Phoenix,
Do you think a typical wooden foundation made for latex/foam mattresses would offer significantly more stability than the Leggett & Platt “Semi-Flex” foundation? We’re currently on a new SleepEZ 13,000 Cal King on top of a 1-year-old Beautyrest Black “Triton” foundation - I’m pretty sure it’s the L&P “Semi-Flex” foundation - I’ve seen interior pictures of both, and they look identical. We have our foundation on top of a cheap (free with the last mattress), but seemingly sturdy metal bed frame. After reading some of the previous posts, and your replies, I think we could achieve better motion isolation if we were to switch to a wooden foundation. Do you think that is the case? If we did, I would also get a new “super heavy duty” wedge-lock metal bed frame, just to cover all my bases.
I’ve found quite a few decent-looking assemble-yourself foundations in the $200-300 range for a Cal King through links from your site, googling, and searching eBay . We can also order the much nicer OMI foundation through a local dealer, and they’re on sale for 3 more days for 20% off with free delivery AND (that corny) ‘white glove’ installation for like $640. I feel it’s worth it to me to spend more for a presumably higher-quality product, also considering they will get it installed under that monster of a mattress. I think it’s a few extra hundred bucks well spent, especially since I don’t really have anyone to help me change out the foundation & frame, and I will probably kill my back otherwise.
That being said, am I wasting my time and money trying to improve on the existing semi-flex foundation? Shawn said we should use it and it would be just fine, but I’m not very happy with the motion isolation we have so far. He said it would get better as the top of the mattress cover “stretches out”. I would agree that is the case, it HAS gotten better, but I don’t think there is much stretching left, and I still feel a great deal of movement in the mattress, i.e. I can feel the mattress shake when my wife rubs her nose…however, I have not been woken up in the middle of the night by my wife getting in and out of bed, which may be more of a testament to my ability to achieve a deep sleep, rather than any comment on the mattress.
Phoenix, I would certainly welcome your expert opinion, especially if you could find out how much these two types of foundations “flex”.
Any contributions from other members are more than welcome.
Thank you!
