Frequently Asked Questions

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

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.

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. 

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. 

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.

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.

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.

    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.

  • Will a king size bed fit in my bedroom?

    A king size bed typically requires a bedroom that's at least 12 feet by 12 feet to allow for comfortable movement around the bed and space for additional furniture. Measure your room and consider layout, including doorways and windows, to ensure it fits well.

  • Is a King size mattress better than a Queen?

    A King size bed offers 16 more inches of width than a Queen, giving each person the equivalent space of a Twin bed. This extra room can reduce sleep disturbances from partner movement and is especially beneficial for couples who are light sleepers or have different sleeping positions.
