The product page lists the SleepSoul Comfort 800 as medium, so it should suit most sleeping positions without feeling hard. At 23cm deep it's slimmer than some hybrids, and it's a genuinely budget-friendly option. It comes in UK Single, Small Double, Double and King, with a 10-year SleepSoul warranty that needs registering on the brand's website within 30 days of purchase.

Why should you choose this mattress?
If you want pocket springs without a big spend, this is where the Comfort 800 makes its case. Each of the 800 springs moves independently, which means your movements are absorbed rather than transferred across the bed, useful if you share with a restless partner. The 2cm of high-density Reflex foam adds a touch of cushioning while keeping the feel supportive rather than sinky. It's hypoallergenic and fire resistant to BS7177: 2008 for home use, with a knitted cover on top. Buying through Mattress Online adds a 100-night trial, although that trial requires you to buy a mattress protector from them, and it's their offer rather than SleepSoul's.
Key features & layer details
Reflex Foam
A 2cm layer of high-density Reflex foam sits at the top, adapting to your shape for enhanced support. It's a thin comfort layer, so expect a supportive feel rather than deep cushioning.
Pocket Springs
Beneath the foam are 800 individual pocket springs, each moving independently for pressure relief and personalised support. Because the springs respond separately, you're less likely to feel a partner shifting about.

Best suited for?
Couples
Each of the 800 pocket springs moves independently, which means a restless partner's movements are absorbed rather than carried across the bed.
Budget buyers
Pocket springs usually cost more, but the copy calls this a budget-friendly option, so it suits anyone wanting springs without a big spend.
Back sleepers
The medium firm feel and thin 2cm Reflex foam layer give a supportive surface rather than a sinky one, which suits lying flat.
Allergy sufferers
The mattress is described as hypoallergenic, which makes it a sensible pick for anyone who wants to limit irritants in the bedroom.
Combination sleepers
A medium feel that suits most sleeping positions, with responsive individual springs, means changing position through the night should not feel awkward or hard.
With only 2cm of foam above the springs, this isn't the mattress for anyone wanting a plush, cushioned surface. Lightweight side sleepers may find it slightly firm on the shoulders and hips. Across owner reviews some people mention feeling springs at the edges, so if you sit or sleep near the edge, 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 SleepSoul Comfort 800 firm or medium?
The Mattress Online product page lists it as medium, although across owner reviews people describe the feel as medium-firm to firm. If you like a softer, more cushioned surface, this probably isn't the one for you.
Does the SleepSoul Comfort 800 have a trial period?
Mattress Online lists a 100-night trial, but this is the retailer's own offer rather than SleepSoul's, and it requires buying a mattress protector from them. If you purchase elsewhere, check that retailer's returns terms before you buy.
How long is the warranty on the SleepSoul Comfort 800?
SleepSoul offers a 10-year warranty, but you need to register on the SleepSoul website within 30 days of purchase for it to apply. It's an easy step to miss, so set a reminder once your mattress arrives.
How deep is the SleepSoul Comfort 800 mattress?
It's 23cm deep, which is on the slimmer side for a hybrid. Standard fitted sheets should fit without trouble, and the lower profile can suit divans or beds with shallow frames.
What sizes does the SleepSoul Comfort 800 come in?
It's available in UK Single, Small Double, Double and King. There's no Super King option listed, so couples wanting maximum width will need to look at a different model.
