The brand describes the Jay-Be 1000 e-Pocket as medium, so expect a supportive feel with a modest amount of give. It comes in UK Single, Small Double, Double and King sizes, and it's genuinely affordable for a pocket sprung, UK-handcrafted mattress. It's hypoallergenic and comes with a 5-year manufacturer guarantee.

Why should you choose this mattress?
The main draw is good value. You get 1,000 pocket springs, each moving independently, which means your partner's tossing and turning is less likely to travel across the bed, plus breathable fibre fillings and a knitted cover designed to keep air moving. If you sleep warm, that all-fibre, no-foam build is a quieter advantage than any marketing line. It's handcrafted in the UK, from a National Bed Federation approved brand, and the fillings are hypoallergenic, useful if dust sensitivities bother you. It sits at the budget end, and the comfort layers are simpler than pricier hybrids, but for a spare room, a teenager or a first mattress it makes a strong case.
Key features & layer details
Knitted cover
A soft knitted cover that adds a cosy, slightly warm surface feel. The knit structure is designed to let air pass through, which helps the mattress breathe overnight.
Soft White Fibres
Soft synthetic e-Fibre fillings that give the top of the mattress its cushioned feel. They're designed to be resilient, holding their shape rather than flattening quickly.
3D spacer
A spacer layer that improves airflow through the mattress. In practice, that means less heat building up around you as you sleep.
Pocket Springs
Springs sit in individual cloth pockets, so each one responds to your body independently. That gives more tailored support along your spine and reduces the ripple effect when someone else moves.

Best suited for?
Couples
The 1,000 pocket springs each move independently, which means one partner's tossing and turning is less likely to travel across the bed to the other.
Warm sleepers
An all-fibre, no-foam build with a knitted cover and a 3D spacer layer lets air move through, so less heat builds up overnight.
Allergy sufferers
Hypoallergenic fillings make this a sensible pick if dust sensitivities bother you, and the 100 night trial gives time to check it suits you.
Budget buyers
The copy calls it good value for a UK-handcrafted pocket sprung mattress, with a 5 year guarantee included, so you get solid build without a high outlay.
Teenagers
A medium firm, springy feel with simple, resilient fibre fillings makes it a practical choice for a teenager's bed or a first mattress.
If you love a deep, sink-in memory foam feel, this isn't it: the fibre-and-spring build is springier and sits you more on top of the mattress. At 21cm it's also slimmer than many mattresses, so heavier sleepers wanting deep cushioning, or anyone expecting a plush pillow-top, should look elsewhere.
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
Is the Jay-Be 1000 e-Pocket mattress firm or medium?
Jay-Be describes it as medium, so expect a balanced feel with some give at the surface and firmer support from the 1,000 pocket springs beneath. Some retailer catalogues list it as medium firm, but the product page wording is medium.
Does the Jay-Be 1000 e-Pocket come with a trial period?
Mattress Online lists a 100-night trial with this mattress. That's the retailer's own offer rather than a Jay-Be policy, so if you buy elsewhere, check that seller's returns terms before ordering.
How long is the guarantee on the Jay-Be 1000 e-Pocket?
It comes with a 5-year manufacturer guarantee. That covers you for a reasonable stretch, though some pricier mattresses do offer longer, so weigh it against the low purchase price.
Is the Jay-Be 1000 e-Pocket good for hot sleepers?
It should suit you reasonably well. There's no memory foam to trap heat, the fillings are breathable e-Fibre, and a 3D spacer layer plus the knitted cover are both designed to keep air moving through the mattress.
What sizes does the Jay-Be 1000 e-Pocket come in?
It's available in UK Single, Small Double, Double and King. There's no Super King option, so couples wanting the largest size will need to look at other models.
