Frequently Asked Questions about sizes mattress
What are the standard mattress sizes in the UK and how do I choose the right one?
In the UK, common sizes are Single (90x190 cm), Small Double (120x190 cm), Double (135x190 cm), King (150x200 cm), and Super King (180x200 cm). To choose, measure your bed frame or base, assess room space for movement, and consider who will sleep on it. If you share the bed, a larger size like king or super king can improve comfort. Check the listing for exact dimensions and confirm if the depth matches your mattress topper and foundation.
Also consider room layout, door widths, and possible need for bed linens, fitted sheets, or duvet sizes that suit the chosen mattress size. Look for bundled deals that pair mattress size with a compatible base or protector to maximize value.
How do I measure my bed to know which mattress size fits?
Measure the inside width and length of your bed frame or foundation: use a flexible tape, measure from inner edges for width and from the headboard to footboard for length. Add ample space for sheets and a protector if needed. Compare with standard sizes (e.g., 90x190 cm, 135x190 cm, 150x200 cm, 180x200 cm) and choose the closest match. If your base varies in height, verify the mattress depth to ensure it sits correctly on the frame without sticking out.
If you’re shopping online, check the product details for exact width, length, and depth, and read customer questions for real-world measurements. Some listings on Wowcher UK will list both metric and imperial dimensions to help you compare accurately.
Are UK mattress sizes the same as US sizes, and does that matter for my purchase?
UK sizes differ from US sizes. For example, a UK Double (135x190 cm) is not the same as a US Full or Queen. If you’re buying from a retailer that ships internationally, check the exact dimensions in centimeters and inches and compare with your bed frame. When in doubt, measure first and convert to your preferred unit to avoid a mismatch at checkout.
Always review the size chart on the Wowcher listing and, if possible, contact support to confirm compatibility with your bed base and linens. This helps you avoid returning items and ensures a comfortable fit from day one.
What is the difference between a double and a queen or king size in the UK context?
In the UK, “double” typically refers to 135x190 cm, while “king” is 150x200 cm and “super king” is 180x200 cm. “Queen” is primarily a US designation and is not a standard UK label, though some retailers use it loosely. Always rely on the explicit dimensions rather than the name, and choose a size that fits your room and sleeping needs.
If you are upgrading from a smaller size, expect a noticeable improvement in sleeping space and partner movement. Consider the thickness and firmness options as well so the new mattress aligns with your preferred sleep posture.
What should I check when buying a mattress size for a small bedroom or shared room?
For limited spaces, prioritize widths that fit through doorways and balance with wardrobe and nightstand space. A single or small double may free up room for seating or storage, while a king or super king offers comfort if you have room to spare. Look for space-saving bed frames or storage solutions that accommodate your chosen size. Always review the full listing for width, length, and depth to ensure a proper fit in your layout.
Budget-conscious shoppers can search for bundles that combine mattress size with protectors, toppers, and bases, helping you maximize value while meeting size requirements.
Can I find deals on multiple mattress sizes on Wowcher UK?
Yes. Wowcher UK often features discounts across a range of mattress sizes, from single and small double to king and super king. You can save on bundles that include a mattress, bed base, and accessories. Use size filters and read product pages to compare price per centimeter and total value, helping you pick the best deal for your room size and sleep needs.
What about mattress dimensions in centimeters and inches—how do I convert?
Most UK listings provide both metric (cm) and imperial (in) measurements. A quick rule of thumb: 1 inch ≈ 2.54 cm. For example, 90x190 cm is about 35x75 inches. If you’re unsure about a size, convert the dimensions and compare with your bed frame. Many customers appreciate the clarity of both units at checkout, reducing the risk of purchasing a mattress that doesn’t fit.
What should I do after choosing a mattress size—delivery, returns, and setup?
Once you’ve selected the right mattress size, review delivery options and any promotions like free delivery or discounted shipping for oversized items. Inspect the packaging on receipt, test the mattress for comfort in the first 30-60 days if the listing includes a trial period, and understand the return or exchange policy. If something isn’t right, contact the seller or Wowcher support promptly to arrange a replacement or return. With the right size, setup becomes straightforward and you can start enjoying better sleep sooner.
