Why should you choose this mattress?
This mattress suits you if you want firm support without a hard surface. The 3cm memory foam layer contours to your shape, which means pressure points at the hips and shoulders get some relief even though the overall feel is firm. The 1500 pocket springs move independently, so a restless partner is less likely to disturb you, and SleepSoul says they prevent the roll-together effect. It arrives vacuum sealed in a box, begins taking shape within 2 hours and fully expands in 24. Yes, the lack of a stated trial is a drawback, but the 10-year guarantee offers some reassurance on durability, and the starting price is fair for a 31cm pillow-top hybrid.
Key features & layer details
Pillow-top layer
A soft pillow top of plush filling sits on the surface. This gives extra cushioning before you reach the firmer layers below.
Soft foam
A 5cm layer of soft foam adds a cushioned feel. It works with the pillow top to soften that firm overall rating.
Memory foam
This 3cm layer contours to your shape, which means pressure points are relieved as you settle in. It also acts as a transition layer, giving a controlled sink and minimising movement.
Hard foam
A 2cm hard foam layer distributes your weight consistently. It bridges the softer comfort layers and the springs beneath.
Pocket springs
1500 individual pocket springs conform to your body, supporting you where you need it most. Because each spring moves on its own, the design helps prevent the roll-together effect with a partner.
Base
A non-slip fabric base keeps the mattress steady on your bed frame. A small detail, but it stops the annoying gradual slide.

Best suited for?
Couples
The 1500 pocket springs move independently, so a restless partner is less likely to disturb you, and the design helps prevent the roll-together effect.
Back sleepers
A firm core does the supporting underneath, while the pillow top and 3cm memory foam layer add cushioning so the surface isn't hard.
Heavier sleepers
With 1500 pocket springs and a firm core below the comfort layers, this gives solid support, while the 31cm depth feels more substantial than many boxed mattresses.
Combination sleepers
Because the memory foam works as a transition layer giving a controlled sink, shifting position should feel steady, with the pillow top keeping the surface comfortable.
This is a firm mattress, so lightweight side sleepers may find it too unyielding despite the pillow top. It's also a poor fit if you want a risk-free trial: the brand's page mentions no trial period, so returns depend entirely on where you buy. Pillow tops can't be flipped either, only rotated.
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 SleepSoul Bliss 1500 firm or soft?
SleepSoul rates it as firm. The pillow top and 5cm of soft foam soften the surface feel, so you get cushioning on top of firm support rather than a hard, unforgiving sleep surface. Lighter side sleepers may still find it a little too firm.
How long does the SleepSoul Bliss 1500 take to expand?
It arrives vacuum sealed in a box, begins to take shape within 2 hours of unboxing, and is fully expanded within 24 hours.
Does the SleepSoul Bliss 1500 come with a guarantee?
Yes, SleepSoul provides a 10-year guarantee, which is reassuring on a mattress with an affordable starting price. No trial period is mentioned on the brand's page, so confirm returns terms with your chosen retailer before you buy.
What sizes does the SleepSoul Bliss 1500 come in?
It's available in UK Single, Small Double, Double, King and Super King.
How deep is the SleepSoul Bliss 1500 mattress?
It's 31cm deep, which is generous for a boxed mattress. Worth bearing in mind when buying fitted sheets, as shallower ones may not stretch over it comfortably.
