Quick verdict
This shortlist is for shoppers who need a mattress that fits a small room or spare room without overcomplicating the decision. Aspire Pocket+ 1000 Tufted Mattress starts at £205, while Bodyshape Gel 2000 Pocket Hybrid Mattress starts at £335, so the guide is useful for comparing budget-led pocket sprung options against a more comfort-led hybrid. The price spread from £205 to £335 in the shortlist summary shows that the main job is to balance room fit, feel and value rather than look for one universal winner.
Top picks 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 shows
The clearest starting point is size: Mattress Online says single and small double are the most practical choices for small rooms and spare rooms, and it defines a single mattress as 3' x 6'3" (90cm x 190cm). That matters because bed frames are usually larger than the mattress itself, so the real footprint can be more important than the mattress label alone. The shortlist also mixes Pocket Sprung and Hybrid constructions, which gives you a useful comparison between spring-led support and a hybrid build if you want to weigh feel as well as room fit.
Buyer trade-offs to compare
The biggest trade-off is price versus specification. Aspire Pocket+ 1000 Tufted Mattress is the lowest starting price in the shortlist at £205, but Bodyshape Gel 2000 Pocket Hybrid Mattress moves up to £335 and adds the clearest temperature-comfort cue in the shortlist, so the extra spend may be worth it if you want a more comfort-led build. Bodyshape Ultra Ortho 1500 Pocket Mattress is the firm option here, but firmness should be treated as a comfort preference, not a room-fit decision, and you should still check mattress depth and bed-frame compatibility before ordering.
Why these mattresses made the shortlist
This is a comparison starting point rather than a definitive ranking. The shortlist contains 5 mattresses from 3 brands — Aspire, Bodyshape and Horizon — and that mix is useful because it lets you compare different price points, product types and feel profiles without leaving the Mattress Online range. It is especially relevant for guest rooms and solo sleepers, where a single or small double can be more practical than trying to squeeze in a larger bed.
What the shortlist shows at a glance
Current shortlist prices run from £205 to £335 in the benchmark summary, with a wider product-page range visible across variants. The shortlist includes Pocket Sprung and Hybrid mattresses, and the clearest labelled firmness choice is Bodyshape Ultra Ortho 1500 Pocket Mattress, which is marked Firm. Public review evidence is thin across the shortlist, so it is better to compare price, construction, size coverage and the 100-night trial information than to expect a strong review-count gap to settle the choice for you.
How to choose between these mattresses
Start with the room, then narrow by comfort. For very tight spaces, Mattress Online’s size guidance makes single and small single the most sensible checks, while small double is the better option if you want a bit more sleeping space in a spare room. After that, compare Pocket Sprung against Hybrid, then use the 100-night trial and guarantee information as part of the decision: Bodyshape Gel 2000 Pocket Hybrid Mattress is the hybrid comfort-led pick, Aspire Pocket+ 1000 Tufted Mattress is the budget starting point, and you should still verify exact dimensions because sizes can vary slightly by manufacturer.
Value buying notes
Value here is not just the lowest ticket price; it is the best fit for room size, feel and confidence in the purchase. Aspire Pocket+ 1000 Tufted Mattress at £205 is the clearest budget starting point, while Bodyshape Gel 2000 Pocket Hybrid Mattress at £335 asks for more spend but gives you the most obvious comfort-led positioning in the shortlist. Because the shortlist is a comparison tool rather than a final verdict, check the latest price, stock, size availability and delivery terms on the retailer page before deciding.

Buying questions
Which mattress size is best for a small room or spare room?
Mattress Online points shoppers first toward single and small double for small rooms and spare rooms. A single is 3' x 6'3" (90cm x 190cm), while a small double gives more sleeping space if the room can handle the larger footprint.
Is a cheaper pocket sprung mattress better value than a more expensive hybrid?
Not always. Aspire Pocket+ 1000 Tufted Mattress starts at £205, so it is the budget-led entry point, but Bodyshape Gel 2000 Pocket Hybrid Mattress starts at £335 and may suit shoppers who want the hybrid construction and the clearer temperature-comfort cue shown on the product page.
What does a firm mattress mean in this shortlist?
Firm is a comfort choice, not a room-size decision. Bodyshape Ultra Ortho 1500 Pocket Mattress is the firm option in this shortlist, so it is the clearest pick if you already know you prefer a firmer feel, but you should still check the size, depth and frame fit before buying.
