Ok, my turn please.
Background
We are looking for a mattress for a 6-yr old child, weighs ~40 lb.
The existing mattress is a very basic version from …a chain store. It has plastic/vinyl on one side (for waterproofness) and quilting on the other. The current occupant (6-yr old) says it is comfortable. It is not very supportive to me if I lay on it for a long time (older, ~135 lb) - there is not a lot of give. But it has a nice feel on the surface.
That mattress will be passed down, and we need a new one for the 6-yr old.
The existing bed will stay. The mattress rests on a homemade solid plywood surface with a thin pad stretched over it. The cover on the plywood is very thin, and is there for appearances and cleanliness, not additional comfort. The maximum suitable mattress height is 10".
The Search
A number of the child’s classmates have IKEA beds, and the parents think they’re just fine. We don’t want to take that route just yet (as mentioned in other posts).
I also visited one of the small retailer/manufacturers on the list for the Toronto area, and now I have more questions.
This store suggests one of two mattresses - both twin size.
- “Low quality” - “very basic, not a lot of padding, no quilted cover” (Their words) $140
- “Better” - $199
Mattress #1 (ok, #2 from above, but #1 to consider)
The “Better” mattress is twin, 2-sided (symmetrical) and has, from inside out:
a) “regular” coils - Bonnell, 380 count, 13 1/2 gauge, 5" high, made by Legatt & Platt (possibly in China in a U.S. run plant(?))
b) a “baked cotton pad”, ~ 3/8" thk
c) Polyfoam, 1.3 lb/cu.ft, 1" thk
d) quilting, polyfoam, 1.3 lb/cu.ft, ~3/8" thk
Pad, foam and quilting are the same on either side of the spring, so that adds up as: 5" coils + 2 x (3/8" + 1" + 3/8") = 8.5"
Mattress is said to be 9" high - pretty close.
They use 4 bow-tie shaped steel pieces along each long side to provide flex and support. Presumably one or two on the ends as well.
The Bar
Sitting on the edge of the mattress (as for story-time), I really noticed the bar running around the top of the coils that holds the system together. That alone is enough to make me look elsewhere. I compared it to the existing mattress at home, and on that one, the bar is still there, but is covered just enough by the quilted cover and/or comfort layer that extends over top and wraps around slightly. I can feel the bar but I have to try.
I’m thinking of asking if this manufacturer can copy that feature. That would make a big difference in usability, and if they cut their own layers, an extra 1" all around, both faces, shouldn’t make that much difference to the cost, no?
When I brought up the feel of the bar, the solution suggested by the owner was to make a smaller coil base and surround it with dense foam sides as in larger mattresses. This would be custom and much more expensive. I hadn’t yet examined the one at home to see their simple solution.
The Foam
I’m also hesitant about the polyfoam layer. From reading this site, it seems that 1.3 lb/cu.ft is very low. But the owner (who “passed” a phone interview by Phoenix) says that 1.3 lb is acceptable, is what “everyone” does for a basic mattress, and the mattress should last at least 8 years (with flipping and rotating).
Could you comment on the construction of this mattress?
I realize there can be variations with circumstance (weight of sleeper, flip the mattress or not, etc), but is 1" of 1.3 lb foam any “good”?
Does the separate extra 3/8" in the quilting make a difference?
Aside from the bar around the coils, the foam density is holding me back from what could be a simple purchase.
Other Notes
From the rest of our conversation:
a) They’ve been in business for 28 years. Lots of referrals, word of mouth, repeat customers (let’s hope after a decent time interval…), etc.
b) Owner doesn’t like memory foam - it’s a “waste of money” and lasts only a couple of years before it doesn’t come back
c) Foam density determines quality / durability. Higher density = more oil = more durability. [ in general terms ]
d) They use “compressions” to distinguish between firmness levels. e.g 18/35 is 1.8 lb/cu.ft foam that has been compressed 35 times, and is on the soft side. 18/50 is 1.8 lb foam that has been compressed 50 times, and is therefore firmer. [ I don’t expect to derive meaning from the numbers, it’s just a way to tell the levels apart ]
e) “Regular” foams (polyfoam) “don’t have a lot of fire retardants”. This is Canada which doesn’t have the same laws as in the 'States.
f) They “haven’t heard of” (or don’t use) the term “offset coil”. I think we ended up describing the same thing, but they called it something else (“Plasti-coil” or similar?).
Thank you for any advice.
