Outwell Dreamboat Double SIM

What we thought

We’ve had the Outwell Dreamboat Double SIM for a few months now, and we wanted to spend a decent amount of time using it before we posted a review.

Despite camping since I was a child, I’ve never properly used a SIM before. Those that I have tried in camping shops provided a pitiful amount of support, far less than I felt would be necessary for a comfortable sleep, and with space never an issue, a space saving SIM was never a necessity. Back when I first started camping, I preferred a simple single air mattress, and more recently we always used to use a double air mattress, before finally moving to the double Outwell Centuple camp bed.

Comfort has become a big priority to us over the years, but as we have upped our camping game and amassed a more elaborate camping setup, so saving space has now become a consideration too. The Dreamboat SIM looked mighty appealing, meaning we could cut down on space during short camping trips by sleeping on the SIM, and for longer trips we could use the SIM on top of our Centuple camp bed for added comfort.

The first time I came across the Dreamboat SIM was last year, when inside a friends tent, I noticed the substantial looking SIM she had and enquired about it. Then, earlier this year at the NEC Caravan, Camping and Motorhome Show, I got to see it again and this time had the chance to lie down on it and try it for myself.

I was utterly amazed at how comfortable it was, and having previously been a bit dismissive (primarily because of the price tag) I was instantly converted. Fast forward a couple of months and we were the proud owners of our very own Dreamboat Double SIM and we couldn’t wait to spend our first night under canvas on it.

Using the Dreamboat SIM for the first time

The instructions state that due to being factory packed, during the first use it would take a few minutes for the SIM to inflate itself. We found it took a good 10-15 minutes before we noticed a difference, and then, as recommended in the instructions, we topped it up by mouth, though It did take quite a lot of puff to achieve on that first us!

Outwell Dreamboat Double SIM Review

Attention to detail and quality always sets Outwell products aside, and when we topped up the SIM manually we were entertained no-end by the little smiley face that greeted us hidden under the valve cap.

Once inflated, we didn’t get any deflation overnight, and we found it fast and easy to deflate and roll to put away after use too. Deflating it is a simple matter of opening both valves and the technique we use is to fold the it down the middle, then to gently press the air out of it before tightly rolling it and replacing it back inside the carry bag.

We’ve used the SIM several times over the past few months, both on top of our camp bed and placed straight onto the floor and it’s fabulous. It has rapidly become one of our camping essentials, and for the level of comfort it provides, I wouldn’t consider camping without it. It IS a pretty sizeable investment, there’s no denying but we expect it to provide many years of use.

What we liked most

  • We love the fabric feel of the SIM and it felt much nicer than lying on an air mattress
  • Comfort is absolutely superb (we use the 7.5cm version), even for me as a side sleeper, I can very comfortably sleep on the SIM
  • Comfort is elevated to out-of-this-world when you use this on top of a camp bed
  • It’s really warm and cosy, providing excellent levels of insulation when we camped back at Easter when it was still very cold
  • It’s relatively compact, despite providing such a lot of padding
