Why should you choose this mattress?
Choose the Wish 3000 if you want the springy, supportive feel of pocket springs softened by a genuinely plush surface. The pillow top adds a layer of cushioned fillings on top, so you sink into comfort before the springs take over. Below that, cool gel memory foam relieves pressure and handles heat better than standard memory foam, useful if you tend to sleep a little warm. At 30cm deep and medium firm, it should suit back and combination sleepers well. Sizes range from UK Single to Super King, with EU sizes available too, which is handy if you have a continental bed frame. MattressNextDay lists free next day delivery.
Key features & layer details
Pillow Top
An extra layer of plush fillings sewn onto the surface, which means a softer, more cushioned first impression when you lie down. It gives the medium firm core a gentler feel on pressure points like hips and shoulders.
Cool Gel Memory Foam
This foam contours to your body for pressure relief and support, while the gel helps regulate body temperature better than standard memory foam. In practice, you get the hug of memory foam with less of the heat build-up.
Pocket Springs
Each spring sits in its own fabric pocket and moves independently, which means the mattress responds to your body shape rather than pushing back as one unit. That independence also helps reduce disturbance when a partner moves.

Best suited for?
Back sleepers
The medium firm feel and 30cm depth give steady support under the spine, while the pillow top keeps the surface comfortable.
Combination sleepers
Independent pocket springs respond to your body as you change position, so the medium firm feel stays supportive on your back or side.
Warm sleepers
Cool gel memory foam helps regulate body temperature better than standard memory foam, giving you the contouring hug with less heat build-up.
Couples
Each spring sits in its own fabric pocket and moves independently, which helps reduce the disturbance you feel when a partner moves.
Budget buyers
It is described as good value for a hybrid with a pillow top, so you get springs, gel foam and a plush surface together.
If you prefer a very firm, flat sleeping surface, the plush pillow top may feel too soft on top. Equally, anyone wanting an all-foam feel should look elsewhere, as the pocket springs give this a bouncier response. Note the pillow top cannot be flipped away if you change your mind.
Save on an earlier or ex-display model

FAQ's
How firm is the SleepSoul Wish 3000 mattress?
It's listed as medium firm, which suits most back and combination sleepers. The pillow top softens the surface feel, so it lies a little gentler than the rating suggests, although lightweight side sleepers may still find it slightly firm.
Does the SleepSoul Wish 3000 sleep cool?
It uses cool gel memory foam, which regulates body temperature better than standard memory foam, and pocket springs allow airflow through the core. If you're a hot sleeper it's a sensible pick, though no mattress can promise you'll never overheat.
What warranty comes with the SleepSoul Wish 3000?
The MattressNextDay listing states a SleepSoul 10 year warranty. As this comes from a retailer page rather than the brand's own site, it's worth confirming the terms with your chosen retailer before you buy.
Is there a trial period with the SleepSoul Wish 3000?
No trial period is mentioned on the MattressNextDay listing we sourced. Check directly with the retailer you buy from, as sleep trials and returns policies are set by the seller.
How deep is the SleepSoul Wish 3000 mattress?
It measures 30cm deep, which is generous and reflects the added pillow top layer. Check your fitted sheets will stretch to a deeper mattress, as standard sheets can struggle at this depth.
