★★★★★Good bye to backache… I have been using the Sunday Ortho Latex 4 Mattress (Queen size) for more than 55 days now. Touch wood, I have not felt backache ever since. … I am a natural side-sleeper whereas my wife is a back-sleeper; both of us are comfortable sharing the mattress. Verified buyer · 22 Feb 2026

Questions about the Ortho Latex 4 Mattress.

Who is the Ortho Latex 4 Mattress made for?

Most people, and the safest pick if you are not sure. At 7/10 it is medium-firm: right for back sleepers, and fine for side and front sleepers too.

Skip it if you want a very firm bed (Ortho Memory, 8/10) or a soft one (Latex Plus, 6/10). We would rather send you to the right one than take this one back.

Will it help my back pain?

Medium-firm is what research found best for lower back pain (Kovacs, The Lancet, 2003). But a mattress is not a treatment and we won't claim it cures anything: see a doctor for pain that lasts.

You have 100 nights to judge, and one free swap to another model.

How firm is 7/10?

It is medium-firm on purpose. 2 inches of natural latex on top gives under your shoulders and hips; the firm core underneath keeps your hips level. Latex Plus 4 Mattress (6/10) is softer; Ortho Memory 4 Mattress (8/10) is firmer.

If it feels a little firm, a topper adds some softness on top without changing the support.

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.

Is a sale coming?

No. No sales, no coupon codes. The price you see is the final price, all year.

How does it arrive?

Flat, at full height. Never compressed. Most orders ship in 24 hours.

How long is the warranty?

Ten years.

Why 8 inches? Is there a 6-inch one?

It is 8 inches in every size. That lets 2 inches of latex sit on a core thick enough to hold your hips level. If it looks tall on your cot, you stop noticing in a week or two. Our 6-inch mattress is the Ortho Memory.

Ortho Latex 4 Mattress or Latex Plus 4 Mattress?

Both are natural latex.

Latex is the costly part of a mattress. If you like it firm or aren’t sure, Ortho Latex 4 Mattress. If you want it soft, or sleep hot, Latex Plus 4 Mattress.

See the Latex Plus 4 Mattress ›

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.

Will it sleep cool?

The top 2 inches are natural latex with open pores all through, so air moves through it.

Can I get a GST invoice?

Yes.
