Why should you choose this mattress?
Choose the Balance 800 if you want a straightforward hybrid at a genuinely low price. The pocket springs run edge to edge and react independently, which means less roll-together if you share the bed, while the memory foam layer responds to body temperature to spread your weight and ease pressure points. It carries a 10-year warranty from SleepSoul, though you'll need to register on their website within 30 days, and it conforms to BS7177: 2008 fire resistance standards for home use. Yes, the 2cm foam layer is thin compared with pricier hybrids, but at an affordable starting price the balance of comfort, support and value is hard to argue with.
Key features & layer details
Memory Foam
A 2cm top layer that responds to body temperature, which means it softens where you press into it and spreads your weight evenly for soothing pressure relief. It's a slim layer, so expect a gentle cushion rather than a deep sink-in feel.
Pocket Springs
800 pocket springs run edge to edge and react independently to your movements, giving personalised support with no roll-together. That independence means you're less likely to be disturbed when a partner shifts in the night.

Best suited for?
Couples
Independent pocket springs run edge to edge, which means you're less likely to feel a partner shifting in the night and there's little roll-together.
Budget buyers
The copy calls it affordable and a genuinely low price, with a 10-year warranty and a 100-night trial adding reassurance for the money.
Back sleepers
A medium firm feel with 800 pocket springs gives steady support, while the thin memory foam layer adds a gentle cushion without sinking you in too far.
Combination sleepers
Because the memory foam layer is only 2cm thick, you can change position without feeling stuck in, and the springs react independently as you move.
Heavier sleepers
Springs running edge to edge, which means support stays consistent across the surface, and the firmer feel owners report should resist sinking too deeply.
If you love a deep, cradling memory foam feel, the slim 2cm comfort layer here won't deliver it. Some owners also report it feels firmer than the medium label suggests, so lightweight side sleepers may find it a little unforgiving. And there's no Super King option in the listed sizes.
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 Balance 800 firm or medium?
SleepSoul describes it as medium, although some owner reviews mention it feels firmer than expected. If you're a lightweight side sleeper, it may feel slightly firmer than a typical medium; back and combination sleepers should find it comfortable.
How many springs does the SleepSoul Balance 800 have?
It contains 800 pocket springs arranged edge to edge. Each spring moves independently, which means support adjusts to your body shape and movement on one side of the bed is less likely to disturb the other.
Does the SleepSoul Balance 800 come with a trial period?
Mattress Online lists a 100-night trial with this mattress, but that's the retailer's own offer rather than a SleepSoul guarantee. If you buy elsewhere, check that retailer's returns terms before ordering.
What warranty does the SleepSoul Balance 800 have?
It comes with a 10-year warranty from SleepSoul, but you need to register your mattress on the SleepSoul website within 30 days of purchase for it to apply. Set a reminder when it arrives so you don't miss the window.
How deep is the SleepSoul Balance 800 mattress?
It's 23cm deep, made up of a 2cm memory foam top over the pocket spring unit, with a knitted cover. Most standard fitted sheets will accommodate this depth comfortably.
