Prices vary by size, so check the live retailer page before deciding whether the headline price still works for your chosen size.

What the retailer evidence shows
The shortlist spans pocket sprung, memory foam and hybrid constructions, which is useful because those formats behave differently in everyday use. Pocket sprung models like the Aspire Pocket+ 1000 Tufted Mattress are the most spring-led of the group, while the Bodyshape Gel 2000 Pocket Hybrid Mattress combines pocket springs with gel foam and is the clearest option here for shoppers thinking about temperature comfort. The retailer pages also show a 100-night comfort trial and free delivery to most locations, but review averages should be treated cautiously because several pages show very high ratings with very low review counts.
Buyer trade-offs to weigh
The main trade-off is feel: pocket sprung usually gives a more traditional bounce, memory foam adds more contouring, and hybrid designs try to balance both. That matters at this budget because the Bodyshape Vitality Memory Foam Ortho Mattress is the firmest-looking option in the set at £158-£305, while the medium-rated Aspire Pocket+ 1000 Tufted Mattress and Bodyshape Boost 1000 Pocket Memory Mattress sit in the middle. The Gel 2000 hybrid is the clearest pick if you want a cooler-sleep positioning in the evidence, but you should still compare the exact size price because the range stretches from £158 to £284 in the benchmark view.
Why these five mattresses made the shortlist
This page compares five Mattress Online mattresses from two brands, Aspire and Bodyshape, so you can narrow the choice quickly without opening every product page first. The list includes pocket sprung, hybrid, memory foam and a general mattress listing, which makes it more useful than a simple brand page because the options differ in feel as well as price. It is a shortlist for comparison, not a final ranking, and you should still check current stock, available sizes and the exact from-price on the live page before buying.
Shortlist benchmark at a glance
The benchmark price band for this page runs from £158 to £284, which is tighter than the wider product maximums shown on the individual pages and more representative of the under-£300 angle. Aspire and Bodyshape make up the brand mix, while the construction mix covers pocket sprung, hybrid, memory foam and one broader mattress listing, so shoppers can compare spring-led, foam-led and mixed-feel options side by side. review details are limited and some average ratings are based on very small counts, so the safest reading is to use them as a cue to verify the live product page rather than as proof of performance.
How to choose the right one for your bedroom
If you want a more traditional spring feel for a guest room or everyday use, the Aspire Pocket+ 1000 Tufted Mattress is the most straightforward pocket sprung option in the group. If you prefer more body-contouring comfort, the Bodyshape Boost 1000 Pocket Memory Mattress and Bodyshape Vitality Memory Foam Ortho Mattress shift more toward foam-led feel, with the latter marked firm. Before choosing, check the mattress depth on the live page, make sure the size works with your bed frame or bedding, and confirm whether the 100-night trial and guarantee terms are the same for the size you want.
Value notes by product
The best value is not always the lowest from-price; it is the mattress whose size, firmness and policy details still fit your needs. The Bodyshape Vitality Memory Foam Ortho Mattress starts at £158 and is the cheapest route into the shortlist, but the Bodyshape Gel 2000 Pocket Hybrid Mattress at £284 may justify its higher starting price if you want pocket-spring support with a foam comfort layer and a 5-year guarantee. The Aspire Pocket+ 1000 Tufted Mattress also carries a 5-year guarantee, while the Bodyshape Boost 1000 Pocket Memory Mattress has a 1-year guarantee, so warranty length is a useful comparison point alongside price by size.

Buying questions
Is the cheapest mattress the best value under £300?
Not necessarily. The Bodyshape Vitality Memory Foam Ortho Mattress starts at £158, but value still depends on size, firmness, depth and whether the current delivery and guarantee terms suit you.
Which mattress type suits a spring-led feel versus more contouring comfort?
Pocket sprung models such as the Aspire Pocket+ 1000 Tufted Mattress lean more spring-led, while memory foam options like the Bodyshape Boost 1000 Pocket Memory Mattress add more contouring comfort.
How much should I trust a 5.0 rating with only a few reviews?
Treat it as a weak signal rather than proof. Several pages in this shortlist show very high ratings but only a small review count, so it is smarter to check the product details, size options and policy terms first.
