A few years ago a friend insisted that I buy an IKEA foam mattress. They come rolled up so small you can easily fit it in a compact car. I was way hesitant (I had a W Hotel Mattress before that, which was $$$ and not so great). I wound up getting the 2d most expensive one along with the 2d most expensive mattress topper. It is far and away the best, most comfortable mattress I have ever had. I put them in my weekend house and my guests always ask what kind of mattress it is. They are actually not that cheap – it will run you maybe 900 bucks all in for a queen – but they are very durable and comfy. (It’s basically the same thing as the much pricier Sonno mattress sold at DWR. You can google that if you want to know more about foam).
