped springs, each moving independently to respond to your body's shape and weight.
How it helps you sleep: Each spring settles back into place as you move, keeping support consistent across the whole mattress and reducing motion passed on to your partner.
Mini Comfort Springs
What it is: A secondary layer of smaller, individually pocketed springs positioned above the main spring system, offering greater spring density.
How it helps you sleep: Adds a finer level of pressure relief and weight distribution just beneath the comfort layers, helping reduce pressure points for a more restful, undisturbed sleep.
ActivFlex Spring Foam
What it is: An innovative comfort layer that combines the benefits of pocket springs and foam, contouring to your unique body shape.
How it helps you sleep: Unlike heat-sensitive foam, ActivFlex is pressure-sensitive, adjusting instantly to your movements for continuous support while minimising motion transfer. It's also fully recyclable at the end of its life.
Pillow Top Staycool Gel Layer
What it is: A plush Pillow Top layer infused with Staycool Gel, sitting above the supportive layers below.
How it helps you sleep: Adds a soft, cloud-like cushioning on entry while the gel helps manage moisture and regulate body temperature, relieving pressure points as it responds to your shape.
Staycool Gel Layer
What it is: A pressure-sensitive gel layer positioned beneath the Pillow Top.
How it helps you sleep: Helps manage moisture within the mattress, keeping you cool and comfortable, especially in warmer months.
Comfort & High-Density Support Layer
What it is: Supportive fibre layers positioned beneath the comfort layers, chosen for their rebound properties.
How it helps you sleep: Reinforces the mattress structure beneath the softer layers, helping the mattress keep its shape and supportive feel for longer.
Edge to Edge Foam Encapsulated Support
What it is: A high-density foam strip placed inside the edge of the mattress springs.
How it helps you sleep: Prevents the mattress from sagging at the edges, giving a longer life and a more supportive sleeping area right to the edge of the bed.
Quilted Soft Knit Fabric Cover
What it is: A soft knit fabric cover in 100% polyester, quilted for a smooth, cushioned finish.
How it helps you sleep: Gives the mattress a comfortable, luxurious surface to sleep on while adding a further layer of gentle cushioning.
Side Stitching
What it is: Reinforced stitching that ties the border fabric to the spring system along the mattress sides.
How it helps you sleep: Supports the mattress walls and extends the usable sleeping area closer to the edge.
Flag-Stitched Handles
What it is: Handles fitted to both sides of the mattress.
How it helps you sleep: Makes it easier to position and rotate the mattress when needed.

Vs firmer mattresses: The ActivFlex Spring Foam and gel-infused Pillow Top give this mattress noticeably more cushioning at the shoulders and entry point than a firmer alternative. If you like a supportive feel that still has some give, this is likely the better fit. Firmer mattresses suit heavier sleepers or those who want a more rigid, minimal-sink surface.
Vs softer mattresses: This mattress has more underlying spring support than a softer mattress, thanks to the combined 3700 pocket and mini comfort springs. Softer mattresses can feel more immediately plush but may not hold spinal alignment as consistently for back and front sleepers, or for combination sleepers changing position through the night.
Vs standard memory foam mattresses: The Staycool Gel layers here are designed to sleep noticeably cooler than traditional memory foam, which can retain body heat. ActivFlex Spring Foam also responds instantly to movement rather than slowly like heat-sensitive foam, making this a strong choice for hot sleepers or those who move around during the night.
The ActivFlex Ultra is backed by Sleepeezee's 10-year manufacturer's guarantee against defects in materials and workmanship. Given the quality of the spring and foam construction, this is a mattress built to last - the guarantee reflects that.

Gave 3 star for quality because of the pillow top on both ends is shorter then the mattress, so it slopes down, and 1 star for value, as i paid £1050, but i looked again few weeks later and it went down to £799. It is comfortable but its very cold to get into in the winter, i asked sleepeezee if I can use electric blanket on it with it having foam springs, they said yes on low and not for long, but if for any reason the blanket causes the foam springs to warp they won't cover it under warranty. So if you dont mind paying over the odds, getting into a cold bed in winter and dont mind your pillow slipping down your headboard. Then its for you. Be ok in summer. If I had known about the electric blanket issue, I would of returned it with my sleep trial, but by the time I found out it was too late. My advice is, DONT by your new mattress online, easy said then done I know, but when your paying over £1000 its not wise, and 60 sleep trial isnt long enough, like i found out.

The Sleepeezee ActivFlex Ultra Mattress is superb! It provides excellent support without being too firm, and it has made a noticeable difference in my sleep quality. I wake up feeling rested and without any aches or pains. The ActivFlex technology really works wonders for comfort and breathability. This mattress is worth every penny, and I’d recommend it to anyone in need of a better night’s sleep!
read moreYes, this mattress is suitable for a slatted base as long as your slats are in good condition and no further apart than 7.5cm.
This is an easycare mattress, which means you do not need to turn the mattress over, however you should rotate from head to toe on a regular basis to ensure even use.
This mattress is 33cm deep.
Gel is a synthetic material that is very similar to memory foam that offers a cooler sleeping surface and has a softer feel. They are both good at pressure relief and reducing disturbance from a sleeping partner.
This mattress uses a pocket spring system that is a series of individual steel springs encased in fabric pockets that are designed to contour to body shape and weight to provide comfort and support.
