The Sleepeezee Jessica 800 Pocket Support sits at 27cm deep and Sleepeezee describes it as medium to firm, so it suits back and combination sleepers who like a supportive surface, although lightweight side sleepers may find it a little too firm. It's good value for a handcrafted UK mattress from a National Bed Federation approved brand. It's hypoallergenic and vegan-friendly too.

Why should you choose this mattress?
The appeal here is straightforward: pocket sprung support at a reasonable price. The 800 individual springs move independently, which means less motion transfer from a restless partner and pressure relief where your body needs it. Above the springs, a gel foam layer and Sleepeezee's Platinum Breathable layer work on temperature, so if you tend to sleep warm you should feel a slightly fresher surface than standard memory foam gives. It's handcrafted in the UK and carries hypoallergenic and vegan-friendly credentials. Buy through Mattress Online and you get a 100-night trial and a 10-year guarantee under their terms, which takes some of the risk out of the decision.
Key features & layer details
Platinum Breathable™ layer
A temperature-regulating top layer that helps your body stay at a comfortable temperature through the night. In practice, that means less waking up too hot or too cold.
Gel Foam
A breathable foam that sleeps cooler than traditional memory foam, which means you get cushioning for aches and pains without the trapped heat. It gives the sleep surface a fresher feel.
Pocket Springs
800 individual pocket springs mould to your body shape, relieving pressure and delivering that medium to firm support. Because each spring moves independently, you'll feel less disturbance when a partner shifts position.

Best suited for?
Back sleepers
The medium to firm feel gives a supportive surface that keeps you level on your back, with the pocket springs easing pressure where your body meets the bed.
Combination sleepers
Medium to firm support and 800 independent pocket springs let you change position through the night without sinking in or feeling stuck.
Couples
Each of the 800 pocket springs moves on its own, which means you'll feel less disturbance when your partner shifts or gets up.
Warm sleepers
A gel foam layer and the Platinum Breathable layer work on temperature, so the surface should feel fresher than standard memory foam.
Allergy sufferers
The copy describes this mattress as hypoallergenic, which makes it a sensible pick if you want a bed that avoids common irritants.
If you prefer a soft, sink-in feel, this medium to firm mattress will likely feel too solid, and some owners do report it feels firmer than expected. Sizes are limited too: there's no standard UK Double or King, so you may need to look elsewhere for those.
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 Jessica 800 mattress?
Sleepeezee describes it as medium to firm. That suits back sleepers and heavier side sleepers well, although lightweight side sleepers may find it a little too firm on the shoulders and hips. Some owner reviews mention it feeling firmer than expected, so factor that in if you like a softer surface.
Does the Sleepeezee Jessica 800 come with a trial period?
Mattress Online lists a 100-night trial with this mattress, along with a 10-year guarantee. These are the retailer's own terms rather than a manufacturer-wide offer, so if you buy elsewhere, check that retailer's trial and returns policy before ordering.
Is the Sleepeezee Jessica 800 good for hot sleepers?
It should help. The gel foam layer is more breathable than traditional memory foam, and the Platinum Breathable top layer is designed to regulate temperature, which means a cooler surface than an all-foam mattress typically offers. It won't feel icy, but it shouldn't trap heat either.
What sizes does the Sleepeezee Jessica 800 come in?
It's available in UK Single, UK Small Double and UK Super King. That's a limited range: there's no standard Double or King listed, which rules it out for a fair number of buyers.
How is the Sleepeezee Jessica 800 delivered?
Mattress Online offers free delivery to most locations with a two-hour time slot and a call on delivery day. You can choose next day delivery on weekdays, pick a weekday up to 60 days ahead, or opt for weekend delivery. Room delivery and old mattress recycling are available for an extra charge.
