Quick verdict
This is a size-first shortlist for a standard UK double mattress, usually 135cm x 190cm (4'6" x 6'3"). The best starting point is whether you want a Pocket Sprung feel or a Hybrid build: Aspire Pocket+ 1000 Tufted Mattress starts from £205, while Bodyshape Gel 2000 Pocket Hybrid Mattress starts from £335. The shortlist is practical rather than definitive, so compare room fit, bed-frame compatibility, firmness and current price before deciding which option is worth a closer look.
Top picks to compare
Start with Aspire Pocket+ 1000 Tufted Mattress (£205-£305), Bodyshape Boost 1000 Pocket Memory Mattress (£299-£589), Bodyshape Gel 2000 Pocket Hybrid Mattress (£335-£605) because they give you a focused set of current retailer options to compare. The visible price range is £205-£815, so check whether the extra spend buys a useful specification difference rather than only a different brand or finish. The shortlist includes Aspire, Bodyshape, Horizon, which helps you compare familiar brands against specification, delivery and value.

What the research says about double beds
A double-bed comparison only works if the mattress size, frame and room space all line up. UK size guides consistently describe a double as 135cm x 190cm (4'6" x 6'3"), so it is worth checking the exact frame label before you buy, especially if you are replacing a mattress on an older base. On this shortlist, Aspire Pocket+ 1000 Tufted Mattress starts from £205, Bodyshape Boost 1000 Pocket Memory Mattress starts from £299 and Bodyshape Gel 2000 Pocket Hybrid Mattress starts from £335, which makes the page useful for comparing fit and construction as well as price. The shortlist is retailer-curated and public review depth is thin in the available data, so treat these mattresses as compare-and-choose options rather than a reputation-led ranking.
Trade-offs to compare before buying
The clearest trade-off here is support feel versus comfort style. Pocket Sprung models such as Aspire Pocket+ 1000 Tufted Mattress and Bodyshape Boost 1000 Pocket Memory Mattress sit against the Hybrid Bodyshape Gel 2000 Pocket Hybrid Mattress, so shoppers can compare a spring-led feel with a hybrid build that is positioned around more breathable comfort. It is also worth checking the 100-night comfort trial, free delivery to most locations and old mattress removal wording on the retailer page, because those extras can affect real-world value as much as a small price gap. Guarantee length varies too: Aspire and Bodyshape Gel 2000 show 5-year guarantees, while Bodyshape Boost 1000 Pocket Memory Mattress shows a 1-year guarantee.
Why these five mattresses belong together
The shortlist brings together five mattresses from three brands: Aspire, Bodyshape and Horizon. That mix is useful because it lets you compare two main construction types, Pocket Sprung and Hybrid, across different price points without jumping between unrelated product families. It is still not a definitive best-in-class list, though, because the selection reflects a retailer-curated set with limited independent review depth and size-dependent prices that can vary from one variant to another.
Shortlist benchmark at a glance
The benchmark set runs from £205 to £335 for the current comparison range, but individual product pages show wider size-dependent spans, reaching up to £815 on Horizon Juno 5000 Pocket Memory Mattress. Aspire Pocket+ 1000 Tufted Mattress is the entry point at £205-£305, Bodyshape Boost 1000 Pocket Memory Mattress sits at £299-£589, Bodyshape Ultra Ortho 1500 Pocket Mattress is marked Firm at £328-£577, Bodyshape Gel 2000 Pocket Hybrid Mattress is £335-£605, and Horizon Juno 5000 Pocket Memory Mattress stretches widest at £310-£815. The wider spread matters because it can reflect size choice, not just a simple quality jump.
How to choose the right one for your double bed
Choose Aspire Pocket+ 1000 Tufted Mattress if you want the lowest entry price in the shortlist and a straightforward Pocket Sprung option for a standard double frame. Choose Bodyshape Ultra Ortho 1500 Pocket Mattress if you are leaning toward a firmer feel, since Firm is the clearest visible secondary attribute in the set. Choose Bodyshape Gel 2000 Pocket Hybrid Mattress if you want the hybrid format, especially if you value a construction that is positioned around more breathable comfort, while Horizon Juno 5000 Pocket Memory Mattress is the one to compare carefully if you want a higher ceiling on size-dependent pricing and a broader spread of variants. In every case, check frame compatibility and mattress depth before ordering, because depth can affect bedding fit and whether the mattress sits neatly on your base.
Where the value looks strongest
Value here is not just about the lowest price; it is about what each mattress adds for the money and how much confidence the retailer terms give you. All listed mattresses show a 100-night comfort trial, free delivery to most locations and an old mattress removal service mention, but the guarantee length varies: Aspire and Bodyshape Gel 2000 show 5-year guarantees, while Bodyshape Boost 1000 Pocket Memory Mattress shows 1 year. That means a cheaper model can still be a smart buy, but only if the construction, firmness and guarantee terms suit the way you want to use a double bed. Recheck current price, stock and terms on the retailer page before you buy, because those details can change.

Buying questions
How do I know whether a double mattress will fit my bed frame and room?
A standard UK double mattress is usually 135cm x 190cm (4'6" x 6'3"). Check the frame label, measure the bedroom space around the bed, and make sure the mattress depth still suits your base, bedding and headboard.
What is the practical difference between Pocket Sprung and Hybrid on this shortlist?
Pocket Sprung models in this set, such as Aspire Pocket+ 1000 Tufted Mattress and Bodyshape Boost 1000 Pocket Memory Mattress, focus on spring support with different comfort layers. Bodyshape Gel 2000 Pocket Hybrid Mattress adds a hybrid build that is better suited to shoppers comparing support with more airflow-led comfort positioning.
Does the 100-night comfort trial make these mattresses lower risk?
It helps, because Mattress Online shows a 100-night comfort trial on the listed products, but it is still worth checking the latest terms, collection conditions and any delivery or removal charges before you buy. Trial cover does not replace checking size, firmness and frame compatibility.
Should I compare firmness, construction or price first when buying a double mattress?
Start with size and frame fit, then compare construction and firmness together. On this shortlist, Pocket Sprung suits a spring-led feel, the Hybrid option adds a different comfort style, and price only becomes meaningful once you know which build and feel you want.
