Choosing an emperor size mattress is a big upgrade — both in comfort and in the amount of space you need. At 200cm x 200cm (6ft 6in) or 215cm x 215cm (7ft), the emperor size offers exceptional room for couples, families who co-sleep, or anyone who simply prefers a wide sleeping surface. But because it’s a specialist size, it’s not always easy to find showrooms that keep emperor mattresses on display.
If you’ve been wondering where to actually test an emperor size mattress in the UK, the good news is that there are retailers with large-bed showrooms. And even if you cannot visit one in person, several leading brands offer generous at-home trial periods, which can be even more accurate than lying on a mattress for a few minutes in-store.
Below, you’ll find a guide to real physical stores that allow emperor-size testing, followed by details on OTTY and Panda’s in-home trials, a practical solution for buyers who prefer to test from their bedroom.
Where You Can Physically Test Emperor Size Mattresses in the UK?
Although emperor mattresses are less common on shop floors, several retailers specialise in oversized and luxury beds. These stores are your best chance of viewing or trying out emperor or similar large formats.
- The Big Bed Company (London Area)
The Big Bed Company focuses exclusively on extra-large beds and mattresses, including Emperor (7ft) and even Caesar sizes (8ft). Their showroom allows customers to experience different firmness levels, natural fillings, and support systems. If you want to try a genuinely oversized mattress in person, this is one of the most reliable locations in the UK.
2. Darlings of Chelsea (Nationwide Showrooms + Online Range)
Darlings of Chelsea offers a selection of emperor size mattresses and bed frames measuring 200cmx200cm. Their products are made using natural fillings such as wool, cotton and silk. While not every showroom will have an emperor mattress on display, many locations allow you to test similar models for firmness and comfort before ordering in the larger size. Their focus on high-quality, customisable furniture makes them a useful option for shoppers looking for premium emperor-size beds.
3. And So To Bed (Nationwide Showrooms)
Known for luxury bed frames and handcrafted mattresses, And So To Bed stocks Emperor and other large-size mattresses across selected showrooms. Availability varies by store, so it’s worth checking ahead, but many branches do allow you to lie down and test high-end, spacious mattress options.
4. Naturalmat (Devon & London)
Naturalmat manufactures organic and natural-fibre mattresses, including larger custom sizes such as Emperor. Their showrooms in Devon and London often have oversized models available to view or test. If sustainability and natural materials appeal to you, Naturalmat is worth visiting.
5. Beds Are Uzzz (Multiple UK Showrooms)
Beds Are Uzzz is a long-established bed retailer with showrooms across the South of England. While emperor mattresses aren’t always on display, they stock premium brands — including Vispring and Harrison Spinks — that can be ordered in Emperor size. Many locations allow you to test similar models in-store to get a feel for firmness, support, and overall comfort before placing an order.
Does John Lewis Sell Emperor Mattresses?
John Lewis & Partners sells emperor size mattresses from both Vispring and their own John Lewis brand. Vispring emperor models start from around £2,600, while John Lewis’s own emperor mattresses begin at approximately £7,999. You can try mattresses in many of their stores, though emperor sizes may not always be displayed, so it’s worth calling ahead. A 60-night comfort trial is available on many models for added peace of mind.
Tips for Testing in Showrooms
Finding an emperor mattress on display is not always guaranteed, so it’s worth keeping these quick tips in mind:
- Call before visiting: Not every location will have an emperor model on the floor, even if they list it online.
- Spend time lying on the mattress: Aim for at least 10 minutes in several sleeping positions. Comfort takes time to judge.
- Ask about made-to-order options: Even if an emperor isn’t displayed, many retailers can create a customised mattress using the materials and firmness you test in-store.
Testing an Emperor Mattress at Home:
If visiting a showroom isn’t practical — or you simply prefer to try a mattress in your own sleeping environment — at-home trials are one of the most reliable ways to find the right fit. Several UK brands offer emperor sizes with generous trial periods, allowing you to test them properly.
Options like the OTTY Hybrid priced at £849 and Panda Hybrid Bamboo priced at £1300, are both available in 200cm x 200cm emperor size and supported by 100-night trials. This give you plenty of time to decide on your comfort without any pressure.
At EmperorMattresses.co.uk, we bring these at-home trial options together in one place, making it easy to compare and find the right emperor mattress for your needs. Whether you’re leaning towards a supportive hybrid or a breathable bamboo-infused design, you can test your mattress properly before committing — and enjoy the reassurance of choosing based on real sleep, not a few minutes in a showroom.
