Questions about the Ortho Memory 4 Mattress.
Who is the Ortho Memory 4 Mattress made for?
People who want a firm bed: at 8/10 it is our firmest. At 6 inches it also sits lower, which many older customers find easier to get in and out of.
Skip it if you want a soft, sink-in bed, or you sleep on your side: take the Ortho Latex (7/10) or the Latex Plus (6/10).
Is it 6 or 8 inches?
6 inches as standard. 8 inches in four sizes: Queen 60 × 78, Queen 60 × 84, King 72 × 78 and King 72 × 84. The price shown is for the height you pick.
Can I get it in my size?
Yes. Any size up to 84×72″, and the 100 nights still apply.
What if it isn’t right for you?
Tell us any time in the 100 nights. We collect it free and refund in full, with no restocking fee.
Will it sleep cool?
Of our three, this one is the warmest, and we would rather say so: the memory foam is right at the surface. If you sleep hot, look at the Latex Plus.
Is a sale coming?
No. No sales, no coupon codes. The price you see is the final price, all year.
What is inside?
1″ memory foam (55D), 5″ high-resilience foam (32D), under an organic cotton cover. No latex and no springs.
How does it arrive?
Flat, at full height. Never compressed. Most orders ship in 24 hours.
Ortho Memory 4 Mattress or Ortho Latex 4 Mattress?
For a guest room, a kids’ room, or if you like it firm, the Ortho Memory 4 Mattress. If you sleep on your side or want a softer top, the Ortho Latex 4 Mattress.
How long is the warranty?
Ten years.
Why not a cheaper rolled mattress?
Rolling puts about 20,000 kg on a mattress built for people of 50–150 kg. It breaks the inner strength, goes too soft, loses its orthopedic support and lasts 30–40% less. We deliver flat.
Can I get a GST invoice?
Yes.
