Super King
If you’ve got a bedroom with enough space, a ‘super king’ bed is a great choice. The ‘super king’ bed size is 1835mm x 2030mm, which provides plenty of space, so is perfect for those who appreciate extra room. The mattress conveniently sits on two separate bases, which means you can get in and out of bed with less partner disturbance, making it ideal for early risers and restless sleepers.
1685mm x 2030mm | 66.3″ x 80″
King
This is a popular choice for couples, providing plenty of room across the sleep surface. Our ‘king’ mattress dimensions are 1685mm x 2030mm, making it ideal for those who like a little more space. While it is the same length as a ‘queen’, the ‘king’ size delivers extra width, which gives you more room to move.
1525mm x 2030mm | 60″ x 80″
Queen
There’s a good reason why our ‘queen’ size mattresses are so popular, they offer a great size for couples at 1525mm x 2030mm and fit into most bedroom spaces. Cosy in winter, but with enough personal space in summer, ‘queen’ size mattresses are a great choice. Delivering both comfort and practicality.
915mm x 2030mm | 36″ x 80″
Single XL
Children grow fast and ‘single XL’ beds are a popular choice for parents who want to get the most out of our ten-year lifespan. The ‘single XL’ is the same width as a ‘single’ (915mm), but offer extra length at 2030mm (compared to 1900mm). This provides extra room to stretch out, without taking up too much precious bedroom space. ‘Single XL’ beds are great for holiday homes and guest rooms, as they can comfortably sleep both adults and children.

I purchased an Exquisite Balmoral Ultra Plush, the bed is fantastic. I have never slept so well.
We absolutely love our Sealy. It somehow feels firm yet soft, unlike any bed I've ever slept in. We're always recommending it to friends and family.
Excellent service, communication and follow up. An exceptional bed which lives up to our expectations.
Love love love this mattress, so comfortable, soft but supportive, a truely restful nights sleep, would highly recommend.
The mattresses are really comfy and high quality. We bought them for our children but they are also comfy for an adult to sleep on. Excellent customer service too.
We have just recently purchased several Sealy beds and we are very happy with them, very comfy and great service from the team at Sealy.
Fantastic improvement on my old bed , have had the best nights sleep since it arrived !
Extremely comfortable!
My Sealy Posturepedic Elevate Ultra bed has been a crucial investment to ensure I wake up ready to conquer the challenges of the next day. Ever since I’ve had this Sealy Posturepedic Elevate Ultra bed, I’ve been sleeping really well - like a baby every night! So grateful for the sweet dreams and ache-free mornings.
They say buy the best bed and shoes, because if you are not in one you’re in the other. So I purchased the best, sealy crown jewel. Ultra comfortable, supportive and luxurious. My sleep tracker confirms I’m getting double the amount of deep sleep. I wake up refreshed, no aches or pains. Totally the best investment ever. Five stars all the way.
Great looking bed, feels and looks well made and even better to sleep on. Four nights into it and we are both sleeping more comfortably but also not waking with an aching back! Highly recommended. Thank you Sealy!
I have had my mattress and base for 20 years and it is still very comfy
We love our new bed! The perfect combination of support and comfort. We have the best sleeps we have ever had. When we go away the thing we are most looking forward to when returning home is sleeping in our bed!
We have the extra firm Elevate Ultra bed, love my bed, my previous bed caused lower back problems for both me and my partner, to the point I found it hard to walk. Then purchased the extra firm Sealy from Harvey Norman and with in a week my back issues subsided. Thanks Sealy for my great bed and my new health.
We couldn't be happier with the Sealy Melrose bed we have recently purchased for our teenage son. It is luxurious & he loves it. So much so we fear it will make it even more difficult to get him out of bed in the mornings!! The service we received was top notch & they went out of their way to accomodate us in a timely fashion. Based on our experience I would highly recommend Sealy & the Melrose bed.
The Crown Jewel Super King was such a good buy, I am always comfy at night now. 10/10
Amazing comfort and back support - I look forward to my amazing night's sleep every day.
The best bed I have ever slept on, I slept at a friends beach house a couple of years ago and had the best nights sleep, consequently as soon as I could put my bed (fairly new) at the Bach I did and have never been more pleased. Service and delivery exceptional.
Very comfortable, best bed we have ever owned! Highly recommend!
Soft and luxurious yet firm enough to provide good support. Should have replaced the old mattress years ago
I love getting into my Sealy Advantage bed every night.
Love it!! So comfortable and still thrilled with our purchase at the end of 2019. Such a treat having a stunning bed and better yet being able to support BCNZ. You guys are awesome Sealy!!
Very nice comfortable bed
We have the inspire plush with drawers and the bed is fantastic! Super comfy and the extra drawer space is great. Purchasing and delivering was super easy!! Highly recommend!
We have purchased 5 Sealy beds. We received fantastic service and our beds are divine. We are all so happy with them. Highly recommend.
Loving my new bed.
A quality product that is soooo comfortable.
Usually when I set expectations high for a new product I am happy for the expectations to be met, but in the case our new Crown Jewel bed it is difficult to put in to words how great it truly is... and what an over achiever when it comes to exceeding expectations. We have never slept so good, in any position. The only downside is our kids want to upgrade their beds to Crown Jewel's now, but at least this will keep them out of ours!
We're really enjoying our King size Elevate Ultra mattress. It's medium firmness but has just the right amount of soft comfort that makes for an easy sleep.
I love my new Sealy bed. I used to wake up with and experience joint pain throughout the day but since getting our new bed I am finally pain free. It is so comfortable and supportive I highly recommend it.
This bed is the best we have ever had. From the very first night we had it both my wife & I had a great nights sleep. I also spend 160 nights a year in hotels, on a wide range bed product and our Crown Jewel bed is the best bed I have slept on.
We purchased 2 only Parkhurst firm queen beds for our daughters in December 2021. The girls love their new beds. This is a good quality product and the customer service was exceptional. Thank you Sealy.
Fantastic beds. Excellent king singles for kids.
More than happy with purchase. Finally getting a comfortable sound sleep.
Very comfortable and no back pain!
We purchased our first Sealy bed four years ago and wouldn't buy another brand. Everyone in the family now enjoys a restful and well supported sleep in our Sealy beds. Would highly recommend purchasing a Sealy bed and love that the factory is based in Auckland providing jobs to Kiwi families.
So comfortable, we purchased this bed for my teenage son, and he absolutely loves it.
Fantastic mattress, highly recommend.
Very happy with my purchase, feel completely different in the morning after a good night sleep. The products are well made to suit all age group including people with back pain issues as it is designed to suit that also.
We have purchased 2 of these beds as replacements for some very old ones. These beds are beautiful to sleep on and we both get a magnificent nights sleep.
Sleep has been a struggle in recent years so when we decided to get a new bed, we knew it had to be an 'investment' in our wellbeing more than a transaction. Since we have purchased the Crown Jewel we have not had a bad night.
