Mattress Forum

As for Sleep Science and the requested spec sheets -they emailed the cut-a-way mattress images that accompany each mattress on Costco's website. Unfortunately, no additional questions are then answered. I know I am not the only person asking for specific densities/ILD's etc...so right now I am a little soured on Sleep Science.

Wish I had more info to offer the forum....

Very interesting. Says a lot about the kind of customer service you can expect if needed after purchase.

They were pretty good about delivery, etc.  I think there have been complaints about their foundation, so I would probably avoid that.

I had a few questions about your experience with Sleep Science hybrid if you have a moment.

LONG story short, we took a chance on the Sealy Embody Introspection a few months ago b/c my husband doesn't like the feel of traditional Tempurpedic memory foam. He likes it with a quicker recovery time- less deep slow sinking, slightly bouncier. Which the Introspection was. We LOVED it for about 8-10 weeks. But, now it's already softening and sinking a TON and the past several nights we're both having back pain again. We've tried 100% latex which I loved on paper, but in real life, just never worked out for us.

I was researching the Tempurpedic Bellafina when I realized it was memory foam over latex over core b/c that helps give you the cush of memory foam, but a little more bounce back that other Tempurpedic models. Of course, the king set is like $3,400. Not out of the question, but steep.

When we were looking a few months back, Sleep Science no longer had a memory foam / latex hybrid available, but I see it's back now on Costco!

I just wondered how the one you had felt. You mentioned it was pretty firm? I think that's good for us b/c I am a stomach sleeper. I need a little cush, but mostly firm. I wondered if this bed had a quicker recovery time than other memory foam since it was sitting on the latex? If it felt supportive?

Most importantly, I wondered how your Sleep Science 5lb memory foam beds or toppers have keep their support? Seems like this Introspection has just turned to mush in the last few months. It started out wonderful and now just doesnt have the same support at all, which is causing back pain. I'm hoping to find one that will keep it's support and firmness for a few years!!! No sinking and sagging!

I'm thinking this Sleep Science hybrid might be a nice combo of memory foam and latex for us, the price is good at $1,149 kind mattress (would get the foundation elsewhere), and it's returnable forever on Costco if it didn't hold up.

Would love any additional thoughts you might have on Sleep Science-- either the hybrid, their 5lb memory foam quality, or both!

MANY THANKS!

Just checking in to see if you'd made a decision or a purchase? Did you wind up going with the Sleep Science hybrid? If you did- I'd love to hear what you think!

The hybrid one I tried was the 14" Celeste.  I found some reviews for the queen and king.    Note that a couple also say it was pretty firm.  The Celeste had a 10" base, 2" of medium latex and 2" of 5lb. memory foam.  So, pretty similiar to the hybrid one they have now, but not sure if they have changed the firmness of any of the foams.  I think they latex layer was dunlop, and probably too firm for my taste.  If they would have had 3" of a bit softer talalay latex, it might of worked for me.   I also didn't like the fact that it was 14".   Having the 10" base seemed unecessary to me, and would have made it too tall if toppers were added.   Still, I did like the plush feel of the memory foam from what little I used it, but the layers below did not seem to give enough.  It probably would have softened over time, but maybe not enough.  It felt supportive, because once you sunk in a bit, you definitely had some pushback from the latex layer.  The one nice thing about having some latex is that it gives it a little more springiness, as opposed to a dead feel of pure PU foam.

I checked the cover again of the old memory foam topper I have, and it says Sleep Innovations, not Sleep Science.  So, probably not the same.  That seemed to hold up well for many years.   Note that you don't really get a lot of support from memory foam.  You sink in most of the way, and it molds to the body.   So, that is what makes it feel nice, but too much can cause back issues.   You don't sink in quite as much in the more dense ones, so that is why they provide a bit more support.   Over time the cells do break down, and you get less support.   So, I tend to stick with 1-2" of memory foam and latex or springs for the rest.

If you want a fairly firm mattress with some plushness on top, the hybrid might be a good solution.  You can't beat the Costco return policy.  They delivered and picked up on schedule, and it did not cost me a cent.

May I ask what your mattress of choice is now days? That'll help me judge the level of softness you prefer in comparison to the 'too hard for you' hybrid if that makes sense :)

I've become pretty familiar with latex, memory foam, etc... in the past few months, so I should be able to understand your soft/firm preference based on what you're sleeping on now- assuming you love what you have now! ;)

I have pretty firm Sealy springs + 2" 32 talalay + 1" 24 talalay + 1" 5.9lb memory foam + 1" 19 ILD talalay.   In winter, I add 1" of 4lb mem-cool memory foam on top (I am using that right now).   In summer, I tend to like it firmer and cooler, so I often take off the 1 extra inch of memory foam.   I also have 1" of 5lb Sensus memory foam.  I would probably prefer the 2" of 5+ lb memory foam on top, but that often gets too hot for me.
 

Do you know much about Berkeley Ergonomics mattresses? They have a model called the Willow or Alpine. It's honeycombed pocket coils- like 1,200+ and 2" of ~25ILD talalay latex on top of that. Seems to be very good quality and like it would last 10 years or so. 10 year full warranty.

Keeping in mind that need a relatively firm mattress with good support b/c I am a stomach sleeper, and that I do like a bit of cush at the top, any thoughts on this combination? Or the reputation / quality / durability of Berkeley Ergonomics?

Many thanks!

No, I don't know anything about them, but their product seems pretty good on the website.  Generally, coils laced together (Sealy for example) will be firmer than pocketed coils.  Of course, it will depend on number coils,  coil thickness, how the pockets are made, etc.   The pocketed coils might wear out a bit faster, because there can be more work done by the ones you lay on top of the most (interlacing spreads the load out a bit), but I am not certain of that.    For a side sleeper, I like the combination.  In fact, if I was starting over today I would want to explore pocketed coils.  For a stomach sleeper, it is less clear.   You will have to make sure it is firm enough for your needs.

p.s.  I found that adding my 1" of 4lb memory foam on top of my stack made it too soft (a bit of back and kneck soreness), so I am back to using 4" of latex and 1" of memory foam.  I may try putting 1" of my 5lb memory foam under some latex to make it slightly softer for winter.
