Size guide
Is your mattress enclosed?
If your mattress sits inside a frame or in-between walls, we recommend a width and length thats 2CM smaller than the space it fits in. This gives you a 1cm gap all the way round, perfect for tucking in sheets with ease!
Does your mattress sit freely on top of a base?
If your mattress isn’t enclosed (such as a divan beds), then there’s no need to make any reductions to your measurements and you will get the best finish by going with exact dimensions.

Ordered a cheap alternative off eBay, waited over 3 weeks with no contact only to discover they had not even sent it. Cancelled order and sent size to Custom Size Beds – 3 days later it was here! Amazing! The quality is awesome and the comfort? Even better than our house bed! Do not hesitate to order from here you won’t regret it

Dealt with Miles and he’s a credit to your sales team, no bullshit, just decent technical advice and the proof is in the product I’m well happy
Lucy francis –
We needed a mattress for our caravan as my bad back can’t cope with sleeping on the seat cushions. The mattress arrived in 2 days and fitted perfectly so it can also be used as a seat. It was the most comfortable sleep I’ve had in a long time. No more aching in the morning! I just need to convince my husband to let me buy one for our bed at home!! Thank you.
Dawn Felton –
I stumbled across Custom Size Beds about a year ago as we have a handmade narrow spare bed. We were very impressed with the handmade mattress we received and it has been used many times since then. About a month ago we started looking for a new mattress for our king size bed. There’s just too much choice and even going into a shop doesn’t really help. Then I had a brainwave and rang Custom Size Beds to see if I could order the same mattress as we had on our spare bed, but as a standard king size. Of course we could! Ordered it on the Thursday, made on Friday, arrived with us on Monday. Fantastic service and such a comfy mattress.
Mica Lewis –
Super comfy product, amazingly fast delivery with only very short notice. Friendly and competent advice on the phone and impressed with the accuracy of our made to measure mattresses (x3 for our caravan). I will certainly be placing another order for my continental king size bed at home which is not a standard UK King size. Thank you guys, highly recommended! 🙂

David –
excellent product and fast delivery!
Zoe –
Absolutely thrilled with this mattress. It arrived within a few days and was so easy to carry upstairs and unwrap. There was barely any smell at all and i love the corrugated top, which is like having a massage! Also wonderfully firm – i didn’t realise how bad my old one had become till i slept on this – it’s great and i wish i’d found it years ago. Thank you!!

Cara Nix –
Absolutely thrilled with our new Mattress, thank you Custom Size Beds.
We were struggling to find a mattress for our unusual sized bed. The service and communication from Myles was fantastic.
Great quality mattress at a brilliant price.
Janet Stansfield –
We purchased the mattress for our narrow boat, the company were helpful, polite and delivery was super quick. Mattress is very comfortable, fits the bed perfectly and we’re very pleased, than you custom size beds.
Mrs. Jaqueline Biggs –
I am an American ex-pat living on a narrow boat. This company made everything very easy for me, including returning the mattress, having it cut down and sent out again because I screwed up the cm measurement (we use Imperial measurements in the States). The new mattress fits perfectly and I have a better night’s sleep on it than I had on my $1800.00 Sealy Posturpedic back in the States. I no longer wake up with an aching back, neck, and joints feeling like I spent the night in a dungeon of the Spanish Inquisition. At every step the customer service and delivery was superb and this mattress is literally a dream come true. Thank you M2MM.
Jens Bollerod –
I live on a boat so I needed a difficult to find shape and depth of mattress. The company was helpful, efficient and informative. The mattress that was delivered was excellent and I can’t praise them highly enough.
Martin Farrar –
Never had a foam mattress before. This one is comfortable and supportive
Lindsey dodgson –
I bought this matress for my little girl as she had a custom made bed and I needed a smaller matress, after struggling to find somewhere to make it I came across custome size beds and I order my matress after reading such good reviews. They even inboxed me to double check my measurements as I had written them down wrong, I’m so grateful they double checked with me otherwise it would of been to big for my daughters bed.
My daughter loves her matress and it is extremely comfortable.
Thankyou for all your time and help in making sure I had the right measurements, I will definitely be ordering from you again.
Sarah Thompson –
Really delighted with our mattress which we had made to fit our narrowboat bed. It arrived in super quick time and is very comfortable – we like a firm mattress and this fits the bill. We had the flat top version. I would highly recommend this company for their customer service and responsiveness.
NIck –
This is the first time i have ever written a review and the reason i am doing it is because it has been a hard time finding the right mattress online. My Wife and I spent ages looking online and visiting shops to try and find the right mattress. We bought from another company and had to return it as it was horrible. Then after more research i decided to take the plunge and go for this one. We went with the Flat top version. I have to say after a long time looking and making mistakes buying a cheaper version we have finally had a good night sleep. This is by far the best mattress i have slept on in my life and anyone looking for a good firm but soft top mattress look no further this is the one for you.
I am only writing this review because it was so hard to decide which one to buy, if you are the same as me and have been looking for ages trust me this is the one for you, you will not regret it.
Also the company themselves are extremely helpful and the customer service is what you hope every online business can be like. They originally delivered the wrong type and sorted it within a few days.
Thanks Custom Beds i will be recommending you and this mattress to friends and family.
