Hi, The 15-month old mattress in my caravan has deformed due to bad design and poor mattress support (flexi-slats, not a solid base) and is slowly destroying my wifes back. We live permanently in our van so I have to resolve the issue ASAP as every medical person my wife has seen believe the mattress is the cause of her problem. I have made the under mattress base a lot less flexible and now intend replacing the mattress. Our old mattress is a Bonnell spring / innerspring unit and all the caravan mattress makers bar one say to go to a pocket spring mattress system. A great idea for comfort and spinal support but with one major drawback and that is a lot of additional weight over and above our current mattress. We are already teetering on our weight limits so I have had a look at a type of foam mattress using a material called Hydro Flex 200 which weighs about the same as our current mattress. My question is does anyone out there have a mattress using this material and if so are they any good? Any suggestions to solve this problem of replacing my Bonnell spring with something more supportive while not increasing weight in the van would be appreciated. Cheers

Hello Donesailing, and welcome here. Thanks for your question. Whilst not being able to answer your direct question, I have some info for you. Although my new caravan mattress had not deformed, it was way too hard and was giving me a huge backache, making it unuseable. I purchased a memory foam Mattress Topper which somehow magically turned the mattress in to one that is very comfortable and gives me a great nights sleep.
Cheers, John.

Hello donesailing and a very warm welcome. Just wanted to say hello. Our mattress was uncomfortable so we got an egg shell topper from clark rubber. The one with the 5 or 10 year warranty. Cannot remember which But the most expensive they have. I looked at cheaper ones but did not think they were very good. Anyway, no more problems. Also, i found with our old caravan that was single beds, i sat on it during the day and that caused the mattress to dip where i sat. turned mattress over, stopped sitting on bed during the day n bought egg shell foam topper. All better. Also, the slats under the bed where my hips lay, they r adjustable. The boards can b made hard or flexible by moving the thick rubber band that surrounds them. Good luck finding your solution.

Thanks for the prompt replies.
I have been down the topper (cool gel memory foam in my case) routine and the hump in the middle of the bed still resembles a small hill. We went 8-9 months before I stiffened the base up but by that time the damage had been done so I am prepared to toss the not so old mattress out and start again, within weight limits of course. My question on the Hydro Flex mattress still stands.
Cheers

My wife and I both have bad backs so we got a mattress and topper from makin mattresses. Only used the topper once as the mattress was very supportive. They have a special mattress for caravans so you can still lift the bed up for storage.
If they are in your area go and have a talk and try their product. Cheers

We went egg shell memory foam . I found it only ok to start , then got the idea to put mem foam on bottom.
Herself found it still ok , then I did hers . She likes it even better now as well.
So , we use the memory foam as a base & the original van mattress on top of it.
I also have a Very crook back .

I'm not familiar with the type of mattress you are referring to, but sold furniture and 100s of matts
Be aware that ALL foam and latex matts do not dispel body heat, but absorb and then reflect them back into your bodies. If youre staying in cooler areas they are great, but wouldn't have one in the tropics or dry hot areas (about half of Australia)
Depending on how much money you want to spend, you can buy "medical" mattresses designed for people who are in bed 24/7 and are designed to avoid pressure points (bed sores) - they are essentially a rubber type blow up bed which has a small pump (which would run off your Anderson plug, in house batteries or solar panels no problem.
These beds are made to shape themselves into the contours of each persons body without causing sag at the hips, but feeling like youre floating on air (which you are).
You would need to google medical mattresses and see the wide range available and their prices.
And being deflated like a blow up bed, theyre very easy to get into the van and lay out before turning on the electric motor. Has very little current draw, does make a slight humming, but people adjust the background noise very quickly

I'll admit I lost the plot reading your post (not cos of you). I just need to tell you something (my story maybe...I try not to make s&$t about me though).
My mattress was acceptable when I first got it. I continued to ache as I went along.....Ross river etc etc....I ended up getting this $xxxxy topper thing that didn't overly help how much I was aching (and not sleeping).
Turned out im coeliac. I can't ingest wheat (and other grains). Eliminating them was amazing!!! Now my bed is AMAZING - but it was nothing to do with the bed before.
So look outside the square is probably what I'm saying.

We go overseas a lot. Hotels mainly. and speak to staff. Most beds are HARD (harder the better for me). Commercial style. long term hard.
No matter where we go, the general staff concensus has been. There are a lot who complain about too soft beds. Very few complain about the hard beds.
Hard or soft. Do NOT buy a cheap one. they'll ALL sag. Nothing much under a grand and you'll be fine.
We have two home size Orthopaedic 8in singles in this van. A Grand each. Perfect sleep every night. Caravan ones in bin. Never had a bad Roadstar mattress though.
Also.
we did try one of those super duper (try 3 grand a pop)
multi foams onea few yrs ago.
Comfort fine.
But as others we've tried.
ALL foam ones (no matter the density.)
feel HOT\warm. up here in tropics.

We have a new mattress it's a queen as we had the same problem as you are having, we got ours from here www.mister-mattress.com
the one we got is the Ruby Deluxe have a read of the description of it . 10 year warranty cost us a bit $1000 but boy oh boy what a difference. I used to get up after a nights sleep and my hips used to ache wife's back would ache and we both used to get pins and needles in arms and according to the doc this was the mattress not supporting our necks and upper back . So saying all that these problems have been totally eliminated since we had this new mattress took a couple of weeks to get used to it like any new bed but it has been worth every penny we are in our van 24/7 too a good nights sleep welll it's money well spent. Have a look at the web site it has quite a bit of info. Best of luck

I would suggest you go to your local mattress store,select an innerspring with a pillow top you like and have it made to the shape that suits your bed.Don't fiddle about with makeshift foam underlays,do the job properly. There are also a few companies that specialise in caravan mattresses to your specs.there is one in Newcastle if I recall. You can't beat proper support and comfort for a good night's sleep.

We went with a full memory foam mattress. Much lighter and very comforable. Don't go with cheaper versions as you will be disapointed in a year.

We have a fully sprung double mattress in our caravan but the 4'' thick double foam mattress in our off-road camper-trailer is way more comfortable.
An example of, expensive is not always the best option.

Keith.
You KNOW why it so comfortable???
Cause it's 4 inches thick. ON A SOLID BASE. No sag.
I can't handle those foam ones. I have very high body core heat.
They get like an oven under me. even at the 3 grand level, multi layers.
The Best bed We got is a inflatable bed in pool in back garden.
Lovely and cooling, "float like a feather."
Don't bother with the "dance like a bee" bit. Chuckle.

We went with a memory foam mattress, one of those mattress in a box jobs. Very comfortable, lightweight and a better nights sleep than our expensive KK mattress at home.
