Why should you choose this mattress?
This is a sensible pick if you want a medium feel with a bit of cushioning on top. The pillow top and soft polyester layer add give at the surface, while the Staycool Gel foam has an open-cell structure, which should help the mattress feel cooler. Beneath that, mini comfort springs sit over traditional pocket springs, so the comfort and support are handled by separate layers. A fully encapsulated foam border runs edge to edge around the spring unit. It's single-sided and no-turn, so there's no flipping, and it has flag-stitched turning handles. It suits most sleepers, although you may want something firmer if you like a hard feel.
Key features & layer details
Soft knitted cover
A soft knitted cover finishes the top of the mattress. It gives you a gentle surface to lie on.
Soft polyester comfort layer
A soft polyester filling sits under the cover. It adds cushioning at the surface, which is part of the pillow top feel.
Staycool Gel
A cooling comfort foam with an open-cell structure. It's there to help the mattress feel cooler while still cushioning you.
ActivFlex spring foam
A profiled, responsive support foam layer. It adds support under the comfort layers, so you aren't sinking straight through.
1400 mini comfort springs
Mini pocket springs sit in the comfort layer. They respond to your body in smaller areas, which adds to the cushioned feel.
1200 traditional pocketed springs
Traditional pocket springs form the core of the mattress. They give the main support underneath you.
Fully encapsulated spring unit
The spring unit sits inside a fully encapsulated foam border. That gives the edges a more stable feel.
Foundation support pad
A foundation pad sits at the base as the foundation for the layers above. It separates the springs from your bed base.

Best suited for?
Warm sleepers
The Staycool Gel foam layer has an open-cell structure, which should help the mattress feel cooler while you still get cushioning on top.
Side sleepers
A pillow top, soft polyester layer and 1400 mini comfort springs add give at the surface, so the mattress cushions your body without feeling soft.
Couples
Separate mini comfort springs over traditional pocket springs, plus a fully encapsulated foam border, give a stable edge and the choice of Double or Super King.
Combination sleepers
Responsive ActivFlex spring foam sits under the comfort layers, so you aren't sinking straight through when you change position on a medium feel.
If you prefer sleeping on a firm mattress, this might not be the best choice. It's rated medium, and the pillow top adds cushioning that some back and front sleepers may find too forgiving. It's also single-sided, so you can't flip it. You can only rotate it, which matters if you like to turn a mattress over.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the Sleepeezee ActivFlex Response 2600 Pocket Pillow Top?
It's rated medium, with a pillow top that adds some cushioning at the surface. That suits most sleepers well, although anyone who wants a properly firm feel may find it too soft.
What sizes does the Sleepeezee ActivFlex Response 2600 Pocket Pillow Top come in?
It comes in UK Single (90x190cm), Small Double (120x190cm), Double (135x190cm) and Super King (180x200cm). If you need a different size, check the other options before you buy.
How deep is the Sleepeezee ActivFlex Response 2600 Pocket Pillow Top?
It's 27cm deep. That's a fairly tall mattress, so check that your bed frame and any fitted sheets can handle the extra height.
Can you flip the Sleepeezee ActivFlex Response 2600 Pocket Pillow Top?
No. It's single-sided and no-turn, with flag-stitched turning handles to help you rotate it. You can turn it end to end, but the pillow top means it stays the same way up.
Is the Sleepeezee ActivFlex Response 2600 Pocket Pillow Top good for hot sleepers?
It has a Staycool Gel foam layer with an open-cell structure, built to help it feel cooler. That should help if you sleep warm, but a pillow top still adds cushioning layers above it.
