Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw is honest 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. At £235 upwards 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 & what's inside
- 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.

Who's it NOT for?
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.

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, priced from £235 to £369 depending on size. There's no Super King option, so couples wanting the largest size will need to look at other models.
