Frequently Asked Questions

Do I need to rotate my mattress?

Yes, you must rotate your mattress once a month for the first 12 months and then once every 3 months thereafter. See full termshere.

I have back / joint pain issues, which mattress would be best for me?

The OTTY Original and Pure models are our most accredited when it comes to back and joint support. We would recommend these to anyone struggling with sleep due to these issues.

I overheat often while sleeping, which mattress would be best for me?

Our hybrid mattresses have long encapsulated spring units inside them, which do not store heat in between them and provide improved airflow compared to memory foam mattresses.

Additionally, some of our mattresses have bamboo & charcoal infused memory foam which further improves temperature regulation by wicking away moisture and providing a cool, fresh sleeping surface.

Because of this, we would recommend the OTTY Pure if you like a medium firm mattress, or the OTTY Firm, if you prefer a firm mattress. 

How can I get rid of my old mattress?

We offer a service at checkout to have your old mattress collected and recycled, for a cost of £40. This will usually happen at the same time as your delivery.

You can also usually have it recycled by your local council. 

What base do I need for my mattress?

OTTY can be used with a variety of standard bed bases, such as divans, slatted frames, adjustable beds, or platform beds. We highly recommend slatted bases because they allow better airflow beneath the mattress.

However, we do not offer any guarantee using the mattress with steel bed frames and thin steel supports, as they may not offer the essential support needed for the mattress. This lack of support could potentially result in sagging over time.

See T&Cs for full terms.

How long will an OTTY mattress last?

With proper care, the OTTY mattress should last you more than 10 years.

We guarantee them for 10 years as we usually recommend changing mattresses around every 8-10 years due to hygiene reasons, and because of new improved technology in our mattresses being added.

Are OTTY mattresses suitable for children?

Yes. As we only make medium to firm mattresses, we normally recommend them for children over the age of 3, all the way through to adulthood! 

We also sell waterproof mattress protectors which can be useful for the younger users.

  • How much to pay for a king-size mattress?

    The cost of a king-size mattress can vary widely depending on the brand, materials, and features. In general, you can expect to pay between £400 and £1,500. Premium options, like those with advanced memory foam or hybrid designs, may cost more, but we find that unless they are made from natural materials, price is not always an indictor of quality.

  • How much is a king-size mattress size?

    A standard king-size mattress in the UK measures 150 cm by 200 cm (5 feet by 6 feet 6 inches). This size provides ample space for couples, offering extra room for comfortable sleep.

  • Which brand king size bed is best?

    The best king-size bed brand depends on your preferences for comfort, support, and budget. Some top-rated brands include EmmaSimba, and OTTY, known for their quality materials and innovative designs. We recommend reading online reviews, which can help determine the best choice for you.

  • Are there 2 sizes of king mattresses?

    Yes, there are typically two sizes of king mattresses: the standard king and the super king. The standard king size mattress measures 150 cm by 200 cm, while the super king size is larger at 180 cm by 200 cm (6 feet by 6 feet 6 inches), providing even more space for a luxurious sleep experience.
