Foam actually lacks the support of a traditional mattress. If you do end up making a switch, take a look at your typical sleeping position. Medium firm is good for side sleepers and firmest you can find is better for your back but honestly inner spring is best for your back.

I've suffered with backpain for almost a decade, a new foam mattress (Ikea) replacing a spring mattress seems to have helped a lot. It's a supportive foam with a memory foam top; firmer than the sprung mattress.

The only downside is, err, it doesn't bounce when you want to bounce, if y' catch my drift.

It feels quite different, definitely warmer (not a problem in UK), took a few days to get used to.

That's not true. You can buy a firm foam mattress if you want it.

I lasted a month on $600 foam. I woke up several mornings with sore hips. Finally, I called the local rescue mission to donate it. When I explained that I felt bad passing it on to someone else, they said they are picking up a couple of these mattresses each week! It seems like it's a hard adjustment for many... zing.

What was your sleeping position and what firmness of the mattress?

I sleep on my side. There's no firmness option. The foam arrives in the typical "I'm a mattress box" and expands.

Worth noting that some claim it gets softer after a few weeks.

Ah. It’s quite possible it was too soft and yes foam does get softer over time. There are some firmness levels between some brands of foam mattresses where they use different combinations of different types of foams that give a firmer feel but most box foam junk comes in a medium-soft variety to appeal to the broad market.

Mind sharing what the company/bed was?

Mine was Tuft and Needle.

FWIW, I've been very satisfied with mine for three years now. It's a much firmer foam than memory foam, and gives me just the right amount of support for side sleeping.

I suspected so, I just got a queen mattress from them two days ago, I've really enjoyed it so far.

I'm not sure how I ever slept on a non-foam mattress before.

They're so quiet and way more comfortable (as long as you get the firmness right) that I'd never go back unless forced to.

This seems to be the norm for us; VRBO a very nice place with a lousy mattress.

We buy a $100 foam in the box mattress (at walmart.com), pick it up at nearest store and put it in top of existing one

Then we say to owner your mattress is awful.. We won't review it that way..(they are very appreciative)

Next time we rent there there is a new non-foam mattress
